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.

    Not every product merits an in-depth review. 1 in-depth equals about 4 or 5 short reviews, and every site has to choose carefully how to spend its time.

    The first time we saw SF2000, there were *massive* reviews. If Samsung would suddenly put out an SSD that is a few dozen percent faster than the current fastest SSD, (and not cost the earth) it'll no doubt get an extensive review. When Apple puts out something very new that could well be the way of the future for the industry as a whole, they get a large review. Makese sense to me.

    And before you jump all over me on that score: Just look at the Sony implementation of Light Ridge on the current Vaio Z. That's a docking station that has everything this thing has (apart from the display) and some more.

    The market as a whole may well not go for integration into displays and integrated power supplies, but Thunderbolt/Thunderbolt-style docking stations seem likely to sweep the world.

    +1 top notch video review in every way

    Agree as well. While I definitely hope the text reviews will continue and receive the most resources, these video reviews are a great supplement, especially with less "numbers driven" products like displays and mobile devices.

    I wish all the CNET, television, etc. reviewers would take a look at this simple, engaging, intelligent review style and adopt it as well. Most reviewers spend way too much time trying to be entertaining and talking down to their audience.

    The text reviews will continue, this is simply something we're experimenting with to offer an augment :)

    It's always been my opinion that we should treat the readers as equals. It turns out that if you don't treat your readers like idiots then you'll find that you actually attract some really smart people :)

    Take care,
    Anand

    The video was quite good indeed.

    And I like the eye-level-approach. Especially since you had a pretty good balance between talking about the actually interesting bits and still keeping it easy to follow.

    Maybe in some places you might want to slow down just a tiny little bit. ;-)

    NOO!! If anything Anand, talk even faster! Throw it at me at full GigE! I'm a busy man!
  • Constructor - Friday, September 23, 2011 - link

    Just play the video in fast forward then. ;-))
  • pmcg - Friday, September 23, 2011 - link

    I agree too. What an impressive setup and continuous, cogent presentation. I have never seen a video of Anand but now that I have, I demand more! Should there be an anandtech.tv?
  • jleeworking - Saturday, September 24, 2011 - link

    Wow! nicely done, can we have more of those videos?
  • mymoon - Saturday, September 24, 2011 - link

    Also agreed! Well done Anand on the video review. Felt my time well spent.
