How to solve the problem: Use a display with a low delay time (NOTE: This is
NOT the reaction time indicated by the manufacturer. This reaction time is only the
time the display needs, to switch a black pixel to get white or vice versa, but not
how long it takes from receiving the data on the connector until they are displayed
on the screen.) Please use a lower resolution or use a desktop background which is
better suitable for compression: Avoid photos for background or horizontally
graduated colors – better use monochrome backgrounds. They allow higher
compression -> higher frame rates. If – and only if the link has frame dropping, a
reduction from 30fps to 60fps saves 17msec and from 20fps to 60fps saves 34msec.
