Correcting problems connecting the projector

If the video projector is connected and “no signal” is visible on the screen, you need to check a few points:

• Correct settings. When connected to a computer unit when the screen is the only monitor, the set screen resolution may become a problem. You will need to preset the values ​​that the projector supports. You can find them in the instructions or on the packaging.

Important! When the device does not see the connection to the projector, a system reboot can help. It is possible that automatic recognition of a new device did not work.

In the event that the laptop does not recognize the video projector and the signal does not appear, proceed as follows:

1. Go to the Control Panel in “Screen Settings” or right-click on the desktop and select the “Screen Resolution” section.
2. We select the necessary parameters, using the “Find” item, we search for the second monitor.
3. In the “Screen” item of the Control Panel, select “Connect to Monitor”.
