ASUS has packed an awful lot of features into the slim chassis of the ROG Swift PG32UQX, its 32-inch gaming monitor. Not only has ASUS included a 4K panel, but it also has equipped the PG32UQX with a 1,152 zone Mini-LED backlight and a 144 Hz refresh rate. The PG32UQX supports NVIDIA G-Sync Ultimate too, although there is no HDMI 2.1 on board.
