Input Lag

Both the Acer XF240H and Viewsonic XG2402 can be considered delay free (<3ms top screen Leo Bodnar measurement), but this is not surprising since most 1080p monitors are, especially gaming oriented TN panels. Usually only multi-input 1440p-4k monitors have around a frame (16.7ms) or two (33.33ms) of input lag.  The actual signal delay (input lag without including the pixel response times) is likely less than a millisecond, but an oscilloscope is required to obtain the "true" value.
