Win10 projection HDTV

  • by

In the era of light office, many people already use mobile phones, tablets and other devices for office work. After connecting to the network through wireless projector, smart phones, tablets, PCs, and TV screens can realize multi screen interaction. The large screen is used to browse pictures, documents, and PPT, which is very smooth compared with direct projection and app projection, The response speed of the connection delay through the wireless projector is much faster, and the delay is basically not felt. Of course, the specific situation depends on the network environment.

There are several ways to project the content on PC to HdTV

1. Wired connection via HDMI cable

Operation steps:

1. First of all, connect the HDMI interface to the computer first. It’s better to turn it off or not, but it’s better to turn on the TV after connecting it;

2. Then connect the TV;

3. After connecting the cable, turn on the computer and TV;

4. Switch the TV signal to HDMI.

According to the above operation, after the TV is switched to HDMI, the computer will display what the TV shows. At this time, the TV becomes a computer screen. The HDMI audio will start automatically, and the sound is sent out from the TV instead of the computer. So you can watch the movie on the big screen.

Comment: HDML cable needs to be arranged, which is inconvenient, which is why modern wireless projection is the main reason.

2. Connect through app, box, etc

At present, most app and TV box can project the content from PC to TV, such as aiyiqi a, Tencent, Youku + TV box. Generally, app is equipped with a box for online projection. The principle is also very simple, that is to send the link to the box, where the TV is just a display screen.

Comments: various copyright issues. Many users may say that I don’t care. I just need to be able to cast the screen. But because the projection app and TV developers do not let you use it for the sake of copyright? Another one?

For example, at the beginning of April this year, there were conflicts between kangaroo remote control (defendant) and Youku (plaintiff). Behind this lawsuit, it was actually a step taken by the screen casting app, which touched the thunder pool of the copyright owner. On the surface, it’s a problem between the screen casting app and the developer, but it also has a great impact on users. For example, the mobile version of LETV no longer supports direct screen casting by opening the website. The announcement gives suggestions: users with screen casting needs need to download and jump to the third-party video client for screen casting; And the commercial version charges.

Apple’s airplay-2 is a representative in this respect, signing agreements directly with TV developers. Like that. Support copyright and respect content creation.

Connection steps:

Use steps (take Leebo as an example, the rest of the apps are roughly the same)

Step 1: install the PC version and TV version of LETV respectively for the computer and TV (projector)

Step 2: connect the computer TV to the WiFi of the same LAN, and the computer can plug in the network cable

Step 3: first search the connection, and finally select the mode you want to cast

3. Wireless projector

Wireless projector is a third-party device. However, it avoids the shackles of HDML cable, does not have copyright problems, and meets the needs of business meetings. Some people have expressed such a sigh: only image clone projector is a channel for data exchange with mobile phones, tablets, PCs and display screens.

Connection steps (take awind Qiji products as an example)

1. Connect the Qiji product with the display screen (TV screen, LED screen).

2. The signal port of awind strange machine is inserted into the computer (the pigtail is connected through USB)

3. Drive awind strange machine Icon on the computer screen.
