Whilst all the options for display settings are available and appear to be working there are no colour reds in them. I have tried all available options:
16-24-and 32 bit settings but still get only greens yellows and blues but no Reds. Could anyone please help me? bearing in mind that I am still somewhat of a novice at this.

Hi and welcome to D-A-L

is it the monitor that doesn't show any reds?

have you tried a different monitor or this monitor on a different machine?
