Connect your DisplayLink device to one of the USB ports. Start the qtdloprez executable and select the Load PDF... in the Presentation menu. Select the resolution you'd like to display the presentation in, then select the PDF file. Please wait while ImageMagick converts your PDF into PNGs of suitable size. When it's ready, the first page will be shown both in the window and on the external display. You can step forward and back by pressing the Spacebar and Backspace or using the Presentation menu.
