How to make WMV automatically open in full screen

I have a .WMV of a powerpoint presentation. I have created a shortcut in the startup so that it opens up each time Windows starts, but seems I can only get it to open in maximized view, but I need it in full screen. The reason being is this is going to be displayed on a 40" LCD TV screen and needs to optimized to its full display.

I've put in "/fullscreen" into my target path. The video auto opens up, but still showing as maximized view. When I hover over, the full screen option is still available.

Is there a fix for this?
