Getting 4K Resolution on a Samsung TV

To get a 4K resolution on a Samsung TV, you first need to go into the settings of your television. Go into the television menu section by pressing the menu button on the remote control.

From there, you want to go to settings and then display settings, Within the display settings, you should see the resolution option for the television.

You want to choose a resolution known as Ultra-High Definition or UHD. If you just see the numbers of pixels, the 4K resolution is shown as 3840 x 2160.

In order to get the 4K resolution on the Samsung TV, you also need a device to send that signal of that quality.

If you are playing on a Sony PlayStation 5, for example, you need to go into the settings of the console to choose the output to be that resolution. The same goes for a cable box, streaming player, etc.  

The final piece of the puzzle is the HDMI cord. Not all HDMI cords are high-quality enough to be able to support the transmission of a 4K signal.

In order to get the 4K signal to your Samsung TV, you need to have the cord to support the process.

When you are purchasing your HDMI cable, be sure it is high enough quality. If it is not then the television will now show it in a 4K resolution, but instead, the signal will go down in quality.

How to Tell If a Samsung TV is Displaying 4k?

So how can you tell if your Samsung TV is actually showing in 4K resolution? There are a few different ways to run a 4K test.

The first way to do that is to check the resolution. If you see the resolution on the television is 3840 x 2160, then you are seeing everything in 4K.  

You can also check the resolution on the screen if you are working on a Samsung TV display with a computer.

On the desktop of your computer, you can go into properties and then display properties. Once there, go into settings or graphics options and you can check the resolution.

Why Won’t My Samsung TV Play in 4K?

What are some of the reasons why your Samsung TV will not display in full 4K resolution? There could be three different problems you may be facing.

It could be the television itself, the HDMI cable, or it could be the device sending the signal.

For the television, it could be that your Samsung TV is not capable of showing a 4K resolution. When you go into the settings of the television you will be able to see the different resolution options.

If the resolution open is there to show things in UHD, that means the television is capable of doing a 4K resolution.

If you do not see that as an option, then you do not have a 4K television. You will need to upgrade the television to get things in 4K.

You also want to look at the HDMI cord. The HDMI cord may not have the capability of transferring a full 4K signal from the device to the television.

Try a different HDMI cord if you are running into trouble with your Samsung TV showing in 4K.

Finally, you need to check out the device sending the signal. If your video game console, for example, is not capable of playing in 4K, then the television is not going to show 4K quality visuals.

It may try to upscale, but it will not be true native 4K resolution.
