• I would suggest you try adding to your cable line to TV a signal amplifier. It may surprise and correct your lost signal. Cable does deteriorate over time.

• You need HDMI higher speed cables and of course your input source needs to have HD content. HDR and ultra HD 4K content looks the best, but 1080p content looks fantastic as well - like the display in store. Netflix and Amazon have HDR and 4K content.

• I was advised by the sales person to purchase an upgraded hdmi cable. I think was 10.00 and it sounds like it was totally worth it.
