How to Fix a Blurry TV Screen (STEPS)

Why is my TV screen blurry?

A TV screen can look blurry when the surge protector becomes faulty, an increase in electrical interference, or because of incorrect resolution settings.


  • Faulty surge protectors
  • Electrical interference
  • Resolution mismatch
  • Incorrect settings
  • Damaged HDMI port or cable
  • Activated digital noise reduction feature
  • Incompatible cable box


A damaged HDMI port or cable, an activated digital noise reduction feature, or an incompatible cable box can also cause a blurry TV screen.


How to fix a blurry picture on my TV screen

You can fix a blurry picture on your TV screen by replacing the faulty surge protectors, eliminating sources of electrical interference, and correcting the resolution settings. You can also use a different HDMI port or cable, turn OFF the digital noise reduction feature and use a compatible cable box.


  1. Remove the surge protector connected to the TV and connect it directly to the wall outlet. If the blurriness stops, the surge protector is defective and needs to be replaced.
  2. Remove sources of interference such as fluorescent lamps from proximity to where you have connected the television.
  3. Adjust the resolution of the content so that it matches the TV resolution. You can use one of the various methods to transform images of low resolution into high-resolution displays.
  4. Check for incorrect TV settings such as low sharpness levels that tend to soften the image. Raise the sharpness filter until you find that the picture is no longer blurry.
  5. Connect the TV to a different HDMI port or use a different HDMI cable for the connection. If the problem gets resolved when you do one or both the changes, it means that either the port, cable, or both were damaged, which triggered the blurriness.
  6. Check if the digital noise reduction feature has been activated on your TV and turn it OFF. This setting can at times affect the picture quality. You might also consider turning ON the blur reduction feature.
  7. Make sure that the specifications of the cable box, as well as the TV, match each other. If you have an HD TV but the cable box doesn’t offer HD support, you must get a cable box upgrade done.
  8. Minimize the possibility of glare by switching OFF the lights in the room and closing the curtains. The glare can cause the picture on the screen to appear blurred.


Why does my 4K TV look blurry?

Your 4K TV looks blurry due to low-resolution content, incorrect TV settings, an incompatible cable, incompatible source devices, or insufficient bandwidth. The blurriness may also be because the home mode has not been set.

  1. Use the 4K TV to play or watch 4K content. You can download the 4K content onto a USB drive and plug it into the TV for viewing the content. The blurriness typically occurs when you try to watch low-resolution content.
  2. Check if your TV settings have been done properly for viewing UHD or HD content. If they haven’t been done, getting those settings activated should solve the problem.
  3. Replace the cable used to connect the 4K TV and source devices with one that supports a 4K connection. If the cable doesn’t support the connection, there is a good chance of blurriness. If you’re already using a 4K cable, make sure it isn’t damaged.
  4. Make sure that the source devices connected to the 4K TV support 4K. If not, they will not be able to decode 4K videos, making way for blurry images. You can also ensure that your streaming services render 4K UHD support.
  5. Ensure that the TV broadcasts have sufficient bandwidth to display 4K content. If the network connection isn’t strong enough, you may likely encounter blurriness.
  6. Change the TV settings from store use to the Home mode by pressing the Home button on the remote control and accessing the Settings

Why is the text on my TV blurry?

The text on your TV is blurry because of aliased text, a turned OFF game mode, or outdated software. A panel issue can also cause blurry text.


  1. Check if the anti-aliasing feature in your TV has been turned OFF accidentally and turn it ON. If the feature has been deactivated, it can cause the text to appear blurred.
  2. Turn ON the game mode on your television. This mode will often remove any post-processing of the picture and text by the TV and produce clearer content.
  3. Check for any pending software updates of the TV and do it at the earliest. This will often eliminate the blurriness of the text when the 4K TV receives its 4K 120Hz input signal from a different device.
  4. Get the assistance of the technician to look out for a problem with the panel of your television. Depending on the problem, you can get the panel either repaired or replaced.


Why is my TV blurry around the edges?

  5. Move surround sound speakers or subwoofers near the television to a distance of at least more than 10 inches away from the TV.


Why is my TV blurry during dark scenes?

Your TV is blurry during dark scenes because of a resolution mismatch or an activated optical picture control (OPC) feature. The dark scenes are also likely to appear blurry if the backlight has been turned OFF.


  1. Upgrade the cable box if the cable service resolution is lesser than the default TV resolution. Often, HD TVs have a resolution of 1920 x 1080 while standard cable boxes offer a cable service resolution of 640 x 480.
  2. Do a check if the Optical Picture Control feature of your TV has been activated under Picture Settings. If so, turning it OFF will most likely solve the problem.
  3. Check if the Backlight setting has been turned OFF and activate it. This may help you to fix the issue of a blurry effect during dark scenes.


If none of the above helps, you can always do a factory reset to resolve the problem.
