I dont want to mess up your for sale thread but video cards with DVI out, have 4 pins built in the connector for an analog RBG signal. So you just need like a $1 adapter :lol
The idea behind that thing is to use with consoles with HDMI and a tv or monitor with analog inputs. If you have an older tv/monitor that’s the only way you can play in hidef. Eh, someone might need it, I know I won’t.
