    First, because you set up the projector to jump to the projection mode directly, the adjustment method is the window key (the button next to Alt in the lower left corner) +P   adjust to copy will be two together shown.

    Second, when the computer is connected to the projection, there are 4 modes to choose from,  only computer mode, only the computer display, the projector does not display,  copy mode, The computer and the projector display the same content, easy to operate, extended mode, the projector or computer can be displayed as an extension of the desktop, only the projection mode, that is, the projector display, and the computer is a black screen.

    First, check if your computer graphics card is allowed to display dual or more screens by checking There are several sockets on the computer graphics card. The display signal lines we usually use are VGA, as well as DVI and HDMI. Generally, the double plug will be equipped with an HDMI jack, because the small size is not very space-consuming;

    Second, insert the data lines of the two display screens on the same graphics card, and then the display is powered. Right click on the desktop. In the pop-up dialog box, select [Screen Resolution].


    Open the screen resolution. When you change the display appearance page, you can see that there are two displays, labeled 1, 2 respectively. Only the 2nd display is gray at this time.

    If the two displays are not displayed, restart the computer without confirming that there is no problem with the display and data lines.

    4. Find the [Multi-Monitor] function in the setting position below, and change the original function [Show desktop only on 1] to [Expand these displays], of course you You can also choose to [copy these displays]. It doesn’t make much sense because your two displays show the same content.

    5. Click [Expand these displays] and click the [Apply] button below. At this time, the system will pop up a dialog box asking if you want to keep the settings, click [Keep Settings]. At this point you will find that the original gray monitor No. 2 is now also programmed with the same color as the one.

    Six, and the desktop drawing of the main screen will be displayed on the 2nd screen, but there is no navigation bar below. At this point, the extra software on the first screen or the browser can be pulled down on the No. 2 screen to realize the split screen display. Of course, how many screens are divided depends on how many interfaces your host’s graphics card supports. The expansion of the laptop is simpler, and the display data cable can be directly plugged in and displayed.

    Buy a VGA-HDMI converter. Use a conversion cable to connect. Generally, there is a VGA interface on the computer, which is a lot of trapezoidal eyes, usually blue.
