The refresh rate doesn't matter that much. If something changed than it has to be changed, if nothing changed, than nothing happens. For a tube monitor the picture is turned off and on and off and on. A LCD display is always on. "just by looking at the background of an empty desktop. It seems that the light is too intense, too violent (even when I reduce the brightness) and that my eyes keep on adjusting the focus with no interruption in an almost imperceptible manner." I suspect a wrong sub-pixel order for the fonts. If you look long enough at the bad fonts, then perhaps even a blank background that is ok, seems to be bad.

Computers don't use fields, so there only would be an effect for interlaced videos, if no deinterlacing is done, but for the desktop there is no interlace. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
