Running Solaris 9 with an XVR-1200 video card. I cannot get the card/monitor to display at 1920x1200x60 even though that should be supported by both card and display. I ran prtconf and get the following:

SUNW,XVR-1200, instance #0
display, instance #1 (driver not attached)
pci, instance #1

I run fbconfig -dev /dev/fbs/jfb0 -res \?. All of the results come back with a [1] after them indicating it is not a supported resolution. If I try to set it to 1920x1200x60 which is supported by the monitor, I get a black screen. I have reloaded the video driver and that did not help.

Any help is greatly appreciated

Take a look at patch 114555-36. May or may not help.

The OS is telling you it isn't supported - by the OS.
