After tiring of my 19" LCD monitor, I recently treated myself to a Dell 3007WPF monitor -- that's 30" of LCD goodness! However, I had to resort to manual configuration to get the full 2560x1600 pixel resolution; the Suse configuration tool wouldn't let me get it into the full hi-rez mode, even with the Dell support disk with monitor profile. But, no worries, this is Linux and it is trivial to configure manually. Here's all it takes...
I simply edited the "Monitor" section of /etc/X11/xorg.conf as follows:
Section "Monitor" DisplaySize 646 404 HorizSync 30-100 Identifier "Monitor[0]" ModelName "DELL 3007WFP" Option "DPMS" VendorName "DELL" VertRefresh 56-76 Modeline "2560x1600" 268 2560 2608 2640 2720 1600 1603 1609 1646 EndSection
...then restarted X (log out and back in) and I was good to go.
FYI, my system configuration:
If you have the opportunity to step up to a 30" LCD I heartily recommend it -- it is wonderful to have so much information on screen at once.
