I'm having a bear of a time configuring my new SyncMaster 240T. I am
running Debian woody with an Nvidia Quadro2 Pro graphics card. When I
run under Win XP, it works fine, so I know this isn't a hardware
incompatibility. The problem is that I have black bars on the left and
right of my screen. Even Xvidtune can't manage it. Nor could the
modeline calculator I found at
http://xtiming.sourceforge.net/cgi-bin/xtiming.pl.
The screen is 1920 by 1200 (i.e. whopping big) with a strange ratio of
16:10. It has a max pixel clock of 350 MHz.
Harry ten Berge, from the Netherlands was very kind in sending me his
Suse info. Here is what he sent:
Samsung:SYNCMASTER 240T {
DDC=SAM4254
Hsync=30-93
Vsync=56-85
}
Modeline "1920x1200" 254.59 1920 1956 2404 2740 1200 1308 1324 1373
That modeline didn't work for me. How do I use the DDC info in
XF86Config-4 ?
I tweaked the modeline as much as I could with xvidtune. Here is what I
have in my XF86Config-4 file:
Section "Monitor"
Identifier "Generic Monitor"
HorizSync 30-93
VertRefresh 56-85
Option "DPMS"
Modeline "1920x1200@60" 210.68 1920 2000 2752 2784 1200
