Uhd no longer working

[Wheresmy5ghz]

Started up my sky today to find there was sound but no picture.  I managed to reset the resolution to 1080p and it's working ok, so for some reason the picture @ 2160p is now not available on my LG TV oled c7

Have tried rebooting and checked most recent software update is running on both TV and sky q box.  Checked with my firestick and 4k still works ok on tv

Uhd has always worked up to now so not sure what the problem could be?

Have you tried a Different HDMI cable if you have one @Wheresmy5ghz ?

That's a great shout.  Bypassed my AV receiver and 2160p is working again.  Looks like it's a hardware/cable issue with the receiver

So it turned out be a software update was needed for the AV receiver.  All done and working now, thanks again for your help
