With Dell having announced its upcoming 5120 x 2880 "5K" display that would be the equivalent of a Retina 27-inch iMac or Apple Thunderbolt Display and Apple rumored to be launching its own such display later this year, connectivity options for such displays have now taken a significant step forward with today's official release of the DisplayPort 1.3 specification by the Video Electronics Standards Association (via 9to5Mac).
The new standard offers a 50 percent increase in bandwidth to 32.4 Gbps, or 25.92 Gbps of uncompressed video data once overhead is accounted for.
The increased bandwidth enables higher resolution monitors, including recently announced 5K monitors (with pixel resolutions of 5120 x 2880) using a single DisplayPort cable, without the use of compression. It will also enable higher resolutions when driving multiple monitors through a single connection using DisplayPort’s Multi-Stream feature, such as the use of two 4K UHD monitors, each with a pixel resolution of 3840 x 2160, when using VESA Coordinated Video Timing.
Apple has been rumored for some time to be working on Retina iMacs and displays, but connectivity bottlenecks have been one of the factors slowing progress in that area.
The previous DisplayPort 1.2a standard offered enough bandwidth to support 4K displays without compression, but pushing resolutions to 5K has presented difficulties for connectivity. With the new DisplayPort 1.3 standard, which will presumably be built into future Thunderbolt implementations, computer manufacturers such as Apple will be able to fully support the new high-resolution displays set to hit the market in the coming months.

Apple may launch a new ultra-high definition 27-inch monitor later this year, according to LCD market research firm WitsView (via Digitimes). The firm claims that the display will boast a 5120 x 2880 resolution, which would be significantly higher than the 2560 x 1440 resolution found on the current Apple Thunderbolt Display.
However, it is unknown as to how exactly Apple would power such a high resolution display with the current DisplayPort 1.2 standard used in Thunderbolt 2. A number of Apple's computers including the Mac Pro (late 2013), 27-inch iMac (late 2013), and Retina MacBook Pro (late 2013 and mid 2014) are able to power 4K displays with one Thunderbolt port, but can only do so at designated refresh rates.
It is more likely that Apple would release a new monitor with a "Cinema 4K" resolution of 4096 x 2160, which is the maximum supported resolution by the DisplayPort 1.2 standard. Such a monitor would also be able to take advantage of the 20 Gbps data transfer rate of Thunderbolt 2 to stabilize performance at a high resolution.
An 27-inch 5K ultra high-definition monitor from Apple would also come after Dell's 5K display, which was announced last month and boast a 5120 x 2880 resolution at 218 pixels per inch. It is also unknown as to what technology Dell with use to power the monitor, although AnandTech speculates that the company may use Multi-Stream Transport (MST) to stitch together two 2560 x 2880 panels in order to provide 5120 pixels horizontally.
Apple's Thunderbolt Display debuted nearly three years ago, although it is hard to predict when the company will unveil a new monitor based the erratic upgrade cycle of past displays. In addition to a higher-resolution screen, a new Apple display would also likely feature an iMac-like design and USB 3.0.

Dell yesterday unveiled its new $2500 27-inch 5K monitor (UP2715K) that boasts an impressive 5120 x 2880 resolution at 218 pixels per inch. This ultra-high resolution places the monitor on par with Apple's Retina MacBook Pro, which has a pixel density of 220 pixels per inch, and would be the equivalent of a Retina 27-inch iMac or Apple Thunderbolt Display.
Dell does not detail the technology powering the monitor, but AnandTechbelieves the company is using Multi-Stream Transport (MST) to stitch together two 2560 x 2880 panels in order to provide 5120 pixels horizontally. Dell demoed the monitor to Maximum PC using a 5K H.265 video streamed from a workstation-class NVIDIA Quadro K5000 video card.
As outlined in our display roundup, customers have been looking toward a higher-resolution large display from Apple for some time, whether it be a true Retina version of the existing display or a somewhat lower resolution 4K display, particularly since Apple has been touting the 4K capabilities of the new Mac Pro. Rumors of Retina iMacs date back to 2012, but the machines have yet to appear, likely due to both cost and technological constraints.
With Dell listing its display at $2500, it is clear pricing remains a challenge for Apple's ambitions to launch Retina iMacs and standalone displays. Standalone displays may stand a better chance, as Apple has historically been willing to develop expensive large-screen displays priced in the thousands of dollars for its pro-level customers. An iMac almost certainly priced well north of $3000 could be a difficult proposition, however, so Apple may yet need more time for prices to come down before such a machine becomes commercially feasible.
Besides its impressive resolution, Dell's monitor ships with Dell's PremierColor technology and an edge-to-edge glass that includes both anti-smudge and anti-reflective properties. Also included in the display is an integrated media reader, six USB ports and 16W Harmon Kardon speakers. Video out support includes dual DisplayPort 1.2 ports for 5K video and a miniDisplayPort for 4K operation.
Dell's UltraSharp 27 Ultra HD 5K monitor will be available in the fourth quarter of this year.

Following an earlier report on the launch of the iPhone 6 and iOS 8, 9to5Mac has released a second report with details on OS X Yosemite and Apple's fall Mac plans. As has been previously mentioned, OS X Yosemite will launch in October, following iOS 8's September release alongside the iPhone 6.
The final Yosemite Developer Preview is expected to be seeded to developers on September 29, with a final golden master build coming around October 10, which suggests a late-October public launch date for Yosemite.
October will also see the potential introduction of the iWatch, as has been widely rumored, and Apple may also be planning to unveil several new products designed to promote Yosemite, including a smaller 12-inch MacBook with a high-resolution display and a new desktop computer, which may be an iMac or a standalone monitor with a 4K resolution screen.
Along with providing a few details on the desktop Retina machine, 9to5Mac's report echoes several details on the 12-inch MacBook previously shared by rumor sites, suggesting it will have a Retina display and a "thinner and slightly lighter aluminum body."
Apple believes that this new Retina MacBook will be a significant step forward in the laptop industry, and it is currently unclear if Apple will label this machine as a smaller MacBook Pro, a new MacBook Air, or as an entirely new line.
While it is possible Apple will market the aforementioned 4K desktop as a "Retina" machine, the technology for true pixel-doubling of the current 27-inch iMac and Thunderbolt Display's 2560 x 1440 resolution is not ready for market.
9to5Mac's sources indicate the 12-inch Retina MacBook and the iMac are on pace to ship in late in the third quarter or in the fourth quarter, but could be pushed back to early 2015, which is in line with recent rumors about the 12-inch Retina MacBook. A report has suggested the notebook's launch will be pushed back due to continued Broadwell delays.
Rumors have also long focused on a possible Retina iMac and/or a 4K display, and back in June, hints of a Retina iMac were found in the OS X Yosemite beta. Less has been said about a potential 4K display in recent months, but an update to Apple's Thunderbolt Display is long overdue.
Along with new Macs, Yosemite's introduction may also include updates to both iMovie and Final Cut Pro to improve support for video captured with 4K cameras.

Just released earlier tonight, Apple's OS X Mavericks 10.9.3 beta appears to have built-in support that enables all compatible 4K displays to be set at a "Retina" resolution, with an option for 60Hz output. The compatibility was first discovered by Twitter user @KhaosT, and was tested with both the Late 2013 Retina MacBook Pro and redesigned Mac Pro in conjunction with Dell's UltraSharp 24 Ultra HD Monitor.
To this point, OS X compatibility with 4K displays has been known to be somewhat erratic, as AnandTech revealed in December that Sharp's 32'' 4K display supported only one scaled resolution at 2560 x 1440. Furthermore, it was discovered that Apple had chosen to render text, menu and UI elements in the same manner as the Retina MacBook Pro, resulting in small and difficult to read on-screen elements on a 4K display. Various other 4K monitors were also found to be not properly supported.
Native support for 4K displays could also indicate that Apple is gearing up to release a higher-resolution Thunderbolt Display, as Apple last refreshed the monitor over two years ago. A number of other companies also introduced more affordable 4K displays at CES 2014 in January, with options from the likes of Lenovo, Asus, Seiki, and LG expected to hit the market throughout this year.

Last month, Dell announced several new "4K" displays for its lineup, including a teaser for an upcoming 28-inch model to be priced at "under $1000". While the pricing range was considered a breakthrough at the time, several other display manufacturers announced their own offerings at CES this week with pricing in the $800 range.
But as highlighted by Forbes, Dell has now revealed that its display will be launching on January 23 with an even lower price of $699.
The P2815Q will have a full 3840 x 2160 4K resolution and launch globally on January 23. Dell hasn’t yet discussed things like refresh rate or range of inputs (I’m sure DisplayPort is a given), but they do promise the same “screen performance” as the new UltraSharp 32 and UltraSharp 24 Ultra HD monitors. That’s certainly encouraging since their UltraSharp line is normally a cut above when it comes to professional displays.
The monitor will even include the ability to pivot to portrait mode as well as a range of adjustable viewing heights and angles. They’ll be selling accessories too, like a stereo sound bar and monitor arm.
Plunging prices for 4K/Ultra HD displays come just as Apple has launched its new Mac Pro, with its dual graphics cards capable of supporting up to three such displays simultaneously. The latest version of Apple's Retina MacBook Pro is also capable of driving a 4K display, taking advantage of the new Thunderbolt 2 standard to handle the throughput.
Many had hoped that Apple would release its own 4K/Ultra HD display alongside the Mac Pro, but the company did not do so, instead offering Mac Pro and MacBook Pro customers the option of adding on a $3600 32-inch Sharp Ultra HD display.

A number of companies introduced new 4K display options at CES this week, and, though some 4K monitors have seen early teething pains with the new Mac Pro, the new displays are expected to be compatible with Apple's new pro machine.
4K displays saw significant price drops in 2013 with a number of models introduced in recent months but these new options are, for the most part, significantly cheaper than currently available 4K monitors.
Lenovo debuted its ThinkVision Pro2840m, a 28" 4K display aimed at professionals with a 3840x2160 resolution. The monitor should be available in April for $800.
Asus also has a 3840x2160 display available, a 28-inch panel called the PB287Q, priced at $800. It will be available in the second quarter of 2014.
Finally, Seiki confirmed to MacRumors that it will announce a new 28" 4K display tomorrow, likely a budget-option as the company currently has a 39-inch 4K television available for just $500, significantly cheaper than similar alternatives.
LG's new ultra-widescreen non-4K displays
LG previously announced a 4K display, the 31-inch 31MU95, that is wider than most other options using a 19:10 ratio widescreen panel at 4096x2160, whereas the most other 4K displays use a 16:9 ratio. LG will also offer 34-inch and 29-inch options with much wider 21:9 screens at lower, non-4K resolutions. Those panels should be announced later this week at CES.

In its European Apple Online Stores, Apple has begun offering a 32-inch Sharp "4K" Ultra HD LED monitor. Retailing for £3,499.00 or approximately $5,700, the monitor has been available in the U.K. and other European countries since on or before November 30.
The 32-inch IGZO display, which has a resolution of 3840 x 2160, is not available in the United States and it is not clear why Apple has decided to offer it solely in Europe for the time being.
With its 32-inch class (31.5-inch diagonal) screen size, 3840 x 2160 high definition resolution and energy efficient edge-lit LED backlight, the Sharp PN-K321 monitor is ideal for professional applications where it's essential to view detailed information displayed with precision. This super-high resolution display allows you to view the content of four full HD screens on a single seamless display. It also features IGZO* technology, which supports increased pixel transparency and reduced current leakage, thereby making the monitor more energy efficient.
Sharp's LED display offers a 1.07 billion color palette, an 800:1 contrast ratio, and 350cd/m2 brightness. While it does come with DisplayPort support, it does not come with a Mini DisplayPort to DisplayPort adapter and will require users to purchase a third party adapter.
The appearance of the Sharp display in Apple's Online Store comes amid rumors that Apple is preparing its own 4K displays. Earlier this month, new display panels with DisplayPort appeared from AUO, sparking speculation that they could be used by Apple for a future 4K Thunderbolt display.
Dell debuted its own 4K Ultra HD displays earlier this week, offering a 32-inch model for $3,499, and a 24-inch model for $1,399. Dell also has a sub-$1000 28-inch model in the works for 2014, and as Apple and Dell have historically used the same panel supplier, Dell's offerings may provide an early look at what to expect when Apple does release its 4K displays.
Apple's recently refreshed Retina MacBook Pros are able to support a single 4K monitor and the upcoming Mac Pro is able to support up to three 4K displays. The Mac Pro may be on or near December 16, according to a German retailer that began taking pre-orders ahead of the product's launch, but it remains unclear when Apple might debut an updated Thunderbolt Display.
Update: Apple has removed the Sharp display from its online stores.

Following the initial revelation of some details on a new 24-inch 3840 x 2160 "4K" Ultra HD display from Dell yesterday, the company has now officially announced that the display launches today in the Americas with a $1399 price tag. A 32-inch model at the same resolution is also available for $3499, while Dell will be introducing a 28-inch 4K display in early 2014 with breakthrough pricing of under $1000.
24-inch UP2414Q (left) and 32-inch UP3214Q (right)
All three displays carry the same 3840 x 2160 resolution, giving them varying pixel densities ranging from 140 pixels per inch (ppi) on the 32-inch model to 157 ppi on the upcoming 28-inch model and 185 ppi on the 24-inch model.
The flagship Dell UltraSharp 32 Ultra HD Monitor delivers stunning screen clarity and detail with Ultra HD 3840 x 2160 resolution and high pixel density on an expansive 31.5-inch screen. Dell’s largest monitor allows for easy multi-tasking and viewing multiple applications side by side, and its ultra-wide viewing angle ensures that images and colors remain consistent regardless of the perspective. Designed for graphic designers, video and game developers, CAD/CAM designers, engineers, photographers and other power users, the Dell UltraSharp 32 Ultra HD Monitor provides an exceptional, high performance viewing experience.
With the same remarkable, pin-point clarity, the Dell UltraSharp 24 Ultra HD Monitor, users can enjoy color consistency and precision from virtually any angle thanks to an ultra-wide viewing angle on a 28.3-inch screen. The UltraSharp 24 Ultra HD Monitor allows customers to see more and do more with uncompromising picture quality that facilitates multi-tasking on a screen that delivers four times more data than a Full HD monitor.
Both the 24-inch and 32-inch displays support refresh rates of 60 Hz over DisplayPort 1.2 and 30 Hz over HDMI, as well as a variety of ports including HDMI, DisplayPort, Mini DisplayPort, four USB 3.0 ports, and a media card reader. Both displays also offer height, tilt, and swivel adjustments.
Exact details on the upcoming 28-inch model have yet to be released, but Dell says that it will offer "the same incredible Ultra HD screen performance" as the other members of the 4K display family and will carry multiple input ports for flexible connectivity.
Dell's new 4K displays arrive just as speculation regarding a potential 4K display from Apple has escalated ahead of the launch of the new Mac Pro later this month. Apple touts the new Mac Pro as being able to drive up to three 4K displays, but the company has not made any announcements about its display plans. The recent introduction of new 4K display panels from AU Optronics fueled speculation that Apple could be nearing an introduction for new displays, but Dell's displays may be the strongest hint yet that Apple may have something in the works given the two companies have typically used the same panel suppliers for their displays.

Dell has posted details of a new 24-inch monitor sporting a 3840x2160 "4K" Ultra HD resolution at 185 pixels per inch on its website (via Anandtech), suggesting the company may soon be selling 4K monitors to its consumer and business customers. No pricing or release date information, however, was included in the listing.

It is unknown if Apple would use the same 16:9 3840 x 2160 panels for a 4K display, as some have suggested that the company may prefer to push Thunderbolt 2 to its limit and support the wider 4096 x 2160 "Cinema 4K" standard given that the display will undoubtedly be targeted at professionals, many of whom in the film industry will be working with content using that resolution standard adopted for film production.
With the new Mac Pro, expected sometime this month, supporting up to three 4K displays simultaneously, there had been hopes that Apple would release updated Thunderbolt displays with 4K displays in the near future. Though these new 4K display panels have been announced from a number of potential suppliers, we have heard no firm details about new Thunderbolt displays from Apple.
Update: Dell has now officially announced the UP2414Q display, which launches in the Americas today for $1399 and will be available worldwide on December 16. A 32-inch UP3214Q model is also available for $3499 and a 28-inch model priced at under $1000 will follow in early 2014.

When Apple gave its full unveiling of the new Mac Pro at last month's media event, many observers were disappointed that the company did not also announce new higher-resolution displays to complement the radically redesigned professional desktop, which Apple touts as being able to support up to three 4K displays simultaneously.
But the recent introduction of new 27-inch and 32-inch 4K display panels from AU Optronics (via Reddit and AmongTech) is sparking speculation that Apple could yet have a display announcement in the relatively near future. Both panel sizes offer 4K resolution of 3840 x 2160 pixels, which could use the new Thunderbolt 2 connectivity standard to support either much larger desktops than with the 2560 x 1440 resolution of the current Apple Thunderbolt Display or high-quality "Retina" sharpness at an equivalent of 1920 x 1080.
Apple currently uses well-regarded LG panels in its Apple Thunderbolt Display, and it is unclear if the new panels from AU Optronics will meet Apple's exacting quality standards. Still, many have been looking for technology that would even allow Apple to offer a 4K display alongside the Mac Pro, and the new AU Optronics panels using the embedded DisplayPort (eDP) signaling standard embraced by Apple appear to be a significant step in that direction.
Even if Apple were to launch 4K displays using these panels, timing remains unclear as Panelook listings for the new panels indicate that they are "in production" but with customer sampling and mass production not scheduled until the first quarter of next year.
Also in question is whether Apple would even use 16:9 3840 x 2160 panels for a 4K display, as some have suggested that the company may prefer to push Thunderbolt 2 to its limit and support the wider 4096 x 2160 "Cinema 4K" standard given that the display will undoubtedly be targeted at professionals, many of whom in the film industry will be working with content using that resolution standard adopted for film production.

With just four days to go until Apple's October 22 media event in San Francisco, expectations for what will be shown are in many cases continuing to firm up, while in other cases questions remain. Our regularly updated Roundups section continues to offer a good overview of what is expected for each product and highlights the significant number of Apple products due for updates. Among the expectations for next week:
- iPad: Expect a new iPad mini-inspired design that is thinner, narrower, and lighter. [Read More]
- iPad mini: Retina display expected, but there have been questions about production and whether Apple be able to ship the new device in significant quantities, if at all, before the holidays. [Read More]
- OS X Mavericks: Reportedly due for launch before the end of the month, we should see a final unveiling next week. Other software updates including new versions of Apple's iWork and iLife suites, including iWork for iCloud, are also expected. [Read More]
- Mac Pro: Announced by Apple as launching "this fall" following a sneak peek at WWDC in June, Apple's radically redesigned professional desktop should get a thorough introduction next Tuesday. Some have speculated that updated displays may arrive to complement the new Mac Pro, but there has been no specific evidence of a display refresh. [Read More]
- MacBook Pro: An update for Apple's Retina MacBook Pro line has been expected for several months, moving to Intel's new Haswell processors for improved battery life. While it seems that Apple would want to feature the MacBook Pro improvements at its event, the list of products to be covered is beginning to get rather long and so it is unclear if the updated notebooks will make an appearance at or alongside the event or at a separate time. [Read More]
- Mac mini: There have been no specific rumors about the Mac mini, but it too is due for an update to Haswell processors. [Read More]
- An Apple TV wildcard: There have been some rumblings over the past several months that Apple is planning some sort of TV-related announcement for late this year, but there has been no concrete evidence of any imminent introduction. While Apple has been said to be planning its own connected television set product, that product may not be ready and the effort could continue to progress incrementally with an updated set-top box.
The display, which is aimed at retail/commercial applications (PDF), sports a 3840x2160 IGZO LCD panel and includes a capacitative touch interface and pen support. Sharp demonstrated the display running off an Apple notebook at the CEATEC Japan trade show earlier this month.

AppleInsider notes that inventories of the Apple Thunderbolt Display have begun running short at third-party resellers such as Amazon and MacMall, perhaps providing the first hints of an upcoming redesign. The display remains in stock at the company's online stores, but shortages tend to show up at third-party retailers first as Apple prioritizes shrinking supplies for its own outlets.
One of the most significant changes likely to make an appearance in a redesigned Apple Thunderbolt Display is the adoption of the thinner profile and new display assembly process seen in the company's latest iMac. The current Apple Thunderbolt Display borrows heavily from the previous generations of the 27-inch iMac, and thus it seems reasonable to assume that some of the iMac design changes such as new lamination procedures to make the display thinner and more vibrant will make their way to the standalone display.
But with that lamination process leading to shortages of the 27-inch displays used in the iMacs, an issue expected to persist until next month, Apple may hold off on introducing a new standalone display for the time being in order to prioritize the iMac.
Other changes likely to appear in an updated display are a move to USB 3.0 ports, which have become standard on Mac products, and the inclusion of a MagSafe 2 port for charging Mac notebooks. The current Apple Thunderbolt Display still uses the original MagSafe design for power passthrough, with Apple bundling a MagSafe to MagSafe 2 Converter to provide compatibility for owners of newer Mac notebooks.
Wednesday June 13, 2012 10:15 am PDT by Eric Slivka
As we noted on Monday, Apple's new MacBook Air and Retina MacBook Pro use a new MagSafe 2 charging standard that is thinner and wider than the previous MagSafe. In order to assist people using the new machines with older equipment like chargers and displays, Apple released a small MagSafe to MagSafe 2 Converter for $9.99 to ensure continued compatibility.
Apple has not updated its Apple Thunderbolt Display with the new MagSafe 2 standard, but as mentioned on its online store page, the company is now including a free MagSafe to MagSafe 2 Converter with newly-purchased displays.
It certainly is not a tremendous cost for Apple to include a $9.99 adapter (which actually costs Apple significantly less) with a $999 purchase, but it is a convenient inclusion for new purchasers who otherwise might not realize that they need a converter. Those who are aware of the new MagSafe 2 standard should also be aware that they do not need to purchase a separate converter if they wish to purchase an Apple Thunderbolt Display.

Ever since Apple released its first Thunderbolt-equipped machines earlier this year, reports have been surfacing from a number of users complaining about flickering issues on company's 24-inch LED Apple Cinema Display when used with the new Thunderbolt-equipped machines.
Apple has apparently quietly released a firmware fix for the issue, although the update has not been publicly announced and its existence appears to have only been revealed to a small number of customers who have escalated their issues through Apple's support systems.
A link (.dmg download) to the firmware update was posted to Apple's discussion forums earlier today, and a number of users who have applied the update have reported at least initial success with addressing the flickering issues. Users report having to reboot their systems and power cycle their displays in order for the displays to function properly after applying the update.
From the description included in the download file:
The 24-inch LED Cinema Display Firmware Update addresses an issue that may cause intermittent display flickering. This firmware will only install on the Apple 24-inch LED Cinema Display when it is connected to a Thunderbolt-enabled Mac.
This firmware update may not resolve the flickering issue if a Mini DisplayPort extender cable is used.
Some USB and FireWire devices may prevent firmware updates from installing correctly; disconnect non-essential devices and use only an Apple keyboard and mouse to apply the update.
Full instructions for installing the firmware update are also included in the documentation.
It is unclear why Apple has yet to publicly issue the firmware update for all 24-inch Apple Cinema Display users, and thus users should exercise caution in deciding whether to apply the update and prefer to check with Apple support regarding their specific issues.
Apple introduced the 24-inch LED Cinema Display in October 2008 and officially discontinued the model in July 2010 when Apple consolidated its display offerings with the 27-inch LED Cinema Display as its sole offering. Apple did, however, continue to sell off its remaining stock of 24-inch displays for a number of weeks after the official discontinuation.
Update: Apple appears to have pulled the firmware update without explanation.

iFixit has managed to get its hands on one of Apple's new Thunderbolt displays, subjecting it to one of the firm's usual thorough teardowns. iFixit was pleasantly surprised at how easy it was to disassemble the new display, and upon opening found a considerable amount of hardware inside to support the display and the docking station functions included in the package.
Both sides of the logic board are packed with enough chips that it’s hard to believe there’s no computer inside this display. Standouts include:
- Pericom PI7C9X440SL PCIe-to-USB 2.0 host controller
- L129NB11 EFL, which looks to be the Thunderbolt port controller
- Analog Devices ADAV4601 audio processor
- NXP LPC2144 USB 2.0 microcontroller
- Delta LFE9249 10/100/1000 Base-T LAN filter
- SMSC USB2517-JZX USB 2.0 hub controller
- Maxim MAX9736B Mono/Stereo high-power Class D amplifier
- LSI L-FW643E-2 open host controller interface
- Broadcom BCM57761 Gigabit ethernet controller
- Supertex HV9982 3-channel switch-mode LED driver IC
The display also includes an integrated 49-watt, 2.1-speaker sound system with a small 1-inch subwoofer, as well as a 720p FaceTime camera and integrated microphone.
Thunderbolt port on logic board for accepting incoming connection
As for the display itself, iFixit discovered an LG LM270WQ1 panel inside, the same as that used in Apple's Late 2009 27-inch iMac. Interestingly, the Thunderbolt cable carrying signal to the display is connected to an actual Thunderbolt port mounted on the logic board rather than hardwiring the cable directly to the logic board. The Thunderbolt cable is secured to the logic board port with a cover screwed down on top of the connector.
We chatted with iFixit's Miro Djuric about the curious observation that Mini DisplayPort displays can not be daisy chained off of an Apple Thunderbolt Display unless another Thunderbolt device is placed between the two displays in the chain, but the teardown unfortunately does not reveal the source of this limitation.
Some speculation has centered around the possibility that a single Thunderbolt controller chip may not have the ability to output the display signal required for both the included display panel and a connected Mini DisplayPort display panel. A separate Thunderbolt chip, such as one found in an intermediary peripheral device, may be required to generate the signal for the Mini DisplayPort panel at the end of the chain.
If you connect a Mac to the Thunderbolt Display what is sent is a Thunderbolt signal. DisplayPort is broken off and sent to the display but there's no way to propagate an additional DisplayPort signal to any other non-TB displays in the chain. The output on the Thunderbolt Display is literally a Thunderbolt output, it can't double as DisplayPort.
However, if you connect another Thunderbolt device that uses Light Ridge you can split any additional DisplayPort signals out of the chain. In other words, if you connect the Thunderbolt Display to a Promise Pegasus you can then chain on another DP panel.

With the new 27" Apple Thunderbolt Display now shipping to customers, Apple has posted a new support document outlining what can and can not be accomplished with multiple monitors on Thunderbolt-enabled Mac systems.
As far as compatibility, Apple notes that all Thunderbolt-enabled systems with the exception of the MacBook Air can handle two Thunderbolt displays, with a caveat for the 13-inch MacBook Pro being that the computer's internal display will not function if two Thunderbolt displays are connected. The high-end $799 Mac mini with discrete AMD graphics is also capable of running a third display via HDMI.
- MacBook Air (Mid 2011): One Thunderbolt display.
- MacBook Pro (Early 2011): Two Thunderbolt displays. Connecting a second Apple Thunderbolt Display (27-inch) to a 13-inch MacBook Pro will make the screen on the MacBook Pro turn black. This is expected behavior.
- iMac (Mid 2011 and Late 2011): Two Thunderbolt displays. iMac (27-inch, Mid 2011) with two Thunderbolt ports supports a total of two Thunderbolt displays regardless of which Thunderbolt port each display is connected to.
- Mac mini (Mid 2011): Two Thunderbolt displays. Mac mini with AMD graphics can support a HDMI compatible device on its HDMI port when using two Thunderbolt displays.
One other note of interest that will be a disappointment for some users is the disclosure that users will not be able to daisy chain a Mini DisplayPort display off an Apple Thunderbolt Display.
Mini DisplayPort displays will not light up if connected to the Thunderbolt port on an Apple Thunderbolt Display (27-inch).
The revelation is a bit of a surprise, as Mini DisplayPort displays can currently be daisy chained off other Thunderbolt peripherals. Some users had been hoping to reuse their existing Mini DisplayPort displays as part of multiple-monitor setups using the new Thunderbolt display, but will apparently be unable to do so.
Finally, Apple recommends that users daisy chaining the Apple Thunderbolt Display with Thunderbolt storage devices connect the display directly to the computer's Thunderbolt port, with other peripherals daisy chaining off of the display.
Update: Macworldappears to have demonstrated that you can indeed daisy chain a Mini DisplayPort monitor as long as it is connected to some other device than the Thunderbolt display. In Macworld's apparent setup, a Pegasus RAID storage device is placed between the Thunderbolt display and an older Mini DisplayPort display from Apple and all displays work properly.
It is unclear why simply inserting another Thunderbolt device into the middle of the chain allows the Mini DisplayPort display to function, but at least one MacRumors forum member has confirmed that he is unable to daisy chain his Mini DisplayPort-enabled Apple Cinema Display directly off of the new Thunderbolt display.

We've received multiple contacts that individuals have started receiving ship notices for their Thunderbolt Displays this morning. Scott from New Zealand offers up the above ship notice and expects delivery by tomorrow morning.
Forum readers have been organizing in this forum thread while waiting for deliveries. We'd previously reported that Apple had begun shipping demo units to stores last week. Apple has also been releasing various software updates to prepare for the display.
This update provides support for the Apple Thunderbolt Display and bug fixes for Thunderbolt device compatibility.
This company this week has also been pushing out firmware updates for its latest Mac models, addressing compatibility with the new display as well as issues with Thunderbolt Target Disk Mode and Lion Recovery over the Internet.

Apple today released MacBook Air EFI Firmware Update 2.1, a 3.99 MB update addressing a pair of issues on the company's latest MacBook Air models. The fixes include enhanced stability for Lion Recovery over the Internet and improvements for Thunderbolt-related issues including compatibility with Apple's forthcoming Apple Thunderbolt Display.
This update includes fixes that enhance the stability of Lion Recovery from an Internet connection, and resolve issues with Apple Thunderbolt Display compatibility and Thunderbolt Target Disk Mode performance on MacBook Air (mid 2011) models.
The MacBook Air EFI Update will update the EFI firmware on your notebook computer. Your computer's power cord must be connected and plugged into a working power source. When your MacBookAir restarts, a gray screen will appear with a status bar to indicate the progress of the update. It will take several minutes for the update to complete. Do not disturb or shut off the power on your MacBookAir during this update.
We noted last week that the new Apple Thunderbolt Display was beginning to ship to stores in anticipation of a launch in the near future, and today's release to ensure compatibility with the new MacBook Air offers further evidence that a launch for the display is near.
Apple announced the display back in July with a shipping date of "within 60 days", a timeframe that is rapidly approaching. Apple's order page for the $999 display is showing a 2-3 week estimate for new orders, but earlier pre-orders will likely ship sooner than that. We have yet to hear, however, of any pre-orders being prepared for shipment.
