Try booting off a CD-ROM. From there you could try changing video resolution using the control panel on the Harddisk.
I think I have found the problem. I zapped the PRAM, as Clark suggested, with the 7600 hooked up to the NEC monitor, using an adapter. No change. I then hooked up the Multiple Scan 20 monitor (no adapter needed), zapped the PRAM, and I had many choices. I also noticed that the control panel said "Multiple Scan Display"). I hooked up the NEC again, and it looked good. I decided to restart to see what would happen. I was back to 640x480 only, and the control panel simply said "Display".
I think the adapter to go from the 7600's DB-15 to the NEC's HD-15 is the problem. It's a simple one, with no DIP switches to set. Do you think a better adapter would solve the problem?
Thanks again.
Wade
