Many newer TVs tout 4K resolution as one of their primary features. This resolution often helps to increase the image quality and showcase additional details. You may ask yourself, “how do I know if my TV is 4K?”

One of the differences between HD and 4K TVs is in the resolution. 4K TVs have four times the number of pixels than their HD counterparts. This means that they are capable of producing sharper images with more detail. Additionally, 4K TVs offer a wider range of colors, resulting in richer and more vibrant images.

There are a few different ways to find out, including the box the TV came in, in the owner’s manual, in the settings section, or by attempting to watch 4K content. You may have gotten the best TV in the market, but you need to first confirm if it is 4k.


  • 4K TVs provide increased resolution compared to high-definition (HD) TVs.
  • To determine if your TV has 4K, you can look at the packaging or manual that came with the device.
  • If that doesn’t work, you could try to play 4K content and see if it shows appropriately in 4K.

What Makes a TV 4K?

Lately, more TVs have 4K displays, or sometimes even 8K displays. So you may be wondering what is a 4K TV and why is it important. You can check out our comparison of 720p vs 1080p to see how 4K stacks up to the models that came before them.

4K refers to the number of pixels available along the horizontal axis. These TVs include roughly 4,000 pixels linearly and millions in total. The “K” stands for kilo, just like kg stands for kilogram.

4K TVs contain a resolution of 3840 × 2160, with each number indicating the number of lines of pixels there are. This makes for a viewing experience that is four times better than the 1080p resolution of a standard HDTV. 4K TVs also have increased video output, allowing you to enjoy more realistic and lifelike visuals on your screen. With an ultra-high definition viewing experience, it’s easy to see why 4K TV technology has become so popular in recent years.

This number means that there are 3,840 rows by 2160 columns with a pixel at every grid intersection. And if you notice that your picture quality isn’t as nice and crisp as it should be, you may be experiencing clouding.

In fact, LG Nanocell TVs are designed with their own special anti-clouding technology that can help reduce the amount of clouding in your picture. So if you’re having clouding issues, you can read this article on how to fix clouding on an LED TV.

4k has precise image details

4K TVs are considered ultra-high definition (UHD), which also includes the resolution of 8K TVs. In some places, the resolution of 4K may be called UHD TV1, while the 8K resolution is called UHD TV2. 4K is here to stay, and 4K TVs and content will likely soon be as commonplace as HD TVs and channels. 8K features increased image quality and details compared to 4K, but these TVs cost significantly more. Most of them are often smart TVs that can allow you to watch TV without cable.

Check the User Manual

When you buy a new TV, most of the vital information you want to know can be seen on the outside of the box. However, consumers may throw out that box not too long after unboxing their TV. If you retained your TV box, you should find out whether your TV has 4K by looking at it.
