Configuring an Ultra 60 to use a Flat Panel Wide Screen Display

I recently decided to upgrade my display from an old 21" Sun CRT monitor to a new flat panel wide screen display. I found out that the Ultra 60 Creator graphics adapter was unable to detect the graphics modes that are supported by the new monitor. The monitor simply displayed "Signal not Supported". I figured that I needed to experiment with various graphics settings to find one that worked. Finding the information on how to do that was more challenging than I thought it would be. After some digging, I found out that "ffbconfig" is the tool that configures the Creator card. I had a remote ssh session to the server and ran the command while I watched the output on the console. Using some trial and error, I was able to find a setting that my monitor would accept. You can run "man ffbconfig" on the command line to see a list of the settings that the Creator is capable of setting:

1024x768x60
1024x768x70
1024x768x75
1024x768x77
1024x800x84
1152x900x66
1152x900x76
1280x800x76
1280x1024x60
1280x1024x67
1280x1024x76
960x680x112s (stereo)
960x680x108s (stereo)
640x480x60
640x480x60i (interlaced)
768x575x50i (interlaced)
1440x900x76 (hi-res)
1600x1000x66 (hi-res)
1600x1000x76i (hi-res)
1600x1280x76 (hi-res)
1920x1080x72 (hi-res)
1920x1200x70 (hi-res)


After some experimenting, I found that 1024x768x60 works on one machine that I have. Another seems to prefer 1152x900x66. I don't know why the two machines seems to work with different resolutions, but at least I have them working now.
