Color Gamut And Performance
For details on our color gamut testing and volume calculations, please click here.
Whether you calibrate or not, the XL2420G’s color performance is exemplary. The CIE and luminance charts are about as close to perfect as you can get, and that’s reflected in a DeltaE result that's well below the threshold of visibility. The chart above represents the Standard picture preset in Classic mode.
Color takes a fairly wild ride in the FPS1 mode. Everything except for red shows under-saturation, and there are hue errors in magenta and cyan. Yellow saturation is the same at both 80 and 100 percent, which means the brightest hues are deficient in that color. We should be seeing higher luminance values to compensate, but they are off the mark as well. The resulting error averages 6.66 DeltaE, with some as high as 10dE.
While the color is OK in G-Sync mode, it isn’t quite as tight as Classic. The CIE chart looks good; all of the colors and saturations are on or near their targets. Luminance is the only flawed attribute, exhibiting generally low values throughout. In actual content, you’ll see a slightly less vivid picture than what you get from Classic mode. Fixing the gamma tracking in firmware would have a positive impact on the color results, we think.
Now we return to the comparison group:
The Classic mode measures well, with results rivaling the best professional displays. G-Sync mode is a little weaker compared to our other screens, but a 2.65dE average is still pretty low. Overall, we have no real issue with color accuracy in either mode.
Gamut Volume: Adobe RGB 1998 And sRGB
All of these gaming monitors come close to 100-percent sRGB volume, with Asus offering a four-percent bonus. In Classic mode, the XL2420G can easily be used for color-critical work given its excellent color and grayscale accuracy.
Otherwise, $500-$600 is Eyefinity/Surround, HD Projector, 60-inch Plasma TV territory. It's a tough sell for a display port-capable monitor these days in Adaptive/G -Sync, being that we are only moments before the flood.
And, the market is not in the high-end, at least, not for long. It's back where us poor slubs with 'pitiful' $200 gaming cards :lol: need the help.
From all the gripes about how the monitor gets so dim, that's actually a HUGE benefit for me - nobody every bothers to test what the minimum brightness a monitor can achieve, and many monitors, especially gaming monitors, fail miserably. I'd much rather have less eye strain than picture-perfect colors when I'm gaming at night.
However, for that price I'm disappointed it's only 1080P. I hope they come out with a free sync 1440P version that's cheaper than this monitor.
