I have the 4K Octagon plugged into a HDMI input on a SONY STR-DH750 RECEIVER and that plugged into the HDMI Input on the LG 4K OLED TV. When the SOUND volume is adjusted on the SONY amp, the TV picture blanks for about 5 secs then the sound mutes for another 2 secs and then both picture and sound return to normal. Touch the volume control again, the problem repeats. This only happens with the Octagon Receiver. I have Blue Ray player and a Vu+Solo2 connected to inputs on the amp and there is no problem with picture and sound loss. Octagon and Vu+Solo2 have OpenVix images and the settings in the HDMI CEC are the same. Both off. Have tried all the settings in the SONY amp HDMI settings to no avail. I don't have enough HDMI inputs on the TV to configure devices that alternative method. Can any one solve this annoying problem.

I have a Sony amp (different model) and a solo2. I have HDMI CEC turned on for all devices to operate correctly otherwise I would manually have to select whether to use amp/tv speakers as I dont use the amp all the time.

The Speakers in the TV I don't use. The Amp is used all the time because of better quality.

It sounds like your 4K aAVR, can not overlay in 4K (My Denon can't either), turn any onscreen messages (Volume overlay etc) off in the AVR.

You are correct its the overlay volume readout from the Sony amp. Mentioned in other places on the web. Sony need to provide a method of either turning off the volume overlay or update the receiver / Amplifier software.

To cure the problem was in the Octagon menu AV settings change the resolution out to 1080p. While this does not now deliver the full output resolution of the receivers capability, it fixes the problem I first posed in this thread. Also I have no satellites that are delivering 2160p resolution where I live. Where this receiver is still a plus, is that it receives DVB-S2x Multistream from Intelsat19 12569V content. A manual scan of the satellite will not bring up these channels but a specific TP scan with Multistream 161 etc will. My thanks to DaMacFunkin for pointing me in the correct direction.
