Hi I have the Sony STRDN1060 amp with SKY TV connected to the SAT HDMI port and PS4 connected to the GAME HDMI port. I also have a Jamo C9 Center channel speaker with two additional speakers connected left and right. The amp is connected by HDMI to a 49 inch Sony Bravia KD49X8309 TV. The SKY TV works fine and the sound is fantastic but when playing the PS4 I lose the picture for a split second and then it comes back. This seems to occur approximately every 90 seconds. I have tried the following: Different HDMI cables Different HDMI ports Updated firmware on my TV, PS4 and amp CEC was already turned off My TV is not 3D so I can't turn off 3D detection HDMI cables are HDMI with Ethernet and are good quality. For the problem to occur like clockwork it makes me think there is some optimisation running causing this interference. Any suggestions?
