This ranking uses the maximum documented refresh rate at native 2560 × 1440. A faster mode at reduced resolution does not count. Only models with a current verified new offer appear, with price breaking ties in refresh rate.
Ranked by native 1440p refresh rate, then current new Amazon price for ties. Each offer shows when it was checked; shipping and checkout prices may differ.
Exact model: PG27AQWP-W
540Hz native, 720Hz at 720p
The ROG Swift PG27AQWP-W reaches 540Hz at native 2560 × 1440. Its separate 720Hz mode drops to 1280 × 720 and does not change this ranking. The glossy WOLED screen connects through HDMI or DisplayPort, with no USB-C video or KVM.
Exact model: PG27AQWP-G
Another 540Hz model with a separate 720p mode
The PG27AQWP-G Edition 20 is a distinct reference with the same documented 540Hz native 1440p ceiling and a 720Hz mode at 1280 × 720. It uses HDMI 2.1 and DisplayPort 2.1a. A laptop needs a video adapter or separate input arrangement because USB-C video is absent.
Exact model: UM.GXXAA.501
500Hz with KVM and speakers
The Predator X27U F5 reaches 500Hz at native 1440p. Unlike the two 540Hz ASUS screens above, it also has speakers, USB-C video at 65W and a KVM. The slower rank therefore brings more desk connections for a second computer.
Exact model: MAG 272QP QD-OLED X50
500Hz with a 15W laptop input
The MAG 272QP X50 matches the 500Hz native 1440p rate. Its USB-C port accepts video but supplies only 15W, and there is no KVM. It fits a gaming PC first, with an occasional laptop connection that keeps its own charger.
Exact model: MPG 271QR QD-OLED X50
500Hz and 98W for a second computer
The MPG 271QR X50 keeps the 500Hz native rate and adds 98W USB-C video plus KVM. DisplayPort 2.1 is available for the gaming PC. This combination matters if a laptop and desktop share the screen, keyboard and mouse.
