1 server had an old CRT style monitor. We have an asus vw220s that we would like to use on that server. When I physically remove the CRT and install the flat screen, there is no display. Get an out of range error on the monitor. I put the CRT back in place and tried to change to the new screen in yast->hardware->monitor but asus vw220s is not listed. What is the correct way to install an different monitor on sles11?
