I have a KVM or External monitor (19″ Dell) that I am trying to hook up to a laptop running RHEL 6.3 (via VGA which is the only option). When I connect it, and go to System->Preferences->Display, the max resolution option it provides me for these external devices is 1280×1024. Now, the KVM should provide a maximum resolution capability of 1600×1200, and the Dell monitor should have a capability of 1920×1080. Neither of those come up. How do I get this to work? I was reading online that Red Hat OS needs to be configured for the graphics card on the laptop in order to provide higher resolutions. I would hope it’s simpler to this. Any hints or tips?
