Fixing the System

If you cannot install Wireless Presenter-to-Go on your handheld organizer:

If the installation fails to install the software on your computer, be sure your computer meets the minimum requirements. See “To prepare your handheld organizer for wireless presentations” on page 29.

Be sure your handheld organizer meets the minimum requirements for Wireless Presenter-to-Go. See “To prepare your handheld organizer for wireless presentations” on page 29.

If an earlier version of HP Wireless Presenter-to-Go is installed on your device, try uninstalling it before installing a new version.

Presentation problems

If the projector does not show your computer display over a network or wireless connection:

In Wireless Presenter-to-Go, be sure you have connected to the desired projector.

If the Wireless Presenter-to-Go window has a Start presentation button, click it. Your computer might be connected but not presenting.

Make sure you have selected the connectivity module as the active input on the projector. Open the on-screen menu and select Input > Connectivity module.

Be sure your computer display is set to XGA resolution

(1024 × 768). Check this in Control Panel Display on the Settings tab. An alternative is to use the extended desktop option in Wireless Presenter-to-Go—see the next bullet.
