Asus ProArt PQ279Q Monitor Review: 27-Inch, Wide-Gamut, QHD

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. Click on the photo to enlarge.

The brighter section of the camera’s screen is what will actually appear 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.

Twenty-three milliseconds is an average figure for an IPS screen in our experience. The PA279Q isn’t intended for hardcore gaming, but could serve well enough in a power user's multi-purpose (including gaming) setup if it needed to.

Here are the lag results.

Eighty-three milliseconds is a little slower than average in our round-up. For gamers desiring higher speeds, you really want to consider a screen capable of higher refresh rates, such as the unit we tested in Asus VG248QE: A 24-Inch, 144 Hz Gaming Monitor Under $300. That display imposes just under five frames of input lag.

    I think it's gonna be a hit with small studios and many freelance designers. I'd consider it when I upgrade my monitor in the future.

    People who cannot buy Eizo,Nec,Lacie...
    And are not happy with Dell and HP...

    It appears that my three Asus VS238H-P which cost me $360 total are going have a fairly long life span since 1440P still demands a hefty premium over quality 1080P displays. Hopefully we get some quality 4k displays for around 1k soon, the ASUS PQ321Q needs some competition :)

    What is the actual reason for calibrating at 200 cd/m2. The usual standard calibration is 120 cd/m2 at 6500K, see http://en.wikipedia.org/wiki/Color_calibration.

    The same panel can be found in Korean import models such as the Achieva Shimian QH2700-IPSMS which is roughly half the price. I would love to see Toms benchmark these premium panels against the cheap imports.

    Liking the new Eizo model w/ 240 Hz mode too.

    I want a QHD monitor, but I can't afford a gaming card that will work well with that resolution just yet. Maybe in a six months when Nvidia drops its Maxwell cards.

    Am I the only one that wants to know about upscaling quality? Last time I checked most monitors upscale pretty badly, and considering that this has an HDMI input I don't think it'd be unthinkable to have a 720p or a 1080p external video source.

    Why doesn't Tom's do the Overlord Tempest 2560x1440 IPS that will overclock refresh rates up to 120Hz? they are sellign for like $500 now and are killer!
