I have an external graphics card and onboard one, but pc seems to ignore completely the onboard one. If I connect my monitor vga to it nothing works, onboard also accepts hdmi but if I connect hdmi to a tv nothing works either (even after restart and all those things applied).
Do I have to remove the external card for pc to start using the onboard one? Is there a less messy way such as maybe updating some bios settings or using some software?
Both cards are ati radeon.
