I purchased a 26" LCD display to work with my G5 machine.
All is great and I am very happy, BUT there has been an annoying problem with the Mac not reconizing the right resolution of my new LCD (which is 1920x1200)... As a result, every time I did a restart, the LCD remained BLANK. When I turned it off and on again, I would get a scrambled jumpy image, like a monitor which is out of sync. The message I could barely read was "out of range"... It took 2 more restarts (safe-boot included) to set it right. This same procedure went on time and again whenver I did a restart.
Apple was of no help ("this is not a Macintosh problem, you need to check with the display manufacturer" the girl with a heavy Indian accent told me)...
Thanks to one excellent member here (ToastyX) I resolved the problem by doing a ZAP THE PARM procedure, which is a (not very kown) Macintosh trick for "curing" Macs that behave erratically...
So, if you're a Mac user, getting a new LCD display, once you connected the display, start up with Zapping the PRAM: once you push the botton to boot up -- hold down these 4 keys: Command+Option+P+R (you need both hands) and wait for the startup "gong"... I always keep my hands on those 4 keys for another 2-3 "gongs" and then when the last "gong" sounds, I let go and allow the Mac to go on with the startup process...
It cured my problem. So I thought I'd share it with you, fellow Mac user....
