Brightness and Contrast
For brightness, black level, and contrast points, we use the same colorimeter setup described earlier. Specifically, we use an Xrite i1D2 with ColorEyes Display Pro, and take measurements at maximum and minimum brightness of white and black targets. Dynamic contrast is turned off. We also let the panels settle in for a half hour at the respective settings before taking any measurements.
If you were expecting an change in panel quality you won't find it here. The Thunderbolt Display is almost exactly the same as last year's panel but with a bunch of new features.
Brightness Uniformity
In addition to the performance at center, we’ve also added 9-point testing for brightness, both white and black. This is done the same way we measure color uniformity, except we only care about measured intensity. We set the monitor to near 200 nits, and then measure those 9 points.
The Thunderbolt Display performed very well in these tests. The display was very consistent everywhere. Although the center of the panel measured about 8% brighter than the surroundings, it wasn't noticeable in actual use. Brightness uniformity was remarkably consistent through the majority of our measurements, even better than the original 27 we reviewed last year.
White Level Uniformity
Black Level Uniformity
Viewing Angles
The Thunderbolt Display uses an IPS panel which guarantees good horizontal and vertical viewing angles. It doesn't matter how you tilt the display or from what angle you're looking at it (within reason), you'll get a fairly consistent image.

We replaced the video a couple of hours ago with one that has better audio. You shouldn't be seeing any links to the old one (and if you are, please say where).KPOM - Friday, September 23, 2011 - link
Are there any technical reasons for using Eagle Ridge in the Thunderbolt Display instead of Light Ridge, or is it just Apple being Apple? Had they used the latter, it would have been possible to daisy chain a Cinema Display directly to the Thunderbolt Display, right?Also, on page 8, there is a slight error. You say "The MacBook Air is a different story. Not only does it only support two displays, but the Light Ridge controller only has a single DisplayPort input so you're not driving more than one external display via a MBA no matter what you do."
I think you meant to say "Eagle Ridge" controller.

Why does Intel doesn't use the daisy chaining feature of DisplayPort 1.2 instead of encapsulating individual DP v1.1 streams???Ryan Smith - Friday, September 23, 2011 - link
If I had to go out on a limb, a single TB channel doesn't have enough bandwidth for DP 1.2.Trefugl - Friday, September 23, 2011 - link
I really really love the features that thunderbolt adds to the MBAs (e.g. FireWire and GigE), but I don't want to have to upgrade my entire monitor every time I want to upgrade to the next hub (for maybe USB3 support, or more ports, etc). This would only get worse if they started to put GPUs into the monitor, as GPU tech becomes significantly outdated every year or two, whereas a good monitor can last you 5+ years. Why can't they just release a sleek HUB that you can have sitting behind your monitor. Their approach just doesn't make sense if you already have a 27" or 30" monitor (nor for future upgrades).slashbinslashbash - Friday, September 23, 2011 - link
If you already have a 27" or 30" monitor, then yes, this doesn't make as much sense. If you are just now buying such a monitor, then the Thunderbolt Display makes perfect sense. There is nothing keeping you from buying a future box/hub that you describe, and using it between the MBA/MBP and the display (if the box/hub has a built-in GPU) or daisy-chaining it after the display (if you just want USB3 or other ports). That's the great thing about Thunderbolt, you can keep adding on to it. This display is not necessarily the final link in the chain, nor is it necessarily the first link in the chain. It provides useful functionality at a competitive price today, and the add-on capabilities of Thunderbolt will continue to be useful as new tech comes on line.Trefugl - Friday, September 23, 2011 - link
But what happens when the "next cool thing" comes out that we want in our monitors? Do you just replace a perfectly good monitor because you want to upgrade the addons? I suppose my feelings towards this stem more from the iMac, where you trash a good monitor every few years because you want a new all in one PC...slashbinslashbash - Friday, September 23, 2011 - link
Nobody trashes their old iMacs. The secondary market for Macs is huge. It's not like the PC world where your 3-year-old CPU and mobo would go for $100 so you just keep them as backup or put them into a machine for folding or something. With iMacs, if you upgrade at 3 years then you can probably still get around 40-50% of what you paid for it. 2008 iMacs are regularly going for $600+ on eBay. You buy a new one, transfer everything over, and sell the old one. It's almost like buying a car where you 'trade in' your old model.HMTK - Friday, September 23, 2011 - link
This must be a US phenomenon then.jecs - Friday, September 23, 2011 - link
Well, not a US exclusive or phenomenon.It happens worlwide because most Mac laptops or Pro Macs have been traditionally decent machines (not the best or the most specialized but sure not the cheapest). Some people like OSX but doesn't want to expend on new hardware.
And not a phenomenon because this is not exclusive to Macs but to many decent products that age well including speakers, cars, movies or albums and many more things.
