@MindControl,
Not sure why you are mentioning 44ms input lag and asking if people will feel a difference. I already said that it is when input lag gets over 30ms that you start to perceive issues. There are displays that aren't monitors that have input lag in the low 20's, though, so... yeah.
The best monitors have the lowest input lag available, but there are non monitor displays that have lag times in the low 20's. Some of them, like the Sony 40ES, don't even sacrifice PQ to get lag times that low. If you want to use a monitor to play with, then by all means do so. Just know, that there are other options, and again, the difference between 9ms and 20ms is negligible.
