A question about X and monitors: need explanation, not help ;-)
by hazel from LinuxQuestions.org on (#5M276)
Having carted off my failing 19" monitor to the dump, I slotted in a 17" one as a temporary replacement. It made everything look much smaller (text characters expecially) and the colour rendering was unreliable, with the blue signal switching off after a while and everything coming up yellow. So I decided that the vga cable must be faulty and replaced it with the one from the 19" screen instead.
Now the colours are fine, but what surprises me more is that everything is back at normal size and has a nice crisp appearance. So I checked today's Xorg.log and compared it with yesterday's. I found this:
Code:
New
[ 61.358] (II) intel(0): switch to mode 1024x768@60.0 on VGA1 using pipe 0, position (0, 0), rotation normal, reflection none
[ 61.376] (II) intel(0): Setting screen physical size to 270 x 203
Old
54.508] (II) intel(0): switch to mode 1280x1024@60.0 on VGA1 using pipe 0, position (0, 0), rotation normal, reflection none
[ 54.510] (II) intel(0): Setting screen physical size to 338 x 270Why should changing the cable make such a difference to the way the computer sees the monitor?
