I have a Radeon R9 390 running on Windows 10. The primary output is DVI to a monitor and the secondary output is HDMI to a 4k television.
This has worked but recently the secondary output is no longer being detected.
There is no issue with the cable as I can see an output during the PC boot up process, during safe mode and if I fully uninstall AMD drivers from my system.
Once I re-install my AMD drivers I once again lose secondary output.
The secondary output(tv) is detected within the Radeon console it just does not display to it.
Any help would be greatly appreciated.
