I have been using my Gaming computer to produce platform content, Rumble. As an assist I have connected to a Sony TV for monitoring and extended video recording via HDMI cable. It has been working fine up until a day or two ago. First I lost the audio, but now I am receiving a "no-signal" message on the TV. I have connected a separate computer to the TV to test the HMDI cable and it is working find so the problem is not with the TV or the cable but with the computer I am using. Any suggestions? I have run diagnostics and all systems appear to be operational.
