I read somewhere that there was a way to quick switch between 1080i and 4K(it’s better for your tv to do the scaling on normal he content) on SkyQ but I can’t remember where does anyone know how it’s done
The easy way to switch from 2160p to 1080i is just press HOME 1 0 8 0 HOME on your remote.
When you select a UHD file/programme, the box should prompt you to switch to 2160p using the red button. When finished use HOME 1 0 8 0 HOME to go back to 1080i
Sadly if you are not given the prompt, or miss it, there is no easy switch to go from 1080i to 2160p; you have to change it via the picture settings, to do this use:
Settings > Setup > Audio visual -> Picture resolution
