Color Tracking Uniformity

Building on the 5-point testing we did in the Dell U2711 review, we’ve added testing at 9 different points across the LCD. To test this, we take our best center calibration profile and then test Delta E performance at 9 different places on the display.


 

We're adding a 3D plot visualization of color uniformity. As you'd expect, the top corresponds to top, right to right, e.t.c. as you would view the monitor normally.

We can see pretty clearly that calibration profiles are pretty localized - there’s a fair amount of deviation just about everywhere else. This is expected, especially since the display luminance isn’t the same everywhere, which we’ll illustrate later. We’ve shown in our previous Dell U2711 review that even the best monitors have this nonuniform color tracking; it isn’t to say that the display is worse at the edges, just different. Even at a Delta E of 3.17 at the most extreme, we’re still relatively in range, though much more would make a visual difference.

    With AMD video cards you can get rid of black borders all around as follows: bring up the latest CCC, go to Desktops & Displays, RIGHT-CLICK ON THE DISPLAY ICON AT THE BOTTOM under "Please select a display" and choose Configure, then select Scaling Options and set Underscan-Overscan to 0%.

    Thank you very much! That has been bothering me since I built my HTPC in January. Wonder why AMD set it that way by default.

    Bring back common sense. Glossy screens are asinine. GJ on that at least, Dell.

    Glossy screens are asinine on a laptop you take outdoors. Monitors are usually indoors and it makes sense for them to have some glatte or moss (half gloss, half matte, as seen on LCD TVs) to it. Full gloss really depends on the lighting of where it is.

    Time was a "green screen" meant just that - a text terminal with green phosphor on the front and nothing else. Nowadays you only see them attached to obsolete mainframes.

    I have two of the G2410's (non-H) version that I got with a discount code from dell.com for only $200 each, after shipping. I guess I got really lucky because I watched the price and discounts daily hoping to get more and it never got down that low again. A $140 price hike though for an adjustable stand just isn't worth it. Get these down below $250 and it would be worth it. The screen is really nice, though I wish they'd do a 27" led monitor and/or up the res to 1900x1200 or higher. I do miss that extra 180pixels in height on this screen

    I have two of the non-H as well. I missed the $200 sale, but got them for ~$250 last fall. Definately NOT the monitor you want for professional graphics design, but great for mixed use productivity, casual streaming/movies, and gaming (esp. at $250 or less). The auto mode was a little psychotic (brightness would vary in constant room lighting), so I moved to standard mode and manual settings. 15-17W consumption.

    Nvidia Geforce video drivers have the "Create Custom Resolution" and "Use NVidia Scaling" options that allow (with digital output) creating and scaling any custom or missing standard resolution at the correct aspect ratio. The trick is that scaling is done in the videocard, while a native-resolution signal is sent to the monitor. In essence, the monitor is displaying at its native resolution and doesn't "know" it is showing a lower custom resolution.

    For example, I find it more comfortable to use a custom 1536x960 custom resolution on a 24 inch (16:10) monitor

    For my parents' setup, I have created a custom 1080x864 resolution that is comfortably bigger for their old eyes while respecting the 5:4 ratio of their 19 inch LCD.

    It's too bad ATI is not offering these options.

    I did try that; I have a G2410 (hey, I bought it because it was on sale for dirt cheap at the time) and it's useless for 4:3 games.

    The G2410 has the annoying tendancy to stretch *ANY* 4:3 resolution that I've tried up to wide. WarCraft 3 doesn't look so hot.

    I did mess about with the nVidia drivers to try to create a custom resolution that would let me run 4:3 games at actual 4:3, but didn't get anywhere.

    I think it is unacceptable that a new monitor, even if it is just an update on an existing model, to not have HDMI.I use monitors now for my laptop at home and my laptop like many others does not have DVI out but rather VGA and HDMI. I can not use VGA if I am going to watch HDCP movies or use anything that requires HDCP. Sure I could purchase an HDMI-DVI converter but why not just add that extra HDMI spot to give everybody the chance to use their connections straight out of the box without having to purchase an adapter or look for a software solution.
