Users are still having a lot of issues with HDMI cables, so we decided to do what we always do and lend a helping hand.

Recently, we’ve shown you some neat ways to fix your HDMI if itโ€™s not allowing 144Hz, so we thought we should give you some more HDMI guides.

A lot of users are complaining about receiving error messages saying that HDMI is not compatible with the signal, which is what prompted this article.

That being said, if you are having this problem, relax, sit back, and take a few minutes to learn how to deal with it properly.

Keep in mind that the HDMI not compatible with this signal is not only an error for PC users, and you can also experience it on your Smart TV.

What does it mean when HDMI is not compatible with this signal?

In a nutshell, the TV may not support the same higher resolutions that your computer monitor might, but they’ll almost certainly support resolutions that are much more acceptable.

So, we recommend verifying that the source device has power and is turned on before you go ahead and try anything else.

If the source device is connected with an HDMI cable, make sure the TV and source device are both turned on, then disconnect the HDMI cable from one of the devices and then connect it again.

What can I do if HDMI is not compatible with the signal?

1. Manually switch the Input source

It should go without saying, but sometimes the solutions to what seem the most complicated problems are actually simpler than you might have imagined initially.

Whether we are talking about your monitor or your TV, make sure to press the Input or Source button and switch the input source to the HDMI port.

One more thing to keep in mind is the fact that, if you have more than one HDMI port, be sure to select the right one.

2. Unplug/replug the HDMI cable

As we said, the simplest solutions can sometimes prove to be the most effective ones, so before we go further with the troubleshooting, please also consider this.

Again, whether we’re talking about a TV or a PC monitor, simply unplug the HDMI cable from the back, leave it out for a couple of minutes, then plug it back in.

Many users have actually mentioned that the problem disappeared once they unplugged and then replugged the HDMI cable.
