8/10 mbits setting is in the Sky Q box itself - make sure that the HDMI lead is the correct one.
TV doesn’t accept 10 mbits, it has to be 8.
Try changing the settings on the Sky box whilst it is in HDMI 2 then plug in to HDMI 1
If you haven’t used HDMI 1 before it will detect a new connection and ask you to set it up.
This can also be done by the menu on the Avant too. But the key is to change it to 8. And as you can see it on HDMI 2 as non 4 K then try that.
But I thought 1-4 do 4 K since that update a while back. Will have to check the FAQs
