We again use the Open Source Response Time Tool (OSRTT), developed by TechTeamGB, to report monitor input latency.
Input latency is a new area of our testing, using the OSRTT Pro tool. Average On Display lag is reported at 1.96ms which is less than a half of a single frame at 240Hz (4.16ms), so nothing at all to worry about, and we'll build up a chart of comparisons as we test more screens.
