Hello, i've had a good search and google but i can't find the answer i'm looking for, but maybe somebody here can point me the right way

Well it started when i think i switched my mac off using the power switch (on the mac), and now the screen is too bright on one monitor and on my other completely blank. I am using a a quicksilver 733mhz G4 mac. Using VGA cable only, DVI-VGA adapter doesn't help either. I experienced something similar at work so i know it's not a display or video card problem, more something to do with the mac turning/sleeping on and off.

The display given is almost pure white on such as the system preferences window, so still legible but horrible. Any help would really be appreciated, and i hope to one day help those who i can

Thankyou
Frahz

System Preferences -> Displays -> Color Tab -> Pick a different [ColorSync] Display Profile. Or create a new one manually by clicking on the "Calibrate..." button.

Thank you for the suggestion, but the calibration is impossible to get right, for instance even setting everything to really dark folder icons on the desktop have a pure white light in the middle. However setting it like this has made it useable. All colours are still very wrong except very vibrant one's. From what i've read on the internet i think it may be something to do with monitor recognition when returning from sleep, or other power functions. Just a hunch though...

It's like i would say the monitors in some form of negative, RGB settings would seem to be the answer but i think it's in the RGB settings maybe that aren't visable from system preferences, maybe a driver issue.

If i can get the answer at work tomorrow i'll post it here, because there is another thread on macnn where i think the same problem has been raised but again no answer.

Take care, Frahz

System Preferences -> Universal Access -> Seeing tab -> Display: section -> "White on Black" radio button.

You can try the other options in that zone too, such as greyscale, and the contrast slider. This isn't a fix (it shouldn't be so bright) but it may help as a stopgap measure.

If that is not it, Frahz, then it is probably your monitor.
