i recently purchased a monitor and was looking for a way to figure out input lag without a camera setup. one recommendation was to test your reaction time [1] on a known low-latency display. mine old one was a 1080p 21.5" Dell IPS LCD. I was worried that a 2k or 4k display would introduce lag, though at 60hz anything within 16ms g2g will feel the same and the 1440p Viewsonic i got advertised 15ms. Best reaction time (~190ms) over multiple trials did not change after switching to new display. Not scientific, but certainly enough to catch something as large as 20ms+.

For semi-new monitors you can find super in depth reviews at http://www.tftcentral.co.uk http://www.tftcentral.co.uk. They often include input lag. I highly recommend that site to get the true input lag of your monitor (without having to resort to your own tests). g2g typically measures the response time of the monitor which is a different thing than input lag. Most manufacturers won't even list input lag on their specs even though it's one of the most important attributes of a monitor since it affects everything. I could see the reaction time being a fun way to get an average with enough samples. I did 3 sets of 5 and it was 201, 194 and 196 as the average. But I think reaction time and being able to perceive input delay are different skill sets. I'm almost 40 so my reaction time sucks, but I can still notice a delay difference in apps when pressing a key.
