If you find that your Windows 10 OS is not recognizing your 4K TV, you must know that this is a common issue amongst users, and it can be fixed.

Using your 4K TV as a monitor for your Windows 10 PC offers you the capability to display more items at the same time if you’re working, or to watch your favorite TV shows and movies online.

Getting this setup to work shouldn’t be too hard but sometimes a small glitch can make it seem like a never-ending problem.

The reasons for this issue happening can vary a lot. It depends on the setup of your PC, how good the HDMI connectors of your laptop/PC are, and if you’re using the right Windows settings to allow this to work properly.

In today’s fix article we will explore some of the best fixes that will allow you to connect your 4K TV to your PC and use it as a monitor. Read on to find out more.

Here’s what to do if Windows 10 is not recognizing your 4K TV

Even though this method might seem obvious, in a lot of the cases we researched online it seems that the issue was caused by a faulty HDMI port.

In order to try this out, you will need to remove the HDMI cable from the HDMI port you’re using now and plug the cable into another port.

2. Change the HDMI cable

If the above-mentioned method didn’t help, it might be that your HDMI cable is damaged. HDMI cables can get damaged easily while being transported, or the connector of the cable might get clogged with dust particle.

To try this, get a new HDMI cable and connect it to your Windows 10 PC and the 4K TV.
