I can only get 640x480 when using a BNC cable

amy

I have a Samsung SyncMaster 900IFT that I'd like to use with a BNC cable if possible, but when I hook it up I only get 640x480 as the available options despite the fact that my monitor works just fine with the standard 15-pin d-sub.

As the system is not able to detect the monitor capabilities over the BNC cable, it will use safe settings. You have to 'hard-code' your xorg.conf.

Please post the section device, monitor and screen of /etc/X11/xorg.conf as well as the make/model of your video card.

Make/model is listed under device, relevent section:

That should work in my opinion. Sorry, don't think that I can help you further.

It's no problem, it might have something to do with the open nvidia drivers (the video card doesn't work with closed drivers) and most people don't use BNC cables for their CRTs.

Just for the fun, try the vesa driver and see if that works. You can't get the 'extreme' resolutions, but 1024x768 should be possible with it.
