My LC630 has recently decided that it won't display in millions of colours anymore - the highest it will do is thousands

Maybe it heard it was about to be dumped infavour of a G4?

Any help would be appreciated.
600 x 480 resolution; 36MB RAM; Ram Doubler

Remove all your Preferences from the Preference folder in your system folder. Restart. After restart go to your monitor control panel and set it to millions. I am surprised, did not know that model could do millions.

If that works then it is a bad preference, if not, restore every thing back to the way it was, it is another problem.

I am unfamiliar with the mechanics of the 630, but if it has removable VRAM, and you USED to have millions of colors, reseat or remove/clean contacts with a pink pencil eraser/reinstall your VRAM module(s). However, according to Apple Spec Database, max VRAM is 1MB(non-removeable) and max resolution at 640X480 is 16 bit(thousands)and it is right about 99% of the time.

The Apple service manual sez it can do 16-bit at 640x480 and 8-bit at 800x600....
it also sez it has built in 1mb VRAM which is not expandable

Thanks everyone for your help. I could have sworn that it used to do the full colour thing but now I have ordered a G4 I won't be using the 630 for much longer

thanks again

My old Performa LC 575 developed a similar problem a couple of years ago. It would no longer do 16bit graphics, only 8bit or lower. The problem went away when I upgraded from Mac OS 7.6 to 8. You may want to try the dump the preferences fix, or reinstall appropriate video drivers.
