Report: Input lag mystery unravelled (Part 3 of 3) Autor:
Siobhan Hayes 10/20/2009, 20:08 CET The suitability of an LCD
monitor for gaming depends not only on its response time and
streaking formation, but also, at least in the area of
programming, on the response time with which input from the user
such as mouse movement appears on the screen. A large number of
factors may play a role when it comes to lags, including the
monitor itself. The delay is also known as an input lag. Until
now, this delay was measured using stopwatch program which is
displayed in clone mode on a cathode ray tube monitor and an LCD
monitor. For measurement, the respective picture is photographed
and an average value is calculated from photo sequences of 50 to
100 images. However, are these values really meaningful? Is it
correct to assume that a CRT monitor itself has no input lag?
Does a significant lag arise when the analogue and digital
inputs are used – and what do the stopwatch programmes
themselves add? A Tektronix DSA71254 os
