- bestouff 5y agoI think it doesn't support more than HDMI 1.4, which means 30Hz @ 4k.
- ralferoo 5y agoWhat I found is that the TVs support HDMI 2.0, but at least a few years ago even the high-end graphics cards only did HDMI 1.4, and so couldn't drive at both 4K and 60Hz, even though they were able to support the same over DisplayPort. Fortunately, dongles are relatively cheap, so this shouldn't be an issue. The problem I had using such a dongle is that there seemed to be bugs in the Radeon driver, unrelated to the graphics mode, where it wouldn't always redraw the contents of some windows, and if you dragged the window around, the left-over garbage was moved around. And for some reason, these problems didn't affect either 4K at 30Hz or 1080p at 60Hz. In the end, I just switched to nVidia and put up with possible YUV fringing effects instead. I'm sure in the maybe 5 years since then, that the bug has been fixed now.
