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.

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 do not accept payment for any review, this one included.

    Take care,

    I needed to start somewhere :) The next video review won't be an Apple product ;) And we do try to take great photos of everything we review when possible. I believe some of the best photos to-date have been of Android smartphones imho done by Brian Klug.

    Take care,

    It's a good review overall, but I do have a comment or two:

    - When switching to a completely different view, I would recommend using a quick transition such as a fade. It's rather jarring to just suddenly switch to a completely different picture like that.

    - If you'd like to make video reviews a bit more common, it might be worthwhile to consider a slight site change to make them a bit more accessible. Some sort of thing (tabs, buttons, etc.) near the top to switch between a text review and a video review.

    I'm trying to figure out though... did you build that entire stage area for the review, or is that a blue screen behind you? The shadows on the lettering made me wonder.

    I'm guessing they make the extra effort on Apple-products, simply because A LOT more people read those articles than the odd generic laptop review.

    If you've been following Anandtech for a while, you will see that they recap and explain (basic) technology and concepts in Apple review, because more people read them, and less tech savvy people read them.

    So it's only natural for them to put extra effort into Apple-reviews.

    PS: Anand, LOVE the video review. Please keep making them! :)

    Anandtech just loves Apple products, hence the special treatment. :)

    Maybe you're the fanboy. Its a good review just like any other, accept it.

    B3an is definitely the fanboy, there is massive bias when he posts in DT threads

    Part of it is that Apple products generally photograph better than others. It is hard to polish a turd, no matter how well you frame or light it. On the other hand, a beautiful object can photograph well under most circumstances.

    As for effort into reviewing Apple products, it is generally because they are on the leading edge of physical interfaces, form factors, and technologies. Three years after the debut of the Macbook Air and now there is a massive push from other companies to deliver comparable machines.

    The reasoning behind the Thunderbolt review is that it points to a very probable future for PCs, one in which your laptop is also your main computer. One option will be to have a laptop that plugs into a Thunderbolt hub (which may or may not be integrated into a display) which has all of your external devices and other things such as a dedicated desktop GPU, etc etc.

    It is interesting how much anti-Apple bias there is here. I'm typing this on my PC but I"m not blind to how vital Apple is to the industry.

    You're comparing the reviews Anand does himself to what some of the other editors do for cheaper/less advanced products. Look at Anand's SSD reviews (especially when its for a new/unique controller) and you'll see the same detail.
  • Kristian Vättö - Saturday, September 24, 2011 - link

    And at the same time, many SSD reviews consist of just benchmarks and a small introduction. Take for example the Samsung 830 SSD review, it's not that massive, mainly because Samsung isn't that big player.
