is there a way to set my graphics card output to 4k resolution? I have attempted to set it to do so in the system settings, but for some reason the highest it will go is 2560 X 1440. I recently bought a 4k monitor, and the graphics card is supposed to be able to support 4k output, I have all the recent drivers installed, and have the whole thing set up on an HDMI cable that should be able to support the resolution. is there some specific backdoor i am unaware of?
The R9 270 can do UHD and 4K via DisplayPort and via DisplayPort to HDMI 2.0 adapter, but as the on board HDMI port is 1.4, it cannot.
