I'm trying to install Red Hat Linux 7.3 on my PC. Probably not a good idea, since I know nothing about Linux or Unix.

All goes well until it gets to the bit where I have to set up my monitor. It doesn't have my monitor (Iiyama AS4612 TFT) listed, so I selected "undetected monitor" and entered the correct horizontal and vertical refresh rates.

When I click "test" to see if my settings work, they don't - I get a scrambled image.

The monitor is connected to a GeForce3 Ti via a digital connection. Does it need to be connected via analogue or could something else be the problem?
