This is called overscan mode and is a common mode for DLP televisions set by the HDTV manufacturer. Some televisions have a built in mode called "Reduce" which allows you to view the entire Windows desktop, but this mode is not compatible with stereoscopic 3D gaming.

The options on this Resize HDTV Desktop page appear if you have set the NVIDIA Control Panel View menu to Standard.
You can resize the desktop appearing on your HDTV screen if your desktop is extending beyond the viewable display area or the desktop or image is not filling the entire display area.
1.From the NVIDIA Control Panel navigation tree pane, under Video & Television, click Resize HDTV desktop to open the associated page.
2.Click the Resize Desktop button.
Use the slider to increase or decrease the size of your desktop/picture until you get the desired result.
