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.

    1) All LCDs these days use overdrive. Whether advertised or not. It's the only way that an LCD can get a response time better than roughly 15-20ms.

    2) This is an IPS panel. The Alienware is a TN. TN panels are able to do 120Hz better than IPS. That's one reason why this isn't 120Hz.

    3) 120Hz 2560x1600 is not doable with any current display connector other than possibly DisplayPort. Dual link DVI is only able to drive it at 60Hz, and HDMI can't even get up to native.

    Ordered an Asus 6870 DirectCU from Newegg, it has 2 DisplayPorts regular not mini. Will I have to use both to run 120Hz 2560x1600? On this or HPs 30inch?

    Neither is capable of 120Hz operation, so it doesn't matter how many connectors you hook up, it will never run faster than 60Hz. If someone were to release a 120Hz 2560x1600 panel, I believe that the newest DisplayPort standard could drive it with one connector. Other than that, no existing connector could pull it off.

    HDMI 1.3/1.4 have the same bandwidth as DVI, so they could drive a 2560x1600x60hz display.

    I gitcha ;) and agree, Dell should have put so much more into this panel, or should offer another 30inch with full RBG and a remote for switching inputs and volume tied to the Soundbar.

    What about the 10Bit color support? Where you able to test it during your review? I personally own a Dell 3011 but have never seen any option to enable it on my ATI/AMD GPUs (neither 5870 nor 6970) even through different connection options (DP, DVI, HDMI). It must be a professional-only feature, at least for the red GPU camp?! Maybe this is the way to gain access to a calibrated Delta-E below 1.0 ... ;)

    For those interested in this monitor for gaming, here's a comparison of Dell 3007WFP-HC and 3008WFP:

    http://www.digitalversus.com/duels.php?ty=6&ma...

    Unfortunately, none available anymore at dell.com :(

    I personally own the 3007WFP-HC basically for gaming and I can tell you lag is not noticeable at all (just as it was with the original 3007WFP).
    I'm not sure what method was used to measure lag in the U3011, but if it's similar to the older 3007WFP-HD I think we got a winner here.

    As somebody else said, we would like to see this monitor's specs compared to previous Dell models. The ones I've personally tried are:

    2408WFP (first revision) - Horrible Lag, no good for gaming at all. Average lag accordign to digitalversus: 69ms
    3007WFP - Unnoticeable lag, good response for FPS gaming.
    3007WFP-HC - same as previous.
    3007WFP - I haven't tried this one but most reviews show terrible input lag.

    What you'll find as common ground is that lag-free monitors don't have DSP (thus no OSD) and only DVI inputs, while the ones with more inputs and features (HDMI, OSD, monitor scaling) have noticeable lag. If Dell managed to cut lag while giving good features we surely have a good alternative in the U3011.

    Should have been RGBLED

    Should have been 120Hz which is totally supported by the current generation of graphics cards through displayport 1.2 or HDMI 1.4
  • Ryan Smith - Friday, January 14, 2011 - link

    HDMI: No. I'll go light on the technical details, but it doesn't have enough bandwidth to drive 2560 at 120Hz (it has about half as much as necessary). Frame packing actually makes this really ugly - for 3D as defined by HDMI it only has enough bandwidth for 1080P 24Hz.

    DP1.2: Yes. However this monitor has been out for a few months, which is to say that it came out before anyone had a DP1.2 display controller ready. DP1.2 displays won't be out until later this year.

    HDMI: yes
    DP: yes
    DVI: yes
    VGA: yes

    No one said it has to be at 2560. In an FPS, 1680x1050@120Hz is better than 2560x1600@60Hz.
