When I use the AMD Radeon RX 580X 4GB to setup an HDTV and use it as a second monitor, my GPU gets really hot, and I'm not doing anything intense, just browsing (70-80 celcius).
That's why I want to use the onboard graphics for the HDTV and leave the GPU for my Acer H236HL monitor. However, when I went to the BIOS I could not enable the onboard graphics and btw there is a plastic cover on the back of my N50 covering the motherboard HDMI.
FYI, my CPU is an i7-8700...so it does have integrated graphics capability.
Is there any way to enable onboard graphics or it just cannot be done?
