Set up a new Hitachi 4k TV today.
When I change to Netflix via virgin then try to get back to the TV I lose signal. Also on start up it takes a while to find the signal.
Using a hdmi cable straight from v6 box to port 1 of tv
Yes. I've moved the hdmi cable from port 1 to port 2. Seems to be working fine now. And still in 4k
