To connect the projector to a computer, there are several considerations for these devices. Usually, users find it difficult to use the projector and monitor at the same time.
Necessary
DVI-VGA adapter
Instructions
Step 1
This problem can be solved by several methods. The choice of the method that is convenient for you should be based on the presence or absence of certain features of the projector. First, try connecting your projector and monitor to your computer's graphics card at the same time.
Step 2
The problem is that many projectors only have a VGA port for receiving video signals. If a monitor is already connected to the VGA output of the computer's video card, and this device does not have a DVI (HDMI) port, then purchase an additional adapter. There are special adapters that connect to the DVI output. Now connect your projector to this adapter.
Step 3
In a situation where you do not have the opportunity to purchase a suitable adapter or the second port of the video card simply does not work, use a projector to connect a monitor. A prerequisite in this case is that the projector has a VGA output.
Step 4
Connect the monitor to the projector using the regular VGA-VGA cable that you disconnected from the computer's video card. Connect the projector to the VGA port of the computer. The signal will now be sent to the monitor through the projector, allowing these devices to be used at the same time.
Step 5
If you used the first type of connection, then adjust the settings for synchronous operation of the projector and the monitor. Open display settings. Select the graphic image of the desired device and activate the item "Make this screen the main".
Step 6
Now select the type of simultaneous operation of your devices. In the case of a projector, they usually use the “Duplicate Screen” function. This will cause both devices to display the same image.
Step 7
If you need to hide the monitor from prying eyes, then select the "Expand screen" function. To display an application on the projector screen, move its window outside of your monitor.
