Simple idea really - You click, numlock or capslock led lights up and with high speed smartphone, You can record frames of delay between numlock led and action on the screen.

Initial testing... On my 60hz hp ips, with 120fps recording, There are 12 full frames starting with numlock on to paint reacting. 1 frame on 120fps recording is 8.3ms... so total lag is 100ms... that can't be right. Seems like a lot even for 60hz monitor
