Last week I upgraded to Telus 4K. While actual 4K programs look incredible, now all the other channels look horrible (and of course the majority of shows are not in 4K). The picture is very grainy and blurry, and some are so bad it looks like it's from an old VHS tape. I've tried every setting I can think of, and have Googled for days for an answer. Nothing has worked. Any suggestions?
Unfortunately, no matter what I set it at, the picture is still terrible. I had no idea Hisense had an issue with upscaling. In fact, when I bought this $650 TV 2 months ago, I didn't even know what upscaling was. I just assumed a 4K TV would display 4K programming, and not make non-4K programs look terrible. Thanks for the info though!
If you set the Optik box to 4K output your TV will not need to do upscaling. As far as your TV is concerned all channels are 4K because the Optik box does the upscaling before sending it to the TV. When I watch a HD or SD channel the TV input on my Sony still shows as 4K.
If HD channels look worse than HD then there may be something wrong with your Optik box. Have you tried setting the Optik box output to HD and watching a HD channel? This will bypass any scaling on the Optik box and let the TV scale up to 4K. Does it look any better?
