Display lag is a
phenomenon associated with some types of
liquid crystal displays (LCDs), and nearly all types of
high-definition televisions (HDTVs). It refers to
latency, or
lag measured by the difference between the time there is a
signal input, and the time it takes the input to display on the screen. This lag time has been measured as high as or the equivalent of 3-4 frames on a 60
Hz display. Display lag is not to be confused with
pixel response time. Currently the majority of manufacturers do not include any specification or information about display latency on the screens they produce.
