Hi, While calibrating my projector I came over a setting called overscan which I don't understand. I'm using a BR disc to set sharpness, one of the screens there let you calibrate the image to fit exactly in your screen. In the cornes you have arrows indicating the image format 16:9, 4:3, etc... To fit the 16:9 size in my screen I need to set the overscan to the max, otherwise it's not visible. In the manual of the projector you can only read that pushing the overscan to the max could affect the sharpness of the borders. Did I position my projector wrongly that it doesn't show the full 16:9 screen, or what is overscan all about?
