Desktop did an in-place upgrade from Windows 7 to Windows 10 and since then, the HDMI output seems to be very intermittent.
Sometimes on start-up it works and then goes off after several minutes, else it fails to come on at all. Everything was fine on Windows 7
It is the AMD Radeon HD 7700 series with drivers 15.300.1025.1001 (11/29/2015) plugged into my Samsung TV.
Has anyone experienced this before and do you have any recommendations on how to resolve the issue?
