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.

    The Dell has input lag and the HP doesn't have sRGB... :( LG please save us prosumer/gamer types!

    Any word on a refresh of the not-so-pretty LG W3000H?

    As the owner of a U3011, I have to say, the input lag isn't bad. Yes, it measures as worse than the HP, but 20ms is really not noticeable to the vast, vast majority of people. It's not like the old 2408 for example, which was ~60ms if I remember right. Reply

    I don't understand your problem with 1920x1080, it's slightly wider than 1920x1200 but that's it. There's no reason to be against it. Games on my Alienware OptX AW2310 look great. Reply

    Agreed. If you don't game frequently, then fine, higher pixel pitch is great (though text scaling can be a problem as other posters have mentioned). But, *BUT*, if you mostly game, then high res is, at best, counter-productive - it basically forces you to either 1) use a non-native resolution or 2) scale *way* back on the graphical "goodies" or 3) spend $600 a year on GPUs.

    I'd really like it if there was some focus on stuff that *matters* for gaming:

    - input lag
    - pixel response
    - refresh rate

    resolution, color pallet, viewing angle etc are great, and I'll take em', but not when it sacrifices the ability of the display to resolve moving images quickly.

    And, before you say it, I *would* just use a HDTV, except those are, on the whole, pretty junky, have terrible input lag, and are prone to "panel lottery" (where the manufacturer swaps out panels to save money but doesn't use a different model number. How is that even legal, btw?)

    They write the specs for it to have the lowest value for each panel of the right size; that way all of them meet the described specs on the product sheet and they can swap without worrying about false advertising claims. Reply

    You're right, it's clear that what they are doing is legal. But as long as they don't specify stuff like input lag *at all*, even if you wait for a review to tell you this value, the manufacturer can, and often does, swap out a new, lower-performing panel. Reply

    This is the 1st I've heard of input lag varying by panel make. I thought it was entirely due to the image processor used for overdrive/etc modes. Reply

    The lower vertical resolution sucks for trying to do any real work on it. Reply

    Slightly wider? It's shorter! Reply

    @DanNeely and TegiriNenashi,

    You are both right, I think the extra 120 pixels is both useful *and* not a huge burden on frame-rate. I was mostly thinking of the 2560x[whatever] resolutions that are real frame-rate killers.

    I guess I'm just willing to accept the loss since I really don't do a huge amount of work on this computer - mostly gaming as I said, so 1080p is an acceptible compramise.
