After my old 17" CRT finally gave up the ghost (brand new from Gateway, May
1997!) I picked up one of the 19" widescreen LCD's at Fred's today.
The specs on the Hann-G and CTL monitors looked identical, so I picked up the
CTL because the mount was lower.
Brought it home, plugged it in, and it picked up the 1024x768 my xorg.conf was
set at. So I edited xorg.conf and put in the monitor's native 1440x900
resolution and restarted X.
Terrible! The result was a virtual 1440x900 screen on a 1152x864 physical
screen. Needless to say, things were a bit fuzzy as the monitor tried to
stretch pixels into 1152x864, and the top quarter of the screen was not
visible.
Looking at /var/log/Xorg.0.log, I saw that apparently I didn't have a good
default modeline for 1440x900. X was unable to come up with something the
LCD liked, and was using the virtual screen as a workaround.
To resolve it, add a modeline to xorg.conf like this:
Section "Monitor"
Identifier "CTL 195UW"
Option "DPMS"
HorizSync 30-80
VertRefresh 56-75
modeline "1440x900" 108.000 1440 1520 1672 1904 900 903 909 934 +hsync
+vsync
EndSection
(Everything after modeline is ONE LINE. The next line is the EndSection.)
Now I have my crisp 1440x900 display, with a 61MHz refresh rate.
So if you pick up one of the LCD's and have the same display issue try the
modeline above. It might work for the Hanns-G model also. They look to me
like the same monitor, just different plastic parts on the outside.
ATI Radeon Xpress 200G (RS480), onboard video using free xorg ati and/or
radeon driver. I do not see any difference between the two, and the
Xorg.0.log looks the same too.
I guess if you used ATI's proprietary driver you might not have this issue. I
haven't tried that solution.
