ASRock PGO32UFS Review (4K Dual-Mode WOLED)

We again use the Open Source Response Time Tool (OSRTT), developed by TechTeamGB, to report monitor input latency.

One really fascinating area of testing has proved to be input lag, where we're focused on the ‘On Display Lag.' This is slightly high using the 4K/240Hz mode, averaging 6.32ms – so about a frame and a half at 240Hz, where each frame refreshes at 4.17ms. For context, other QD-OLED 240Hz monitors we've tested average more like 1.8-2ms, so this is definitely higher than expected.

It also carries over to the 480Hz mode, which averages 3.36ms – again, about a frame and a half of latency at that refresh rate. Definitely something for ASRock to look into with a future firmware update.
