Results: Pixel Response And Input Lag
To perform these tests, we use a high-speed camera that shoots at 1000 frames per second. Analyzing the video frame-by-frame allows us to observe the exact time it takes to go from a zero-percent signal to a 100% white field.
The pattern generator is placed at the base of the monitor so our camera can capture the precise moment its front-panel LED lights up, indicating that a video signal is being received by the monitor. With this camera placement, we can easily see how long it takes to fully display a pattern after pressing the button on the generator’s remote. This testing methodology allows for accurate and repeatable results when comparing panels. Here’s a shot of our test setup.
The brighter section of the camera’s screen is what actually appears in the video. You can see the lights of the pattern generator in the bottom of the viewfinder. We flash the pattern on and off five times and average the results.
Here’s the screen draw result.
The Asus VG248QE, which has a max refresh rate of 144 Hz, is the only TN-based monitor we’ve tested this year. All of the others are IPS 60 Hz screens. The draw times are within a hair of each other, but Planar is at the lower end of the range. You won’t see any motion blur at video frame rates, but you might see some in fast-paced games. It all depends on how quickly you move your mouse and how speedy your graphics card is.
Here are the lag results.
The overall result puts Planar's PXL2790MW in the middle of the pack. As with most 60 Hz screens, a majority of gamers won’t have a problem. But those with faster reflexes will experience some lag. In this case, you’ll be waiting 4.8 frames from button press to on-screen response.

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.
