Color Uniformity

Now for color consistency, we take our best calibration profile from the very center at 200 nits and test color accuracy at 9 different places around the LCD display in an evenly distributed grid. We’ve shown before that calibration is actually very localized across the display, partly due to the brightness not being uniform, partly due to the discrete nature of the LCD panel itself.

LCD Color Uniformity

It's a bit surprising, but Delta-E actually creeps up somewhat high at the edges of the U3011. When you consider the sheer size of the display, it makes sense, but this is the highest I believe we've seen yet for change in Delta-E away from the center where we made our calibration profile.

    Good review!

    I read the ZR30w review earlier and that's the monitor I'd like to purchase when I upgrade from my 24" screen.

    Input lag matters as does colour.

    I have a hp 24" and tried a dell 24" which was 100$ more expensive and the hp had better colours and better (lower) input lag. It feels like Dell is falling behind HP.

    I agree, Dell is falling behind! I have owned three Dell Ultrasharp panels loved all of them, amazing color DisplayPort when no one else had it. I am looking for a 27" now and have no idea what to purchase. Anand says even the Apple displays are really not as amazing as their cost would dictate, and zero ports on those things. Does anyone make a glossy 27inch RBG LED with ports for $1200? Reply

    Made In china = GARBAGE, sure to fail quickly.

    Oh, and if you buy chinese junk, you are also supporting extreme human rights violations, slavery, forced child labor, fascism, evil, environmental raping, and the downfall of America.

    Is that a joke? I only ask because I doubt you don't own or haven't purchased anything that was made in china. Reply

    I have my Dell U2711, a pity it supports HDMI1.3 as 1.4 specification allows 4k resolutions.

    1.3a only supports 1920*1080, which means display port or DVI is still required for PC connections. Can't blame U2711 of not having it since 1.4 wasn't ready back then, but not having 1.4 support on product that's just came out is not forward thinking enough

    HDMI 1.4 only supports 4k at 24/30FPS. To do it at 60 FPS you need displayport 1.2. Reply

    Oh didn't know that. What a crappy interface :)
    I am not a big fan of HDMI to begin with, but all AV receivers nowadays uses HDMI.

    HDMI is designed by and for the TV industry, anything not needed for that is generally not included. 1.0 was a single link DVI interface. 1.1 and 1.2 just added additional audio formats. 1.3 doubled the bandwidth (to DVI levels) allowing higher resolutions (2560x1600), bit rates, more audio formats, and 100mbit ethernet over a sub channel. 1.4 added 3d and 4k support, but unless 2560 or 4k devices start moving towards high end consumer TV installations there really isn't any need for higher resolution support in the home theater market.

    DisplayPort is aimed at computer users and goes higher end. In the short term though it's double bandwidth will probably be used mostly to multiplex displays. AMD's 6xxx cards take advantage of this for eyefinity by allowing you to connect 3 displays to a single DP port using a breakout box. This will also simplify cabling for large video wall type installations.

    Everyone should have one of those Husky Torx drivers. They are extremely cheap, like $5-$6 and are super compact and easy to carry in any bag or toolkit. They come in handy all the time in the tech world, and no geek should be without one for the price. Reply

    Totally agreed, I've got that Husky Torx set and another with normal phillips/slot bits that have literally paid for themselves a thousand times over with how many things I've repaired using them. :)
