ASRock PG27FFX2A Review (1080p/520Hz IPS)

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

One other benefit to such a high refresh rate is that input lag is very low indeed at just 1.25ms, so that's just a little over half a frame at 520Hz – certainly not something I'd notice in practice!
