The reason why the projector cannot display full screen
1. The phone displays a vertical version of the screen: if the picture is displayed, the projector screen projection screen vertical vertical version is also natural that there are about blank, can not fill the full screen;​
2. The resolution of the computer is inconsistent with the projector: when the computer is connected, because the resolution is inconsistent with the projector, the full screen cannot be covered;​
3. The projection ratio is inconsistent: the current projection ratio of the projector is generally 16: 9 or 16:10, if The projected computer is not at this screen ratio, so the projector cannot be full screen.​

Solution of making projector adjust the screen size of full screen (connecting computer)

Step 1:
According to the different types of projectors, there are generally two main interfaces for connecting to the projector, one is VGA and the other is HDMI. First of all, we need to see which type is directly connected to the corresponding interface of the computer. Here we take the Fangbei projector F1 as an example.

Step 2: Generally, it will automatically adapt to the projector at this time, if not, please do it manually. Right-click the mouse on the desktop and select the full screen resolution (the projector has many resolutions, such as 1024X 768 if it is high-definition then the resolution is 1920X1080)

Step 3: In the window that opens, choose to connect to the projector.

Step 4: After connecting the projector, the mode is usually selected by default to copy, that is, the content displayed on the computer and the projector is the same. If not, you can choose to manually copy.

Step 5: If the size of the projection does not match the size of the projection screen, you can adjust the projection size by setting the resolution of the computer. Click on the resolution to make adjustments.

Step 6: Generally, after the adjustment in Step 5, you can basically adjust the size of the computer put on the projector to fill the entire projection screen. If there is still a little deviation, it can be adjusted by setting the zoom and displacement of the projector segment screen.

Step 7: disconnect the cable directly. After setting the computer, the next time it is used on the same projector again, it can generally be adjusted full screen automatically. This is the case with the projector used by the editor. Others may vary due to different models.
