I've had my PS4 since launch and I don't have the best TV but it does 1080p just fine, but since the 2.01 update I can't use my PS4 on my main TV as it continually flashes unsupported mode and cuts to a second of video then back to unsupported mode. Now I've tried running the PS4 with different HDMI cables different ports on the TV and nothing. I've tried using remote play on the vita and everything displays fine there. It plays fine on my bedroom TV where I set it to 1080p resolution locked instead of autodetect (an issue I had on the Xbox one when I first got it) and still nothing on the main TV. Whats even weirder is I plugged it in through the Xbox One and the video came up just fine. ANyone have any idea what in the sam hell is going on here?

I don't have an answer for you but you are not alone. I thought my HDMI ports were going bad.

1) Is it headed straight into the TV?

2) Are the fancy colour depth etc options set to full/automated/off?

3) Is it a TV that can get its firmware updated via USB?

I'd like to use my PS4 with a HDMI splitter and even with HDCP disabled it's worse than ever. Lucky to get something not a black screen ever. How old is that TV, what make and model? Consider #3 that's what I have to say.
