Assuming he has a dual display video card, it sounds like he is set up in CLONE mode and not EXTENDED DESKTOP mode like it should be.

1-The second monitor/tv must be connected to the p.c and turned on when this change is made.

2-Right click anywhere on a blank spot on the pc desktop.

3-click on PROPERTIES.

4-Click on SETTINGS.

Two monitors should be showing, #1 the pc monitor(highlighted), and #2 monitor.

5-click on the #2 monitor

6-check the block on the page that says "Extend Mt Windows Desktop To This Monitor"

7-Click Apply.

Hope this helps him.
