My AMD card is set as default, but windows doesnt detect my monitor
This is very frustrating.
I have a Radeon HD6450 on my desktop pc, and a monitor which is plugged into its VGA output. I installed windows 7, and it installed and ran fine, but it didnt have the ati drivers, so the resolution was low. I installed the windows updates, including the ati drivers. When I restarted, the windows loading screen displayed, but when it finished the screen went black. After a bit of research, I think the problem is that the radeon card is switching output to DVI:
Computer doesn't start up after Catalyst install... what's wrong? [Archive] - AnandTech Forums
Unfortunately, I dont have a DVI cable to test this, and I dont want to buy one if I dont need to.
To get into windows I need to go into the bios and set the onboard graphics to be the default graphics, and connect my monitor to the motherboards VGA output.
I can then connect a second monitor to the Radeon's VGA output, and windows detects it and all is dandy, except I have to use onboard graphics.
Does anyone know why my Radeon card is switching to DVI on startup? Catalyst control panel didnt seem to have any relevant settings..
Thanks!
