1. How to wirelessly connect a desktop computer to a TV

I am taking the computer at home and the LCD TV in my bedroom as an example. If we want to connect the computer to the TV If you get up, first check the video interface of the LCD TV. We removed the TV and saw a VGA interface, as shown in the picture.

Let’s move the host again, and we see that there is a VGA interface on the main graphics card of the host. Please note when connecting the computer to the TV, because the resolution of the TV is higher, it is best to use a discrete graphics card. Generally, some older integrated graphics cards may not support connecting to a TV. As shown in the picture

Our computer is connected to the TV. If it is a desktop computer, a host computer, mouse and keyboard must be prepared. VGA cable, power cable. Because the desktop computer must recognize the keyboard when starting it, of course a mouse must be used for convenient operation. We plug the VGA cable into the host's independent graphics card. Also connect the power cord, keyboard and mouse.

Then plug the VGA cable into the VGA port of the LCD TV.

In fact, if you connect it like this, don’t think that the computer and TV are already connected. This is just a connection of images. If you want to connect audio, as shown in the picture, we see that there is an audio interface on our LCD TV interface, which I circled.

If you want to use headphones, you can plug them directly into this interface, but it is recommended that you use longer headphones, 5 meters is recommended.

If you want to use the TV's speakers directly, that is, let the TV play the audio directly. You can buy a male-to-male audio cable, as shown in the picture, plug it directly into the audio interface of this TV, and plug the other end into the audio interface on the back of the host. I recommend buying one from Akihabara.

After connecting, we turn on the TV and the console. We saw a blue screen on the TV and no signal.

Let’s get the remote control and press the video signal selection button. What we saw before was the video signal input. That is the signal input of the digital set-top box.

We choose computer signal input.

We see that the connection is successful. Everyone operates just like you would on your own computer.

If the computer is connected to the TV, I still recommend using an HDMI cable. If your TV has a high-definition interface and the computer also has an HDMI interface, you can use a high-definition cable to connect. This kind of access does not require another audio cable, just one cable. The video signal is much better. It is recommended to use Akihabara. If the distance is longer, you can buy a longer HD cable. Then use a wireless mouse, the effect is very good.

The second type of WiDi:

Use Intel's WiDi technology to achieve wireless connection between laptops and TVs, provided that both devices need to support this standard.

Among them, notebook products must use Intel Core series processors, built-in Core series integrated graphics cards and dedicated wireless network cards. Currently, the number of such notebooks is relatively abundant. You can judge whether it is by checking the notebook configuration sticker. support.

As for the TV, if it cannot support WiDi, you can choose to buy a product like the D-Link wireless display adapter to add functionality to it. Generally speaking, the threshold for WiDi is still relatively high.
