4. Select your projector's Display Name from the list.
5. If you see the PIN entry screen on your computer, enter the PIN code displayed on the Screen
Mirroring standby screen or at the bottom right of the projected image.
The projector displays the image from your computer or mobile device.
Note: It may take some time to establish the connection. Do not disconnect the projector's power
cord while it is connecting to your device. This may cause your device to freeze or malfunction.

Secure HTTP
You can use the HTTPS protocol to increase security between the projector and a web browser
communicating with it (PowerLite 1781W/1785W/1795F). To do this, you create a server certificate,
install it on the projector, and turn on the Secure HTTP setting in the projector menus to verify the
reliability of the web browser.
Even if you do not install a server certificate, the projector automatically creates a self-signed certificate
and allows communication. However, because the self-signed certificate cannot verify reliability from a
web browser, you see a warning about the server's reliability when you access the projector from a web
browser. This warning does not prevent communication.

Importing a Web Server Certificate Using the Projector Menus
You can create your web server certificate and import it using the projector menus and a USB flash
drive.
Note: You can also register digital certificates from your web browser. Make sure to only register once,
or the certificate may not install correctly.
1. Make sure your digital certificate file is compatible with projector registration and saved in the root
directory of the USB flash drive.
2. Press the Menu button on the projector or remote control.
