Hi, I just bought a Sony PS4 Pro and have it connected to my X65 TV via HDMI. It seems there is no signal passing between the two machines and so I tried to plug the PS4 to another TV and it works fine.

I checked up on the internet and found some contents related to compatibility issues between PS4 and LeTVs. In addition, I also tried some "solutions" suggested on the internet like enforcing HDCP1.4 and lowering the output resolution from 4K to 1080p. However, none of these works and nothing could be shown on X65, not even I could enter safe mode of PS4. Everything I tried another setting I need to connect to another TV.
