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 27 performed very well in these tests. The display was very consistent everywhere but the bottom of the display, even then it wasn't something noticeable in actual use.

    Also, the new Dell OSD controls are awesome. Proximity sensor with glowing controls? Bitching.

    Agree but it would have been nice to see the review compare the Dell and the Apple more especially since afaik there are no other displays like them.

    I for one am certainly loving my U2711. I would have liked split-picture function to be an adjustable Picture-in-picture function and the gaming mode is stupid but other than those small details I have no issues. It's hooked up to a PC, a Mac, a PS3 and a 360 all on the same time - great stuff.

    I dream of even more pixels per inch2, but for now the U2711 and the 27" Apple are the best choices bringing even more pixels per inch2 than a 30" panel. When someone makes a "retina" display in 27"+ size it will be a good day :-)

    he he, can you imagine the cost of a 27" retina display!!!!

    For sure it would cost an impossible amount at first but as with all tech the prices will come down. For example back some 2.5+ decades ago or so my dad paid something $8,000 for a phone the size of a small suitcase and now...

    Or to stay with computers. The first one I bought back when I was a kid cost $500, it had 1 KB memory total and for display I used an old TV and storage was a audio tapedeck. In other words some day... :-)

    yeah, one day!! And we'll be here reminiscing how a an base 8 core Mac Pro cost $3000 whilst talking about the new faster than light optical processors....

    Gotta love technology :-)

    Well that depends really on use. I would like a 27" screen with as few as cables as possible to use in a fairly limited space. So a monitor with built in speakers and a charger for my laptop seems like a reasonable choice.

    If ultimate colour quality etc is the goal though, surely you wouldn't even go for the 2711?

    I must admit to not knowing enough about colours to truly judge my U2711 but it is the first LCD that I have seen come close to my trusted old Sony GDM-F520 (a 21" CRT and perhaps the best CRT ever made).

    Most likely you can get better colour control with a high end EIZO or something like that but these new 27" panels offer finer pixels so it depends on what you're needs are.

    I really disslike 16:9, a 16:9 27" is just like a 24" 16:10. The loss of height in the 16:9 aspect is huge and very annoying.

    I also do not like the reflection that can occur to easily and distract me on the apple screens. It may look good at first but it's really annoying when using it.

    You forget that while the physical size is not as a 30" the 27" still offers a lot more pixels than a 24" 16:10 and the pixels are smaller as well.

    Check out the Dell U2711 to avoid the reflection hell (and gain a lot of nice features)

    "For some reason color tracking in the lower left of the screen was measurably worse than anywhere else."

    Guess what...
