Need to reset color-depth of display...

Hi there,

recently my computer crashed (while working in Adobe After Effects). I made a cold restart and since then the color-depth of my display is forced to 256 colors (or sth like this, I did not actually count them). It looks coarse and ugly.

I find no option in my system-preferences (which is strange as there should be an option?). I tried to force the color-depth to "Millions of Colors" using a third-part-app "SwitchResX" but nothing changed. I've tried to find a command-line for setting the color-depth in Terminal but couldn't find the appropriate command-line (I'm also not an expert, honestly).

Because I can not work in a color-depth like this I installed a new user on the computer and color-depth is fine when I'm logging in as the new user. Nevertheless I would like to restore the color-depth of my old user-account, as I don't want to set up all menu-settings and system preferences, etc... for the new user-account again...

Any ideas what I could do?

Thanks in advance,

aeiou
 
Hi MisterMe,

thanks for the response. I'm using Mac for 14 years now and for sure I know System Preferences / Displays. I usually also calibrate my monitor, so I am not totally inexperienced.

Anyways: for some strange reasons there is no "Color Depth" in the preferences for the display nor anywhere else. Changing the calibration doesnt change the color depth.

Also: System Profiler shows that monitor would show "Millions Of Colors" (which it doesn't).

Also: Font smoothing doesnt work.

Also: after logging in the monitor shows the normal color-depth for a split-second before suddenly switching into 256-color-mode.

What's wrong?

Thanks for your help, aeiou

Funny thing is also that when I connect via vnc: (screen sharing) then the monitor color depth on the connecting computer is actually normal.
