Why Is My 4K TV Blurry & How to Fix It

A 4K TV is a TV set with 4K resolution, a display device or content of 3840 x 2160 pixels. We can watch streaming programs on the native TV channel or play external videos via USB. During the playback, we can adjust the TV settings such as picture mode, brightness, backlight, color, etc. However, improper settings may make the TV look blurry, grainy, or fuzzy. There are many reasons why 4K TV looks pixelated, including but not limited to the following:

1. You are watching low-resolution content on the 4K TV.

If your video resolution is lower than 4K, pictures on your 4K/UHD TV will show up as a blurry mess. Meanwhile, all 4K TVs don’t have components that can upscale videos from 1080p or other resolutions.

2. The cable is low in quality, or the source device does not support 4K.

Sometimes, the grainy picture on 4K TV happens when you connect your 4K TV with a cheap or low-quality HDMI cable. Moreover, if the source device, like TV box, connected to the 4K TV cannot recognize 4K content, there will be no 4K pictures on the screen.

3. The 4K TV does not upscale 1080p to 4K but only makes the picture bigger.

When you play a 1080p video (1920 x 1080 pixels), the 4K TV will force the display in 3840 x 2160 pixels. Then, you will get a bigger yet blurry picture on the TV.

4. Your TV settings for UHD content are incorrect.

TV settings like brightness, contrast, hue and tint can also affect the video display. If you have recently changed any of the settings, try reverting them to default values. You can refer to the official suggestion to get the best effects on your 4K TV.

5. You need to upgrade or buy a new 4K TV.

There are many TV brands, and you can choose LG, Samsung, TCL, Hisense, Sony, Vizio, etc., based on your preference.

Based on the possible reasons why a 4K TV looks pixelated above, we can repair the blurry movements on 4K TV with the following methods:

1. Use a device that supports 4K videos.

2. Use high-quality HDMI cables.

3. Set up 4K TV settings properly.

4. Upscale video to 4K resolution to fit the TV size.

Since all 4K TVs lack supporting components to upscale 1080p content, you need a third-party video scaler to fix 4K TV blurry issues caused by the incompatible resolution.
