Input Lag

The HP 25" & 27" CW/er/es/XW monitors can all be considered delay free, but this is not surprising since most 1080p monitors are. Usually only multi-input 1440p-4k monitors have a around a frame (16.7ms) or two (33.33ms) of input lag. The Leo Bodnar device measures 9.7ms in the middle of the screen, but the Bodnar device has a built in delay and partially includes the monitors black-to-white pixel response times. Top screen Bodnar results are in the 3ms range, and both monitors tie with my CRT when using the SMT Tool. 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.
