“I bought this TV and it seems a bit grainy with my cable box. Did I get a bad TV or is this normal with cable boxes? I don't know if I am being too harsh or what. I am going to try upgrading my HDMI cable soon just to see.”

If online streaming and Blu-ray’s display fine, and it is only cable that is grainy, then it’s probably not a bad tv. You’re displaying a low resolution image (cable) on a high resolution tv. Essentially all cable is still 720p or 1080i (which is half the vertical resolution as 1080p) and it's generally compressed quite a bit in order to accommodate more channels. What you're seeing is due to the original signal being already pretty terrible and then upscaling that lower resolution content to high resolution 4K screen. You’re on the right track with trying an new HDMI cable. Look for one that is ultra high speed certified. It might help some with your issue. Also check your cable box settings to see if it is set to 1080 resolution. But in the end cable will almost never be as clear on a 4K tv as streaming.
Sorry, there was a problem. Please try again later.If you're on Xfinity you can get a 4k box that uses wifi instead of the coax cable and it will improve the picture quality . It'll say it's 4k but it also has to be 4k content to look it's best. But it still looks better than it did with my older cable box .
Sorry, there was a problem. Please try again later.One way to determine whether the problem is with the cable signal or the TV is to use the Roku native YouTube app and stream a 4K demonstration video. If that looks grainy as well, you may have a problem with the set.
Sorry, there was a problem. Please try again later.It's possible you have a bad set, but just as likely the cable box signal isn't up to par. If you have a 4K bluray player, it's worth trying to watch a movie and see if it is still grainy. Also, as you mentioned earlier... it's also possible you just have an older HDMI cable that can't handle 4K signal
Sorry, there was a problem. Please try again later.This may sound weird in 2020 but some cable systems have a resolution of 480p unless you pay extra for HD. If you pay extra then you get some content at 720p and 1080. Some require a different box for the HD content but some can activate it remotely from their office. Make sure you have the HD activated and that you are on an HD channel.
