Presumably pro esports teams are measuring latency of their rigs to get the fastest gear where ms count? If typical gamers reaction time is O(300ms) and a keyboard, change can save 40ms, or a screen can add 80ms (extreme cases) seems like they'd be wise to be testing and verifying things. Anyone links to details of how esports teams are doing things here? I'm curious about the light-detection - do screens have a very tight synchronisation between different colours. Could the sensor be matched in some way with the specifics of the screen?
