I have a 30" monitor that is currently in the shop for repairs. I've gotten a loaner monitor, but it's saying the sync is too high. (It's 1600X1200). I've tried zapping the PRAM / NVRAM, no go; same problem. Then I unplugged the machine, pulled the battery, (had to pull the video card to get at it) and waited two minutes. Same problem. From what I've read, the NVRam is supposed to store the monitor resolution, so resetting it would hypothetically clear the issue. I'm wondering if there's some other trick here I haven't found yet. Any suggestions? Thanks very much.
