I recently bought an R7 370 to drive a new 4K display.
The problem is, I can only get it to work at 30Hz.
You can see in the attachment, anything above 30Hz is unavailable.
It's too slow even for mouse movement.
Lower resolutions are of course all right.
I emailed the manufacturer, PowerColor, and they recommended to download the latest driver for the card.
Maybe, they say, the card does not support 4K 60Hz.
I replied and asked point blank, please tell me if this card supports 4k@60Hz, what do you mean "maybe"??
So, does it, or does it not? I bought this card for that purpose alone, I don't play games. I want it for documents and schematic development.
Any help will be appreciated, thank you.
