How Do I Know If My TV is 4K? All You Need to Know (2023)

Televisions with 4K resolution are quite popular right now. The other day, I started to question whether my TV was 4K or not. There isn’t much to choose between a 4K and HD TV when it comes to picture quality. Do you know whether your television is 4K?

Examining your TV’s manual or packing box may tell you whether it’s 4K and what resolution it has. In most cases, the resolution is referred to as “Ultra-High Definition” (UHD) in the user manual.

3840 x 2160 is another way to express it in pixels. You may also see ‘4K’ displayed in bold text style instead. As indicated in this article, you may use various ways to confirm your product’s legitimacy and quality.

What is a 4K Resolution or UHD?

Most people are familiar with SD, HD, and UHD or 4K resolutions since they’ve seen them on a variety of television sets. These pixel sizes range from 720p for SD to 3840p or 4096p (about 4000, thus the term 4K) for UHD, depending on the format.

It’s a measure of how well-done your photo or video is. Increasing the number of pixels in your picture or video allows you to see even the smallest things in crystal clear clarity.

You would assume that this implies 4K TVs are huge, but there are a number of excellent compact 4K TVs available that have excellent pixel density and clarity.

What is the Difference Between 4K and UHD?

This is a question I’d want to address from two perspectives:

  • You need not be concerned as a customer. The 4K TV you bought is really a UHD model. Nevertheless, except for the tiny change in nomenclature and resolution, the two are almost identical.
  • The 4K format, on the other hand, offers a resolution of 4096 x 2160, which is exactly double that of Full HD!

UHD might be compared to HD and SD on content platforms, although 4K is more of a production industry word. In the case of a UHD (almost 4K) device, the aspect ratio is often 1.78:1 to guarantee that the product reaches to market with an attractive aspect ratio.

Other Methods to Check If Your TV is 4K As previously said, an excellent place to begin is with the handbook or package box. A smart TV that has access to YouTube will be of great use to you in this situation. Go to the official GoPro Action Cameras channel, for example, which has a lot of visually appealing material.

You’ll have no trouble locating material that’s accessible in a variety of sizes. Personally, I’d suggest starting at a lower resolution and working your way up to 4K. Yes, provided the network is not a problem, you will quickly notice an increase in content quality.

You won’t be able to use the 4K option if your TV only supports standard HD since certain devices restrict the quality to the highest levels that can be shown. You may also use your television’s remote control to access the display’s information.

If you have a Smart TV, your remote control, for example, should include an info button. As soon as you press it, the pixels and format of your TV’s display will be shown in the upper right corner. Images or even simple text may be used to evaluate the image’s quality.

Aside from looking at text corners, there are a few more options worth considering. Font corners and edges will look like little square boxes at lower resolutions because of this.

How To Watch 4K Content?

1080p 1440p and 2160p

You have a wide range of choices here. I can think of a few that are well known and readily accessible.


There is a lot of 4K stuff to be found here if you want to look around. You can get 4K footage for trip documentaries, action camera videos, and certain movie trailers.

All you have to do is choose the ‘quality’ option and enter the information you need. It’ll say 2160p with a 4K superscript in the resolution field.

Streaming Services

For the time being, all new Netflix releases will be in 4K quality. You’ll have to pay a monthly membership fee to use this feature. On Amazon Prime, you’ll find exactly the same thing: You can also watch movies and other media on Apple devices.

You’ll be able to get them via Apple’s iTunes store. There is a cost associated with using the platform, and that is indicated on it.

4K UHD Blu-Ray

A Blu-ray player, which costs around $100, is required. Any Blu-Ray movie in 4K format may be found at a neighborhood Multimedia store or online purchasing platform once you have a Blu-Ray player in your possession.

Many more platforms can provide 4K video besides these few. We’ll go through a few of them in more depth, along with cost and content information, down below.

Can You Watch Non-4K Content on Your 4K TV?

Even while it’s technically feasible, it’s not recommended. I’ll do my best to make the concept as clear as possible. More pixelation occurs when a picture is stretched to suit the screen size rather than resized. With this rule, you may use any number of different resolutions. As previously stated, a 65-inch 4K TV should have an average screen size.

It is possible to get a television set that is up to 80 inches wide. A poor-quality picture that looks OK on a 16-inch screen may seem far worse when stretched to fill the whole screen, so be careful when attempting to show poor-quality images.

However, there is a workaround for this issue. Upscaling is the phrase used to describe this process. Now, it’s important to keep in mind that upscaling will never significantly increase the quality.

However, material that has been upscaled will always be superior to content that has not been scaled. Image processing is required for upscaling, and as the original content’s resolution decreases, the procedure becomes less effective.

Upscaling a 1080p video to 4K is always preferable since it’s faster and simpler than upscaling a 720p video.

How to Make The Most Out of Your 4K TV

How can I make the most of my 4K television now? Selecting the right accessories or addends for your TV set is the quickest and simplest solution.

Sony, Samsung, and others make smart 4K TVs that are commonplace in homes today. Instead, you may use a dongle or a nice streaming stick if your TV doesn’t have an HDMI connector. You may learn how to make your TV smart by following these instructions.

If you’re having trouble deciding between different streaming services, go back to the table at the beginning of this post for help. To avoid problems with backlight distribution on LCD TVs, go for newer display versions like the OLED when buying a new TV.

While installing your TV, another option is to put it in a location where most people can see it and watch the program material while you work.


You may verify your TV’s resolution format from the handbook or the display settings on your remote to see whether it is 4K or not. Secondarily, you may utilize free streaming services like Youtube to distinguish between video resolutions of 144p and 2160p (4K).

Copyrighted 4K video may also be found on subscription-based services like Amazon Prime and Netflix. Look at the corners of an image or text to see whether the visual quality is acceptable.

Getting the greatest image out of your TV set is simple now that there are so many tools and video streaming platforms accessible online and on paper.
