It is a technology that allows devices to connect audio, video and sound files in high definition. In the practical case of tablets, the idea is to repeat on a larger screen, such as an HD television, the digital content that we see on the tablet or on a Smartphone, can be movies, You Tube videos or your own videos. That being the case, the user experience improves, it is more fun and it is easier to share your photos and other multimedia files without losing quality in the images.
However, to connect your tablet to TV via HDMI, it is essential that both devices have this type of connection, that is, that they have an input to connect the cable that contains the interface that facilitates communication between both devices.
On the other hand, the HDMI cable also has its specifications. There is a 19-pin connector, type A, which is the most widespread and another 29-pin connector, type B, which is designed for resolutions greater than 1080p (larger images).
In turn, so far its developers have launched several versions of the HDMI cable: 1.0, 1.2, 1.3, 1.4 and 2.0, each has added improvements to the previous one, higher transmission speed, higher resolution and more supported devices. In this sense you should know that, at least for now, the most used version is 1.4 and that it is compatible with the previous ones, that is, if you have purchased a 1.4 cable and your TV is compatible with version 1.3, no You need to buy another cable because the later ones (1.4 and 2.0) will be compatible.
Keep in mind that the manufacturer of your tablet probably markets its own cable, it is more likely to be more expensive but you will be sure that it will work well. A universal cable, preferably approved, is usually cheaper and will be fine if you buy the appropriate one.
Many HDM I cables have a mention of their category. This refers to the image quality depending on the length of the cable. A category 1 cable is suitable for short extensions (for example 5 m), but if you need a longer cable, you must select a category 2 cable.
Another important aspect is the format of the HDMI input of your tablet that can be full-size or HDMI, medium-sized or Mini HDMI and the smallest is Micro HDMI . This information can be found in the specifications of your device.
Steps to connect the tablet to the one TV
- Go to Settings of your Android tablet and click on Screen and activate the HDMI connection , sliding the button to the right to where it says YES and turns blue
- On your TV, connect the cable to its respective input and then locate the source list on the screen and choose HDMI .
- Connect the other end of the cable to your tablet and you should repeat what you see on your tablet on TV. In some models nothing is seen on the tablet.
- You may need to complete more settings, such as setting in Settings / Display / HDMI and there the resolution and transmission speed. For example: 1280 x 720p at 60 Hz. Actually the entire process will not take you more than five minutes.
The benefits of HDMI are diverse. The first, in my opinion, is that the image quality is maintained in high definition. It is also a cheaper alternative than external accessories such as Chrome cast, Roku and Apple TV.
Although it is true that in the market there are HDMI cables of 65 euros / 80 dollars, it is also true that with one of less than 20 you can have excellent results.
