It sounds like your problem is that you have created a layout using the native resolution of the laptop, and not extended displays, and then you connect the VGA cable and move the display and the tournament screen is now showing at a different size from once you designed. Your best way to workaround this is have your exyended display hooked up or another display and edit down the display until it's correct at 1024x768, including rescaling images etc.
You can hook up HDMI which will work (most of the time) at higher resolutions and/or can match the resolution you created the screen at, but to be honest, your better sticking with VGA, and re-sizing the layout instead as HDMI is not the best for extended displays, apart from the resolution problems VGA really is a far better & easier medium to work with IMHO.
