Viewing Angles

The XG279Q stands out among IPS monitors with excellent off-axis image quality, no visible color shift and no more than a 10% reduction in light output when viewed at 45° to the side. This is one of the best photo series we’ve seen to date. It makes this Asus very shareable even though it’s relatively small. From the top down, you can see a red shift and a 50% light reduction, typical of IPS screens. 

Screen Uniformity

Our light meter detected a slight center hotspot in our black field pattern test, but we couldn’t see it with the naked eye. Turning all the room lights off revealed a perfect black screen with no visible bleed or glow. Patterns at higher output levels showed no signs of color or luminance aberration.

Pixel Response and Input Lag 

Please click here to read up on our pixel response and input lag testing procedures. 

The XG279Q is one of the quickest and most responsive gaming monitors we’ve ever tested. Though you can buy monitors with higher refresh rates, Asus makes the most of 170Hz. 6ms is as fast as it gets for screen draw. Though you can eliminate motion blur with ELMB sync, there isn’t really much to speak of when frame rates top 100fps. Input lag is also lower than all the screens here and one of the lowest we’ve measured to date. At 21ms, you won’t have a problem one-upping your opponents. This is one fast and smooth display.

    Are there any tests of monitor speed using high speed cameras?
    1ms means black to white or gray to gray? Under what circumstances?

    I'd probably buy a monitor from another brand. I bought a VG279Q and a month out it would no longer run at 144hz without artifacting and blinking on/off. After a dozen ridiculous emails with suggestions like running the monitor at 60hz, finally sending the monitor in for an RMA to only have it come back two weeks later obviously not having been worked on as it had the same exact problem and me even sending a video of the issue which shows it happens instantly and is completely repeatable, I have given up and taken the monitor as a loss.

    Normally I like Asus, I've used ROG motherboards for my last few gaming systems, and like their WiFi routers. But after dealing with how completely incompetent their support is I won't buy from them again.

    Great review. I just purchased this and will be referencing the review for calibration when it arrives. I've been using the ASUS ROG PG27VQ for four years now and absolutely love it. I just started looking into purchasing a second for a dual setup. This seems to build upon that, so I'm excited to see how well it performs in what I'm going to throw at it. Gaming, Adobe's Creative Cloud suite, web/software dev and more. FTR this is will be my fourth ASUS monitor.

    Still waiting patiently for HDMI 2.1 monitors that can accompany a new 2.1 GPU and console.
