I have a curious problem with my Quicksilver, which is powered by a dual 800 Mhz card (thank you again Fury). The video card is an ATI Radeon 9000 Pro. I run MacOS 9.2.2 on one partition and Mac OS X 10.5.8 on the other. Until tonight I used a cheap Vizio LCD (model: um-d24hnd1) and was able to boot back and forth between both systems without any problem. Tonight I hooked up an LG HDR 4k (LG27UK-850W) and, while I was able to boot into Mac OS X just fine, but every time I tried to boot into MacOS 9 I ended up with a gray screen. I zapped the PRAM, tried to change the resolutions, ran disk utility diagnostics, etc. but to no avail. I still can not get MacOS 9 to show on this LCD. Any suggestions? Thank you very much.
