1.Please prepare a VGA or HDMI cable and an external display screen in advance.
2.Connect the external display screen to the computer using a connecting cable.
3.Use the combination keys “win”+”P” to set the display mode.
4.There are four display modes available, and you can freely switch between the computer and the TV according to your actual needs. Firstly, you can directly connect the computer and the TV through an HDMI cable. Secondly, if the computer is a Win10 system, you can connect the computer and the TV to the same network. Right click on the file you want to project and select Play to Device to achieve screen projection.
Chromecast – The most reliable method. If you find using cables troublesome, you can try Chromecast.

2.Open a new window in the browser and click the ‘Project’ button.
3.Finally, when the laptop detects an external device, search for the TV and click to make a selection.
4.This will successfully connect the computer to the TV.
Although Chromecast is great, as it operates through WiFi, if the WiFi environment is not good, there may be delays or low image quality.
Miracast – The most popular method. If you are not satisfied with Chromecast, I would like to recommend another wireless connection method – Miracast technology.
1.Go to computer settings and click on ‘Devices’.
2.Next, select ‘Connected Device’ and click ‘Add Device’.
3.Wait for the computer to complete detecting the device and click on your TV from the available options.

Although Miracast has made significant breakthroughs in connectivity, there are still some issues. Firstly, it cannot be continuously displayed, and so far, no one has come up with a solution. Then, there may be some delay between the computer and the TV. Finally, it cannot support multitasking.
