On most channels the picture quality is blurry and rubbish when in full screen but when I press home on the remote so the screen is small in the top right corner, the quality turns crisp. How do I make it the same quality for in full screen?
It is a V6 box and I have a Hisense Roku Tv which is 4K, I’ve followed the settings to get the best quality but it doesn’t seem to work unless the screen is in the top right hand corner or when I’m watching BT
Lastly, go through the troubleshooting site here to see if this resolves the issue - Help Website.
However, I have already taken the time to check your services on my side and I could see straight away that your TV box is out of spec. There are Pre RS Error Counts that are causing your problem which will need an engineer to rectify.
I will be glad to book this in for you today via a PM, which I will send over now 🙂
