Computer connected to two monitors

Asked by: Kathleen Ward 229 views Computer August 20, 2018

Have you ever encountered a connection between two monitors, of which the monitor No. 2 only has a windows start signal when it is turned on, and there is no signal on the monitor No. 2 after the host is started. The control panel displays the dotted line in the setting, and the switch is turned on and off.

Addition: Point recognition only 1 display will show, 2 does not light

    Multi-screen display requires multiple display interfaces to implement. See if one of the display interfaces is not connected, or a wire problem.

    It is very likely that your device does not support multiple displays

    In general, we won’t do this, but it’s not impossible to do this.

    This depends on whether the graphics card supports multi-screen display function, if you have VGA or HD, you can set the multi-display to be OK.

    After connecting the two graphics card output jacks, first test whether the two monitors are switched properly in the control panel, then open the software and let the two monitors be on different desktops. .

    The problem you said seems to be that the sub-monitor computer does not recognize it. Try installing the sub-display driver.

    It doesn’t matter when you turn it on. The main and sub-display settings are expanded

    1. 2 interfaces of the computer’s graphics card Connect one monitor to each, and connect the two monitor power switches when connected.

    2. After connecting, the computer will boot into the system, then right click on the desktop, enter the screen resolution interface, select “Extend these displays” in the multi-screen display drop-down menu and click OK.
