In my device manager, my pc only detects my GPU which is the gtx 970. I am planning to use HDMI connection rather than DVI for my computer to monitor. HDMI only works when I configure in the BIOS making the primary adapter is the onboard or the integrated gpu, but the problem is that it doesn't detect my dedicated GPU. So I reverted my primary adapter back to PCI Express which is my dedicated GPU, and tried enabling iGPU(integrated GPU I think???). Well I managed to make the HDMI working, and both the HD Graphics 4000(integrated) and the GTX 970(dedicated). However, when I start to play Crysis 3, it uses my integrated gpu. I tried changing it through the Nvidia Control Panel, but there was no "Preferred Graphics Option" to force it to use the GTX 970. Soo yeah, am I doing something wrong or one of the methods I did is supposed to work? Or is there really no way to solve this?
