Are you experiencing fuzzy images on your TV? Well, if you are wondering why your top-rated TV is fuzzy, it can be a result of several issues, from the type of cable service you are prescribed to the condition of the wiring. However, while your cable service quality may be subject to weather or distortions affecting the image quality occasionally, cable wiring issues may affect your viewing experience in the long term.

KEY TAKEAWAYS:

  • Fuzzy images on the TV are caused by a mismatch between the TV default resolution and the standard cable service resolution.
  • Cable TV services provide low-quality 480i, which is approximately 640 by 480. Modern Television units have a resolution capability of up to 1920 by 1080 or more.
  • Most HDMI and DVI inputs in the market don’t accept standard analog signals (480i).

Fortunately, fixing a fuzzy TV isn’t something that requires technical experience. However, some of the tasks may involve restarting your set-top box, replacing your coaxial cable, or tightening connections.
