I’ve collected a group of 32-inch Ultra HD monitors for this comparison. Two of them, the XG321UG and the Asus PG32UQX, are Mini LED. The rest use edge array backlights – Philips’ 329M1RV, Asus PG32UQ and ViewSonic’s XG320U.
Pixel Response and Input Lag

The PG32UQ can overclock to 155 Hz, whereas the others max out at 144 Hz. However, that doesn’t provide an advantage. Response time is still 7 ms except for the MSI, which draws a full screen in 6ms. That gives it a slight edge in smoothness. Control response is in a small range between slowest and fastest; just 6 ms separates the group with the XG321UG in third place with 33 ms. That’s plenty quick enough for all but the most skilled players who will benefit from a lower-resolution 240 or 360 Hz display. If you want Ultra HD, though, it doesn’t get faster than these screens.
The XG321UG offers off-axis image quality typical of the latest IPS panels. There is very little light reduction at 45 degrees to the sides, just 10% or so with a red shift. The top view goes a bit blue with about 30% lower brightness. This is a shareable monitor by two users sitting around three feet away.

The XG321UG is one of the most uniform panels I’ve tested. It’s only eclipsed by the Alienware Quantum OLED AW3423DW and the Asus PA32UCG. With these numbers, you won’t see an issue with any of the monitors. Any result below 10% is visibly perfect. This is an impressive feat given the number of LEDs in use, though I’d expect nothing less from a $2,500 monitor.
