Sky uhd on sky box has stopped working, it will not even recognise 1080p on my TV

[AJ1969a]

I have been watching uhd on my sky q box running through a denon amp into a panasonic tv with no issue for a few years, Today went to watch some UHD content and it said my TV could not show this. I have rest the sky box, tv and amp to no avail. I have connected the shy box directly to the TV with the sky supplied hsmi yet it will only output 1080i.  Anyone have a similar issue

HI @AJ1969a 

I have not had a similar issue so can't give any specific advice.

Perhaps double check the TV HDMI 4K mode setting on the relevant HDMI just in case it has somehow changed

Also - clutching at straws - I ssggest giving all the equipment (TV in particular) another full power down restart  (switch off at mains/unplug)

Hi @AJ1969a 

Have you checked that the Denon Video 4K signal format is still set to Enhanced?

[AJ1969a]

I have checked the denon and tv all are set as usual. I have directly connected the sky box to an hdmi socket using the link ended hdmi cable to rule out any issues with the amp and it's cabling. Not supporting UHD is bad enough but not running 1080p is more surprising

You probably have but have you tried a different HDMI cable ?

[AJ1969a]

Yes run it on 2 seperate hdmi cables on differing hdmi inputs as well

Hi @AJ1969a 

If you have carried out a Reset on the Q box have you checked that it is still set to 2160p resolution in Audio Visual settings?

[AJ1969a]

Yes, I rub the set up for 2160 10bit, 2160 8bit and 1080p neither of these will show anything but a blank screen.

Hi @AJ1969a 

When you set the Q resolution to 2160p are you getting the confirm screen before the setting times out?

[AJ1969a]

Yes, it gives me the confirm/cancel options but just a grey screen behind with no image
