I recently bought a 4k display that does not have a DisplayPort port. All along I thought that my Radeon R9 270X would support 4k at 60hz, and I can set those settings in Catalyst Control Center, but no matter what I do, the display only receives a 30hz signal.
So I finally realized that the 270X does not support HDMI 2.0. Right?
Will it be possible to add that with a new driver? Or do I have to get another card to use the display at 60hz?
