Q: In “Extended” mode, why does the cursor disappear?
A: If you’re in extended mode but have not yet connected the add-on monitor to the
U244-001-R, the desktop will still pan to the add-on monitor. It’s possible that
your cursor has moved to the extended desktop and is no longer visible on the
primary display.
When this occurs, try the following:
• Connect the add-on monitor to the U244-001-R. You should be able to see
the mouse cursor once the computer screen is displayed.
• Move your mouse to try and drag the cursor back onto the primary monitor.
• Unplug the U244-001-R from the computer to restore the cursor.
