The best 1440p 144Hz monitor we've tested so far is the ASUS TUF VG27AQ. It's a versatile model with a stand that offers amazing ergonomics and it offers excellent gaming performance too. Its native 144Hz refresh rate can also be overclocked to 165Hz.

It has everything most serious gamers want in a monitor. It has native FreeSync support and it's certified by NVIDIA to be G-SYNC compatible. The input lag is extremely low and its response time at the max refresh rate of 165Hz is excellent, resulting in smooth motion. However, its response time at 60Hz is a bit slower, resulting in some motion blur, but luckily it has a black frame insertion feature to improve the appearance of motion. Picture quality is good as it has decent out-of-the-box color accuracy, it gets bright enough to combat glare, it has excellent gray uniformity, and with its IPS panel, it has wide viewing angles.

Sadly, it has a low contrast ratio, which is expected from an IPS panel, and even though it supports HDR10, it doesn't display a wide color gamut, so HDR content doesn't look all that different from SDR. On the upside, it has built-in speakers, so you don't have to buy an external setup if you don't want to. All in all, this is the best 1440p 144Hz monitor we've seen so far.
