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.
