When the WIN8 computer is connected to the projector, you can quickly press the keyboard "Win+P", and the right side of the desktop pops up "Projection (or called The second screen) & rdquo; function, you can select the display mode in the "only computer screen", "copy" & rdquo;, "extension", "only second screen".

We focus on "extension", which is also a function that many people don't understand. "Extension" can reduce the resolution of the computer and display differently on the projector (or the second display). The desktop can be understood as two desktops of the computer, which is convenient for the computer to open any content or operation, and the person watching the projector (or the second display) will not see the operation on the computer.

1. First connect the projector to the WIN8 computer. After the preparation is completed, the projector will switch to the connected state. Press the shortcut key of WIN8 computer: WIN+P, mouse click “extension” function.

2. Click on "Extension"; Afterwards, the computer screen temporarily turns black, the resolution does not change, and the projector starts to display a blank win8 desktop.

The projector will not change anything in any operation on the computer, except that the taskbar will occasionally display the open icon. However, if you move the mouse up, down, left, and right, you will find that the mouse movement in the up, down, and left directions is bordered, that is, the edge of the screen cannot be moved. Moving to the right, you can see that the mouse has disappeared. Then look at the second screen, the mouse is already inside the screen displayed by the projector.

3, the mouse moves to the right to the desktop displayed by the projector, you can perform the corresponding operations, such as opening files, opening files that need to be played, etc.; of course, you can also in the computer screen, Drag the window to the right, you can directly drag to the desktop displayed by the projector. If it is PPT, click play, you can explain it.

4. If you need to find other information while projecting, just move the mouse to the left and move it to the computer screen. You can safely find your own computer folder. Anything on the projector can be seen. Not too much. You can also put a movie or PPT on the projector (or the second monitor), and work or play with your own peace of mind.

Note: The keyboard can be used on the desktop where the mouse is located, for example, when PPT is placed (↑↓←→).
