So, I have an AMD RX 570 GPU with only one output (DVI). It was originally made for mining so that would answer why it only has 1 output. My CPU has an integrated GPU so I wanted to use that for dual monitor, however the PC just doesn't detect the iGPU. I checked in BIOS to see if there's any option regarding the iGPU, but I couldn't find anything.
How can I enable the iGPU?
