Front Counter - screen resolution
You may need to change the screen's display resolution to get the full POS form to display. Use Control Panel -> Display and change the resolution until it fits. If you still can't get it to fit then the video card you have does not allow the required resolution. If using a 15 inch screen the resolution needs to be 1280 by 1024. If your monitor does not allow that you may need to get another, higher resolution, video card.
