my monitor has 3ports:1 analog,1 dvi,1 hdmi .I plug top r290 to dvi port with dvi to hdmi adapter and plug the igpu to hdmi port.After i start pc with igpu windows 7 saying there are no amd drivers installed and they dont work
I found out to install properly the amd drivers the igpu needs to be disabled. So disable it, reinstall amd drivers, see that everything works, then enable again. On 2 of my computers had to do the same, no idea why.
