NVIDIA Corporation 79Chapter 6Configuring HDTVOverscan ShiftThe Overscan shift setting enables you to pan the desktop, when needed, to accessany display elements that appear off‐screen.The Overscan shift feature works by tracking the position of the mouse cursor andslightly shifting the display when the cursor starts to become close to an edge of thedesktop. This mode looks just like “native” HDTV formats (720p, 1080i) because itruns at the full HDTV resolution, which causes certain elements of the desktop, suchas the Start button and the clock on the Windows taskbar, to not be visible at alltimes. But as the mouse cursor gets close to these desktop elements, the NVIDIAdriver intelligently shifts the desktop a little in order to move those elements intoview.“Using Overscan Shift” on page 86 explains how to use the Overscan shift setting.NativeIn the third technique, native mode, no overscan compensation is done in order togive the user a true cinematic experience. This is useful when you do not want anypixel compression (squishing) and do not want to use the mouse to shift the desktopimage.Notes on Startup Functionality with HDTV ConnectednView Single Display ModeWhen you first start your computer, the HDTV display may have color distortionand may not fill the entire screen display.
