Results: Color Gamut And Performance
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 than sampling only the 100 percent saturations. Since there are no color management controls on the PXL2790MW, we're only showing the post-calibration graphs (although we’re sure they'd look pretty much the same out-of-box).
The color that’s most off the mark is blue, with oversaturation that begins at the 60 percent level. Green, yellow, and cyan are pretty much spot-on perfect at all saturations. Red and magenta are fairly close to their targets. The small errors on the CIE chart are more than balanced out by the near-perfect luminance values. Only 80 and 100 percent blue are below the line. All other colors and levels are within three percent of perfect. This has a tremendously positive effect on the final Delta E values, which are well below the threshold of visibility.
Let’s see how the PXL2790MW stacks up for color accuracy.
This is the most color-accurate panel we’ve measured to date. Even the factory-calibrated Samsung and Asus screens posted slightly higher numbers. For a monitor marketed as business-class, again, the performance is exceptional. While it doesn’t have the wider Adobe RGB 1998 gamut most photo pros require, it would be perfect for video and presentation graphics work. It also makes the PXL2790MW ideal for gaming and movie-watching.
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 shows the percentage of both sRGB and Adobe RGB 1998 gamuts.
Planar exceeds the sRGB gamut volume by just over six percent here. This is mainly due to the over-saturation of blue, and to a lesser degree, red and magenta. Given the invisible Delta E errors and superb color luminance, we don’t consider that a problem, though. The overall color quality of Planar's display is pretty much unequalled in our experience.
With only 73.3 percent of the Adobe RGB 1998 gamut, this monitor comes up short as a photographer’s tool. But it does deliver a little more color than other sRGB screens we’ve tested. For gaming, video, and productivity, there is none better.

16.2ms SMTT reviewed catleap or crossovers from greensum/korea LG S-IPS have been out for well over 2 years now at a $300 or less starting price. Get with the times toms.Reply
I agree with stoogie - also Toms needs to get an Overlord tempest and take a look at a real gaming 1440 panel that can do up to 120hz refresh rates. This screen isn't that special and the housing has been around in other variants for a year now as well.Reply
445 cd/m2 of luminance as maximum and 174.7655 cd/m2 as minimum ? Why do monitor manufacturers insist on delivering brighter and brighter monitors ? People don't use them like they are on display in a very well lit showroom, if you want to use one of these at home with just an indirect light source on the wall for some gaming at night, you're out of luck, this doesn't even reach the industry standard of 120 cd/m2 as adequate regular brightness, let alone the 50 cd/m2 that Tom's and many others consider an acceptable minimum to have in a darker room.Reply

What do you seriously think that another 27" 2560x1440 60Hz monitor that is already in class with a dozen other models identical to it, deserves an award?
How about a "First in Class" Award? There should be something... ;)Reply
Looks exactly like the "new" QHD Iiyama. Doesn't perform well. Costs a lot. What's the advantage, again?Reply
As for those overlord monitors, I wasn't impressed by them, mostly because I had it sitting next to a lightboost 2 120hz TN panel. Yes, the overclocked IPS panel has better colour (though that's largely negated by using it on minimal brightness in a dark room, like we've already been talking about), and it's certainly pretty and gives a lot of screen real estate... but it can't compare to a real 120Hz monitor, especially not one with a strobing backlight.
"With the new PXL2790MW, we quickly discovered there was no need for scaling in any program. The image is so clear that even the smallest text is fully legible." Technically admirable, but not enough for people like me with middle-aged eyes. The more pixels per inch, the happier my eyes are, but they still want decent-sized fonts.Reply
Now this sort of monitor clarity plus an OS that supports decent enlarged fonts would be really nice. Apps that scale well over a range of sizes would be even nicer. A 1000 pixel wide frame may be good for some people no matter how small it is; others of us would like at least a certain number of inches. Support all of us.
(Yes, I know that this isn't the monitor's fault. It's a poor convention in many parts of the software industry.)
I have never had a major problem with text clarity with pretty much any LCD since the first thing I make sure to do is set the panel or monitor to native resolution hardware scaling and turn off all windows text or font smoothing and windows set to the same monitor native resolution. I haven't seen one of these 2560 screens in person but I have experienced the default font issue that happens when you try and let windows smooth or scale. I don't like monitors with radiused corners because that makes the bezels even thicker then they need to be. I also don't like the way most monitor manufacturer try to hide the input plugs by making them inset and pointing down. It is a pain to try to plug or unplug anything when you can't see the plug without laying the monitor on its side. Also it makes no use to label the inputs if they are inset dark on dark. Make the text white.Reply
This deserves a "meh" award at most.Reply
QHD is not ready for gaming prime time yet, sorry folks.
