I just bought one panasonic 65" TH-65AX900H. But i found a problems which may related to HDMI handshakeing issue in 4K signal . i connect a pioneer bdp-Lx88 bluray and denon avr-x7200w to it . when i set video output of pioneer bluray player and denon avr-x7200w to 4K (50/60). Sometime, i got a flashing picture . it is similar to the attached youtube video .
I had changed another HDMI cable such as audioquest carbon HDMI (5m long) and audioquest (vodka) 3m long . Both of them are claim for HDMI 2.0 . but this problems is still happening. I also update the latest firmware of this TV, bluray and denon AV amplifier. it seem that this issue still cannot be solved. But when i set the output setting of bluray player and denon X7200 to 1080p or 4K (24/30) .. the problems are seem to be solver...
Do anyone own this TV has the same problems with 4K (50/60) video input..?
Please advice what problems is it ? Thank you very much
