If you are using the DVI output from your video card and the DVI input to a TFT monitor, no adjustment should be required. In other cases, when the
video signal is converted between analog and digital formats, either by the Local unit and/or the monitor, you may need to optimize the video signal using
the Extender’s on-screen display (OSD).
