My screen has changed?

Question

It has set itself at 4 bit when it should be 64 bit. When I click on it it will only give me the option to go as high as 32 bit. When I click apply nothing changes. Helppppppppppppp!

I did that twice but still nothing. I have even updated the drivers for the NVIDIA graphics card but that didnt help either.

Answer 1

try lowering your resolution....some higher resolutions might not support higest color setting or refresh signals

if you hit advanced settings you can select "list all modes"

Answer 2

Have you changed the screen driver to one that doesn't understand the card's capabilities?

Has your video card suffered a hardware failure and lost a chunk of it's memory?

Is your video card sharing memory with the processor? Have you changed how much memory it's allowed to have? If it's not got enough memory to run your resolution at 64-bit it won;t let you select it.

And do you have an anti-virus scanner? I've seen odd 'hardware' misbehaviours caused by viruses accidentally changing bits of memory that were not used on the writers PC but are used by something on the (different hardware) on the infected PC.

Answer 3

Are you trying to make the canges with windows or with the nvidia tool. Sometime going to control panel will not allow me to make changes either. I have to open the nvidia tool and make the changes there. Hope it works for you. Otherwise, try rolling back the drive and see if that helps.

Answer 4

Its your display drivers - install the latest drivers for your graphics card...

Answer 5

Answer 6
