Configuring HDTV
Overscan Shift
The
Overscan shift
setting enables you to pan the desktop, when needed, to access
any display elements that appear off-screen.
The Overscan shift feature works by tracking the position of the mouse cursor and
slightly shifting the display when the cursor starts to become close to an edge of the
desktop. This mode looks just like “native” HDTV formats (720p, 1080i) because it
runs at the full HDTV resolution, which causes certain elements of the desktop, such
as the Start button and the clock on the Windows taskbar, to not be visible at all
times. But as the mouse cursor gets close to these desktop elements, the NVIDIA
driver intelligently shifts the desktop a little in order to move those elements into
view.
“Using Overscan Shift” on page 88
explains how to use the Overscan shift
setting.
Native
In the third technique, native mode, no overscan compensation is done in order to
give the user a true cinematic experience. This is useful when you do not want any
pixel compression (squishing) and do not want to use the mouse to shift the desktop
image.
Notes on Startup Functionality with HDTV Connected
nView Single Display Mode
When you first start your computer, the HDTV display may have color distortion
and may not fill the entire screen display. This is because when you first start your
computer with a newly-installed driver, the TV signal format defaults to NTSC.
nView Multi-Display Mode
When two displays are connected to your computer, you will notice both displays are
mirrored or “cloned” — this is nView Clone mode.
