The quality during normal viewing is absolutely fine but when using apps such as netflix and prime, the menu quality is absolutely horrendous. When watching 4K or HDR video through netflix or prime the quality is perfect. But anything in the menu or only HD the quality is really poor.
Thanks for getting in touch, and welcome to the Community Forum! I'm sorry that you've had some problems with your new 360 package.
Could you just expand on the problems that you're having a little bit more? What kind of picture issues do you have when viewing programmes in HD/viewing the menu screen? Does this issue always occur, or is the problem occasional/intermittent?
