Why you can trust Tom's Hardware
I have plenty of 4K 144 Hz screens to add to the mix with the 279M1RV. The Dough D03 Glossy is a reference-quality display and the Sony U27M90 isn’t far behind that description. At 32 inches are Dell’s G3223Q, BenQ’s EX3210U and Corsair’s 32UHD144.
Pixel Response and Input Lag

A 144 Hz monitor will almost universally score 7 ms in my full field white draw test. The resolution does not affect the result. The difference in motion quality comes down to the monitor’s overdrive. The 279M1RV is one of the best I’ve seen with fixed options. The Dough is the only monitor with a multi-step approach that lets you dial in the overdrive level very precisely. The Philips manages to hit the mark on its Faster setting. The other screens are close behind, but the Philips and Dough are standouts in the motion processing department.
The 279M1RV has lower input lag than any 4K monitor I’ve tested, except for the Acer XV282K. At 29 ms, it comes close to some of the 240 Hz screens I’ve reviewed. That translates to a super quick control response that is a real treat for a gamer of my average skills. Thanks to the Philips ' near-perfect motion processing, I ripped through intense battles with ease.
Viewing Angles
The 279M1RV has excellent off-axis image quality with a barely perceptible reduction in brightness and only the slightest color shift to red/green. Detail remains clear in highlight and shadow areas, more so than many IPS monitors I've photographed. It is one of the best I’ve seen in this test. The top view is typical of IPS panels with a blue tint and washed-out look. One could easily share this monitor with another player.
Screen Uniformity

Premium monitors like the 279M1RV rarely have visible uniformity issues and my sample was among the best in class. With just 8.1% average deviation from the center zone, I could not see any visible glow or bleed. Color and brightness were visually perfect in all patterns and at all brightness levels.
