Color gamut is measured using a saturation sweep that samples the six main colors (red, green, blue, cyan, magenta, and yellow) at five saturation levels (20, 40, 60, 80, and 100%). This provides a more realistic view of color accuracy. Since there are no color management controls on the HP E271i, we're only showing the post-calibration graphs (although we’re sure they'd look pretty much the same out-of-box).

We’ve seen the oversaturation of blue on a few other screens, so this chart is not out of the ordinary. You can also see that green, yellow, and magenta are clocked slightly away from their targets. The errors are fairly small, as shown on the bottom Delta E chart. In fact, things look pretty good until you pass the 60 percent saturation level. Color luminance (middle chart) also dips for red, magenta, and blue as the saturation level rises.

Thanks to its excellent mid and low saturation color accuracy, the VG248QE’s color error average stays just below the visible level of three. HP's ZR30w is the only screen we’ve tested this year that finishes over three. This tells us that most monitors out there are pretty close to either the Adobe RGB 1998 or sRGB standard. It’s getting harder to buy a bad screen these days!
Gamut Volume: Adobe RGB 1998
There are basically two categories of displays in use today: those that conform to the sRGB/Rec 709 standard (like HDTVs) and wide-gamut panels that show as much as 100 percent of the Adobe RGB 1998 spec. We use Gamutvision to calculate the gamut volume, based on an ICC profile created from actual measurements. The chart is also expanded from previous reviews to include the sRGB gamut volume.

None of the sRGB-compliant screens we’ve tested reach the 100-percent mark. At 93.1 percent, the VG248QE does pretty well. This is more than adequate performance for any sort of entertainment use, from movies to games.

IPS is much better then TN
CaptainTom, 1ms makes a huge difference over 5ms. I didn't think it would at first until I bought one of these. Next to my old 24" HDTV that was my monitor for awhile, the difference is insane.

These high refresh rate monitors offer an incredible performance boost for first-person shooters if you have video cards that can produce frame rates close to the high refresh rates (or higher than 60Hz consistently). I've tried 1440p 60Hz monitors and can't stand the lower refresh. I've tried 60Hz surround setups and can't stand the low refresh. Once you go to these monitors, you develop a need for them. Nothing with lower refresh rates compares any longer. If you've never had it, you don't miss it and don't know what you're missing.
If you don't have the kind of GPU power to consistently get you beyond the 60fps mark at 1080p, 60Hz monitors are the way to go. I still wouldn't settle for cheap IPS monitors with crappy contrast ratios though. For shooters, the input lag is also a terrible characteristic of the cheap IPS monitor.
2 Titans for 1980x1080 resolution? That's a bit silly. You have spent $2000 for video cards and you are gaming on one 1980x1080 24 inch monitor!
You should have at least 3 of these monitors for a surround set-up.
Also - does anyone own one of these and notice that opening Pictures come up darker/dimmer than they look as thumbnails or in image preview??
ASUS... could you pretty please make us a 144 Hz 1440p IPS screen ??????

I second the 'pretty please'.
I would prefer the best of both worlds, but I don't think current graphics cards are quite up to the task. (At least not for less than a $2500 machine) Current IPS panels out there can pull the hz, but can't match the response times just yet.
Add in the fact that the industry will be pushing for 4k soon, and you can kiss 120hz goodbye for a while.
