What determines the input lag for a monitor? What specs specifically?

[karmvir cheema]

Im looking at two monitors, one says "Take advantage of ultra low 0.001-frame input lag to enjoy the smoothest gaming experience! " this is the BenQ RL2460HT monitor

and the BenQ RL2455HM doesn't say anything about that, also which monitor would be better? gaming for ps3.

If it's for PS3 I highly doubt you'll notice any input lag between the monitors.

First off anything you are reading on a product page can not be relied upon. Testing at 3rd party sites shows that most manufacturer's lie .... er stretch the numbers a bit. Look for sites like TFTcentral for reviews. Scroll down near end for info on Input Lag
