ThanksHave you considered using remote play? Will be a bit of a problem to setup initially if you don't have a spare HDMI screen but afterwards should be fine:

Took a few pictures of remote play vs wired direct to TVEDIT:WOW the PS4 picture across remote play looks really rubbish compared to what it looks like when connected directly to the TV, Looks like what an old movie looks like or something..
