I am unfamiliar with this concept. I am able to play games without the Display Port Cable hooked UP into the GPU. The Display Port Cable is hooked up to the motherboard. I am using "Asus ROG STRIX RTX 2070 OC". My Display Port Cable is connected to the Mother Board's Display Port. The "Motherboard" I am using is "Asus ROG STRIX Z390 F Gaming" and the "Processor" is "Intel Core I5 9600K". Can some one explain this to me.
