The standard cable channels or standard over-the-air OTA channels often appear fuzzy or blurry on your LCD TV because of a mismatch between the resolution capability of your TV and the resolution of the analog signal transmitted by your cable company or OTA broadcaster.
The signal you are getting from your cable company is a low definition i signal, with a resolution of approximately by It is this mismatch between the standard cable or OTA signal resolution and the TV resolution that causes the problem. Note: In many cases, even when you are viewing digital channels, the picture will look fuzzy. This happens because the signal your set is receiving, although digital, is a digitized standard i or p transmission, not a digital high definition transmission.
Again, you have the mismatch between a standard resolution picture and your high definition TV display. Use the Right arrow button on your remote to increase the sharpness. Press the Exit button to exit. Note 1: If your cable box doesn't have Component, DVI, or HDMI connections, contact your cable company to see if they have replacement boxes with these kinds of connections built in.
For instance, if stormy weather rolls into your area while you are watching satellite TV programming, the storm cell can interfere with the transmission, causing it to experience display issues. Accumulate snow on your satellite dish can also cause these types of problems, which are manifested in several ways, including digitized and blurry pictures.

In case you are using cable or source devices that cannot support 4K TV, your picture will come up blurry or not clear. To figure out the issue, check your current Netflix plan and settings because some plans allow streaming only in standard definition. Therefore, you cannot enjoy 4K Ultra HD streaming unless you upgrade your plan to an expensive one.
Also, you should check the playback settings of your streaming plan. But if you change the settings, it will be effective after a minimum of eight hours. But keep in mind that higher streaming resolutions can burn through data, and in that case, you will need a data cap. However, some cable systems provide up to p unless you are not paying an extra penny for HD. Also, note that some need a different box for the HD content, but some can remotely activate it from their office.
Therefore, make sure that your HD is activated and you are turning on an HD channel. First, check whether your Blu-rays display and online streaming are working fine or not. If those are correctly working and still your content looks grainy, then the problem is your cable.
It seems like you are displaying low-resolution content on a 4K TV, which supports high-resolution images. Your 4k looks grainy because the original signal of your cable is already in lower resolution. So, when your 4k system is automatically upscaling that lower resolution to the high resolution, it is becoming grainy.
