|Yes, it's a 65 inch Samsung.|
But any mainstream brand 4K TV like Samsung should do a great job with 1080P.
Really? Well, then the explanation provided by the cable guy doesn't make any sense, he said the TV wants 1980p and can't do 1080p all that well.
What are the video sources you are using, and how are they connected?
Our issue is with the cable signal. For example, if we watch CNN on cable, the CNN logo is a bit blurry.
DVDs, video games and immediate digital connections are great. HD cable signals are very good. But "normal" cable signals (such as CNN) are not as good as one would expect with a high end brand new TV.
