Yup. This really needs to be fixed. There have been on-going bug reports on it for years. AMD just needs to move the hdmi 2.1 stuff behind a firmware binary blob already like NVIDIA does. It's so annoying not having full quality HDMI. It's the only think keeping me from using Linux on my current gaming PC that is hooked exclusively up to my TV... Either that or TV's need to start having Display Port.
