i think thats all to do with air flow, basically if you put a massive screen in front of your face the air will flow over the top of the screen but will then create a suction effect after it and this is what most people feel and complain about when they have massive screens. This is the reason why so many screens have holes or gaps at the bottom to allow a bit of air flow in to distort this suction meaning you get a better, nicer ride. This is what you did with your spacers but with out knowing it.
