Mac mini at work will not display colours that are less than 20%
They just display blank.
Tested in quark and photoshop.
Tested with a different monitor.
Tested with different monitor cables.

What should I do? Is it an applecare job?
Its a Intel Core 2 Duo 2.0ghz.

What do you mean? What is less than 20%?

The Mini uses the Intel GMA950 for graphics. Check to see whether any 950 machine can do this. I wouldn't trust the 950 for anything graphical.

A friend of mine uses his single-core Mini for his (quite successful) web-design business. He's never reported any problems with colors. It may be something with your specific machine. If you can replicate, then take it back to Apple.

I don't know anyone using the Mini, so I can't help you check, sorry.

Which monitors? DVI or VGA?

Have you tried calibrating your monitor or makes sure you are using the correct profile?

If DVI and LCD are those 6 bit LCDs (many TN models) or 8 bit LCDs (more of the higher end, S-IPS stuff).

Make an appointment with the Apple store and show it to the Genius. They should be able to fix or swap it out if it still is under warranty.

Sorry I meant less that 20% opacity.
These are VGA CRT displays.
Yes the other intel mini displays it fine.
