Why Does My 4k Tv Look Blurry? It’s Probably Your Screen Refresh Rate!

Why Does My 4k Tv Look Blurry

When it comes to TV resolutions, 4K is probably the most talked-about one. Thanks to a growing demand for UHD content and affordable 4K TVs, more and more people are buying these products nowadays. However, even though the 4K resolution is by far the most sought-after one, it doesn’t mean that every TV with this resolution will look good. Sure, some models have great picture quality and viewing experience as a result of their high resolution. But if you’ve ever bought a 4K TV before and ended up being disappointed by its blurry picture quality, rest assured that you’re not the only one who has experienced this issue. There are many factors that can affect the way your TV looks when watching content in 4K resolution. If you want to see the true potential of your new purchase, follow this guide about what to do if your 4K TV looks blurry or how to make it look clearer without spending too much money on additional equipment or software.

Why Does My 4k Tv Look Blurry?

There are a few potential reasons why your 4K TV might look blurry. One possibility is that you’re not watching content that was specifically created for 4K TVs. In order to get the most out of your 4K TV, it’s important to watch content that was filmed or produced in 4K resolution.

What Is A 4k Tv Resolution?

1. 4k Tvs Have 4 Times The Resolution Of Full Hd Tvs.

The number of pixels in a TV’s display determines its resolution. The more pixels, the clearer the picture will be. In other words, a 4K TV has an ultra-high number of pixels that are four times higher than those found in a Full HD TV.

2. 4k Tvs Have A Resolution Of 3840 X 2160.

The most common resolution for UHD TVs is 3840 x 2160, which means that it displays a video image with 3840 horizontal lines and 2160 vertical lines. This is how all UHD TVs display their content: they will use either two or three full-width columns of this resolution, depending on the model. For example, if you buy an LG 55EC9800 (a 55-inch TV), it will be able to display Ultra HD pictures with at least 4K (3840×2160) resolution, but it will use three full-width columns of this resolution on its screen.

3. 4k Tvs Have A 4:4:4 Pixel Ratio.

The most common way of displaying content in 4K resolution is by using a 4:4:4 pixel ratio. This means that each pixel is made up of four sub-pixels, which allows the TV to display images with great detail and clarity even when it’s viewed from a distance, thanks to its high resolution. The drawback is that you need to position your TV close to your face if you want to see the best picture quality possible.

Why Does A 4k Tv Look Blurry?

1. Your Tv Is Not Calibrated

Let’s start with the basics. If you want your TV to look good and have a good viewing experience, you need to calibrate it. This step is important for two main reasons: first of all, you will be able to get a better picture quality than you would on a TV that has not been calibrated. On the other hand, calibrating your TV will also help improve its energy efficiency. If the image on your screen isn’t accurate, the less power your TV will consume while displaying the image.

2. Your Screen Refresh Rate Is Too Low

When it comes to 4K TVs specifically, a high refresh rate can improve the clarity of images displayed on the screen by increasing their responsiveness and sharpness. Unfortunately, this technology is not available on every 4K TV model yet as manufacturers are still trying to figure out its optimum settings in order to achieve the best results for their customers. However, if you want your 4K TV to look good, you’ll have to figure out how to change your screen refresh rate so that you can enjoy better picture quality.

3. Your Tv Is Connected Through Hdmi 2.0

This is another important factor that can cause your TV to look blurry. When you connect your 4K TV to the internet through an HDMI cable, the speed of the data transmission between your TV and the source device (computer, smartphone, game console) will be limited to a maximum of 1.4 Gbps. The higher this number is, the blurry your screen will look as a result of its lower resolution and reduced frame rate (the rate at which it refreshes). If you want to improve your viewing experience and make sure that your 4K TV looks good, you’ll have to change the type of HDMI cable that you use or find an alternative way to stream content from a device to your screen without using an HDMI cable at all (for instance, by using a Chromecast).

4. Your Tv Is Not Connected To A 4k Source

If you want your 4K TV to look good, you’ll have to connect it to an HDMI input on your HDTV set or a 4K-compatible source device. This means that you’ll have to buy a 4K signal receiver (for instance, the Sony STR-DN1080) or a 4K Blu-ray player (for instance, the Sony BDP-S3700). Unfortunately, most modern TVs don’t support this type of technology and therefore cannot display content in true 4K resolution. If you want your TV to look good and have access to an HDMI 2.0 input, consider buying a new model that supports the protocol.

Change Your Screen’s Refresh Rate

  1. Screen Refresh Rate. The refresh rate is the measure of how often your TV’s screen displays a new image. When you first turn on your 4K TV, it takes time to read the content on your 4K Blu-ray player and turn it into an image that can be displayed on your TV. For example, when you play a movie in 4K resolution, the playback signal of this movie is sent to your TV and immediately turned into an image that can be seen by your eyes. This process takes time, so it’s normal for the screen to look blurry when you first turn on your TV. But after a while, the screen will become clearer and clearer as the refresh rate gets faster and faster.
  2. Changing Your Screen’s Refresh Rate: If you want to see how changing the refresh rate affects your picture quality, go ahead and try this test yourself: Switch off all lights in your house except for one light source that is directly above your TV. Turn the TV on, then turn off the light source. Then change the brightness of your TV to a level that makes it impossible to see any picture whatsoever on your TV. Next, turn on your 4K Blu-ray player and play a movie with 4K resolution in it. The movie should look blurry and distorted as if it’s being played through a bad projector. But after you’ve turned off the light source again, you will notice that every image on your TV is perfectly clear as if you’re watching it in a bright room.
  3. Why Doesn’t My Screen Look Clear? The reason why your 4K TV looks blurry is because of its refresh rate (see point #1 above), but this isn’t the only factor that can affect how your screen looks when playing content in 4K resolution.

Adjust Your Tv’s Video Settings

  1. The first thing you need to do is to adjust your TV’s video settings. This is the most important step in fixing your TV’s blurry picture. The default setting for most TVs is the ‘automatic’ mode, which usually has a certain level of sharpness and contrast applied to it. You can try turning this setting off and use another one instead. For example, you can try ‘Movie’ or ‘Dynamic’ modes which are specifically designed for watching movies on your HDTV.
  2. If you’re still having issues with your 4K TV’s image quality, switch your TV’s HDMI input back to the same one where you had connected it previously (if there is more than one input available). Most TVs have a button that allows for switching between inputs easily.
  3. If all the above steps haven’t worked, then you might have some sort of problem with your TV’s refresh rate or its refresh rate settings. If you have a 4K TV, then chances are that your refresh rate is 60Hz. If it’s not, then you will have to check your TV’s manual to find out what the refresh rate is in your specific model. If you find that it’s not 60Hz, then there is a chance that the problem lies in the TV’s internal circuitry or its processing power. You will need to take your TV back to the store where you bought it from and ask them for help.


Although it’s true that a 4K TV has better resolution than Full HD, not all of them look crisp and clear thanks to the type of screen that you have. If you want to make sure that your new 4K TV stops looking blurry, make sure that you pick the right TV type for your needs. In addition, make sure to change the refresh rate of your screen if it’s 60Hz, adjust the video settings to your liking and add hardware to boost the picture quality. If all of this fails to make your TV look clear, it means that you have a model that has inferior screen technology. There’s nothing you can do about that, so you should just pick another TV with better screen technology.
