I have a new monitor and i am using Digital and it disables the auto adjustment settings on contrast, brightness, gamma etc. How am i suppose to manually configure all these to get it looking good? Is there some way i can auto adjust it?

I have tried changing the brightness , contrast and gamma on the nvidia control panel too but its just too hard to get it looking right.
