How to make HDMI work on TV

Through the following guide we will teach you how to make HDMI work on the TV if it does not transmit an image , solving most of the common problems in this type of connection.

How to make HDMI work on TV if it does not transmit image

There are some debates that talk about the differences and advantages between HDMI and DisplayPort , but the truth is that the HDMI connection is still one of the most important, at least in the world of television.

Indeed, the HDMI connection is available on practically all TVs , but it is not without its problems, one of the most common being that the image is not transmitted correctly. Given this, you can take certain measures that possibly help you solve this problem.

Verify that you are using the correct input

Since the emergence of HDMI output, more and more televisions include multiple inputs from this popular interface. In fact, today there are televisions that even include four or more HDMI ports.

On many occasions, it happens that the reason why the TV does not transmit an image through HDMI is precisely that we are not using the correct Input. In most televisions the HDMI inputs are numbered, something that is usually shown both on the rear panel (physically), and within the software or menu of the television, for this, we recommend doing the port check.

Check the health of your HDMI cable

Undoubtedly, this type of cable is very versatile, even allowing you to connect a mobile phone to a TV via HDMI . Even so, like any other type of connection, it is also prone to damage, which is why it can be damaged relatively easily in the event of a pull or improper treatment.

Understanding the condition of the digital signal, many times when an HDMI cable is damaged, it will not display any kind of image . In other words, when the video and audio signal is interrupted by a cable problem, no image will be transmitted. This is why we recommend you check the health of your HDMI cable.

Check for the correct signal

Televisions, like any other electronic device, have a range of operation, where appropriate, the screen refresh rate and resolution are usually the ones that define the capabilities of the equipment.

Although it is something “unusual”, the image may not be displayed on the screen as the TV does not recognize the signal . We point out that this is rare, since most televisions tend to indicate or display warnings of the type “Unknown video signal” on the screen.

In any case, it would not hurt to verify that the signal emitted when connecting your laptop to the TV via HDMI cable (or any other device) is correct for your type of television, both in frequency and resolution.

Disconnect and reconnect the cable

It may seem obvious, but many times unconnecting and reconnecting the cable solves the problem of missing image on a television. This is usually because the HDMI cable was not connected properly or simply because the computer or device did not recognize it.

By reconnecting, you will force the device that emits the signal to recognize the television, which in the vast majority of circumstances helps to solve the problem with the image.

HDMI is the king to transmit image on a TV

The truth is that the HDMI connection is essential today, in fact, there are some gadgets and devices that allow you to increase the number of ports or HDMI connections in SMART TV and many other very interesting functions.

It is because of the above that despite the fact that there are other alternatives , this type of connection is still the undisputed king in the television market and although there are certain common problems, as you will have seen previously, most of them are easily solved.
