The resolution you want is not listed in ‘xrandr’ output.
You probably should try and figure out why. A good place to look for a ‘hint’ as to why is the log file /var/log/Xorg.0.log. Look at that file. Does it mention 1920x1200 ? Do NOT post the contents of that massive file here. If you want people to look at it, instead please copy and paste it to the openSUSE paste site: SUSE Paste and press ‘create’ on that site and post here the URL/address where it is located.
Reference adding modelines for new resolutions, I’m trying to learn this myself (so I can write a guide) but I don’t know how to do this. I started researching this, and documented some of my early research starting in post#49 on this thread: openSUSE Graphic Card Practical Theory Guide for Users

That tells me that X could not obtain information on your monitor. Hence one avenue for an approach would be to try and find an edid.bin file associated with your monitor, and pass that to X.
I am not knowledgeable in that. I think deano_ferrari is our resident user who tries to help people with that. You could do a search on our forum for “edid” under the username “deano_ferrari” and see what you come up with.
as an aside there are some other curious entries in the Xorg.0.log file, such as:
10.538] (--) Chipset Supported AMD Graphics Processor (0x9710) found
10.539] (WW) fglrx: No matching Device section for instance (BusID PCI:0@0:20:5) found
10.689] (==) fglrx(0): board vendor info: third party graphics adapter - NOT original ATI
Which in my mind raises question about your hardware … but I suspect that is not relevant.
Hi AimarPL. Your display issue reads the same as this thread.
I notice your /var/log/Xorg.0.log output shows that your connected via an analog connection (CRT1 reference). This might explain the EDID issues. Are you using a VGA (D-Sub 15) cable? Can you connect via a DVI or HDMI cable instead?
You might find this minimal config in /etc/X11/xorg.conf.d/50-monitor.conf will work for you:
Identifier "Default Monitor"
## If your monitor doesn't support DDC you may override the
## defaults here
## Add your mode lines here, use e.g the cvt tool
Modeline "1920x1080" 138.50 1920 1968 2000 2080 1080 1083 1088 1111
Notice how I uncommented the horizontal sync and vertical refresh timing (by removing the # character). If you want to try it, you’ll need to edit 50-monitor.conf with root privileges. If using KDE, then type
Further to what deano_ferrai suggested you test, I note that your /etc/X11/xorg.conf file will take precidence over anything in any conflicting configuration you apply to a /etc/X11/xorg.conf.d/50-monitor.conf file. Hence you may when doing this test, wish to rename /etc/X11/xorg.conf to /etc/X11/xorg.conf.backup so as to not prevent the /etc/X11/xorg.conf.d/50-monitor.conf file configuration from being applied.
Good point oldcpu. The OP may wish to make these adjustment to /etc/X11/xorg.conf instead (if they’re confident in doing so), or if not, rename it as you suggest, and make the edits to the newer system files.
