I'm not sure if video-only ports like HDMI still exist on Gaming PCs in the future. I feel there is a chance that in many years most newer PC monitors and video cards would use USB-C or other forms of USB ports and cables to connect a Gaming PC to a newer PC monitor.
But, I feel it may take many years for video-only ports like HDMI to be gone from Gaming PCs because there will still be many people with older HDMI monitors.
