Take a look at the manual for the monitor.and see what it's optimal resolution is. LCD monitors work best if you set the resolution to match it. Most 19" LCDs should be 1440x900, and 22" should be 1680x1050. 1600x1200 is a 4:3 ratio and will not work well.
I believe Ubuntu will let you set the resolution correctly, I don't know about debian..

Subject: [Novalug] how to find and set monitor parameters
after lifting lots of heavy CRTs I finally decided to get myself
a light flat-screen monitor, for $ 200 at MicroCenter. It works,
but the image looks squashed: it's wider than it would be on the
I connected it to two computers, through a switch. When I switch
from one to the other, the monitor changes to match that particular
computer. My question is: where do you set the parameters for the
monitor so that the image is right?
I do xrandr, (version 1.1) and get:
SZ: Pixels Physical Refresh
*0 1280 x 960 ( 339mm x 254mm ) *60
1 1024 x 768 ( 339mm x 254mm ) 85 75 70 60 87
on one computer (under debian edgy). I don't like this image much.
On the other computer (ubuntu 8.04, xrandr, version 1.2) I get
Screen 0: minimum 320 x 175, current 1600 x 1200, maximum 1600 x 1200
default connected 1600x1200+0+0 0mm x 0mm
1600x1200 70.0* 65.0 60.0
1400x1050 85.0 75.0 70.0 60.0
I like this picture better, but it's still not the right height to
One change I tried on the Debian computer is
4 1280 x 800 ( 339mm x 254mm ) 60
but when I selected this [with xrandr -s 1280x800]
the monitor blinked and didn't come back up.
(I rebooted, did some more things, and now it works again.)
I noticed that xrandr version 1.2, under Ubuntu, has many more
choices than the xrandr version, 1.1, under Debian. I upgraded,
but no change to xrandr occurred.
Any suggestions? Should I simply go to Ubuntu? do I need another
video card? how do you set the height to width ratio?
