If you’re having trouble seeing through your glasses, it may be because there’s something wrong with your eyes. If you don’t have any problems with your vision, you’ll need to figure out what’s causing the problem and get a new prescription.

1. Remove Sources of Interference

Some people have reported seeing LCD screen blur or ghosting when there is electrical interference or when their surge protector isn’t working properly. To fix this, try plugging your TV directly into the wall outlet without any power strips or surge suppressors in between. If that solves the problem, you can try using a different power strip. ..

If you have devices that use AC power, try turning them off on the same circuit as the TV. This will help to avoid electrical interference.

If you have fluctuating power coming from your mains, a UPS that filters out these spikes may be the solution, but you’ll need an electrician to check your supply.

2. Is Your Source Low Resolution?

A TV’s native resolution is the resolution that the TV was designed to use, regardless of the resolution of the image on the screen. A TV’s resolution can be increased by increasing its refresh rate, but this increases the cost and complexity of the TV.

A 4K UHD TV has a native resolution of 3840 x 2160 pixels. This is four times as many pixels as a Full HD TV at 1920×1080. So, for every pixel of information in a Full HD image source, the TV must fill four physical pixels’ worth of data.

There are various methods of “upscaling” lower-resolution images to high-resolution displays, but they all have varying levels of success. Going from FHD to UHD is straightforward since it involves making groups of four pixels act as a single pixel. Whenever the resolution of the source image divides evenly into the target screen’s resolution, you’ll get a softer image, but it will still look good. ..

If the source doesn’t divide perfectly into the target, you may get an ugly smeary result. Many of the fixes listed below can help to fix blurry or fuzzy upscaling results.

3. Change Your Upscaling Settings (Or Your Upscaler)

TVs and set-top box devices offer different ways to upscale sources to a higher resolution screen. Some devices have a built-in scaling feature while others require an external device. We can’t give you specific instructions because each TV and set-top box has its own features and menus. You’ll likely want to look in your manual or online for help with “upscaling” your sources.

TV upscaling can often improve the quality of your viewing experience by reducing the noise and distortion caused by the TV’s own image processing. However, if you have a low-end television, it may not be able to upscale well.

If you have a connected device like a cable box, gaming console, Android TV, Apple TV, or another similar source, set its output resolution to match your TV’s native resolution. Any upscaling will happen on that device before it reaches the TV.

4. Change Your Streaming Picture Quality Settings

If you are watching a streaming video source, the image may be fuzzy or have poor quality depending on your bandwidth and quality settings.

With some streaming apps, you can choose the preferred quality while watching your content. Change the quality setting from automatic to a setting that matches what your TV was designed to display.

If you’re using an internet connection that’s too slow to stream at your TV’s best quality, be sure to adjust your settings to get the best experience. There are different quality “bitrates” within each resolution tier, so even if your connection is at the lower end of the bitrate for a given resolution, you may still experience some artifacts and blurring.

5. Is the Source Digital or Analog?

HDMI is a digital image standard that ensures you get the source’s quality without degradation. If you’re using an analog source, such as a DVD player connected using RCA connectors, there can be a significant amount of interference or signal loss based on several factors.

HDMI is the best way to watch your DVDs and TV shows on a modern HDTV.

6. Try a Different HDMI Cable or Port

HDMI is digital, and it usually works correctly or not at all. However, if the amount of electrical interference or damage to a cable or port passes a threshold, it may degrade the image.

If the video is blurry or fuzzy, you can try swapping out the HDMI cable or moving it to another input on your TV to see if there might be something wrong with the cable or the port.

7. Change The Sharpness Settings

Most modern HDTVs offer a form of digital sharpening. This is usually listed under TV settings alongside contrast, brightness, etc. Use your TV remote control to access those menus, usually by first pressing the menu button.

If you find that your images look blurry or fuzzy when viewed on the display, it may be that the sharpness level has been set too low. To get a sharper image, you can turn up the sharpness until you’re happy with the result. ..

Some people prefer to increase the sharpness filter in order to make their footage look clearer. However, this can sometimes lead to an over-sharpened image that is not appealing. ..

8. Turn On Blur-Reduction Features

All modern flat-screen TVs exhibit a type of motion blur known as sample-and-hold motion blur. In addition, lower-end TVs may have inherent blur as the individual pixels change their state too slowly. ..

Some TVs that are old may not benefit from the new pixel response times offered by newer models, but companies like Samsung and Sony have worked hard to create new technologies to combat these issues. If you have an old TV, it may not benefit from the faster pixel response times more recent models can achieve.

The second feature is called judder reduction. This setting smooths out the picture by reducing the number of sudden changes in image quality. Again, different TV brands have different names for this setting, so you’ll have to look for something that refers to picture quality, smoothness, or do a web search for your TV model with the term “judder reduction.” ..

This feature creates new frames from the existing frames in the video to offer liquid-smooth blur-free motion. This is the much-derided “soap opera effect,” but you may prefer the crispness of this mode for some content, such as HD sports broadcasts.

The Black Frame Insertion feature on newer TVs is a way to defeat sample-and-hold blur by inserting a black frame between every frame displayed on the screen. This makes the TV offer motion closer to a pulsed CRT display, thus defeating the blur. However, this comes at the cost of brightness and vibrancy. Newer TVs don’t suffer as much as older models, but either way, you can switch the feature on and decide which image you prefer.

9. Turn Off Image Post-processing

TV manufacturers have a “secret sauce” of algorithms that help make images look better, but too much post-processing can leave a soft and blurry image. Too much post-processing can lead to an image that is soft and blurry. ..

If you want a clear and bright image without any post-processing effects, try turning off all of them using your TV manual as a guide. If you experience some blur or noise, adjusting one of the most important settings may be the best way to fix it.

10. Get a Professional Assessment

If you have a fuzzy, blurry TV, it might be time to have a professional tech support person look at it. In some cases, it may be as simple as replacing a relatively inexpensive component. But if there’s something wrong with the core components of the TV, it can often not be worth the expense to replace those major parts. Instead, have it repaired and replaced under warranty.
