I have one HDMI entry on my pc. I just bought a new screen and he's using my HDMI entry. I just tried to use an usb3/HDMI adapter for my old TV screen that's usualy using my HDMI entry. But the image is just crap for an 100$ tool. So I thought I could run two graphics cards or replace the current one. I could buy a better card but buying the same that I have is less expensive and I dont need to increase anything aslong has my screen is passing by an HDMI entry. So i want to know If it's possible and how. I think the physical building might be simple, but do I use another driver or a special one.
Big thank you to anybody that can help me.
