I set the monitor to be the main screen and laptop&#39;s LCD panel to be the secondary monitor. When I try to run my game full screen it shows the bottom right 1/4 of the game in the upper right 1/4 of the monitor. I have seen this same behavior on several comericial games, specificly in earlier versions of WoW; later version work correctly. <br /> <br /> I used to think that it was a problem with my system but three Vista laptops later it is still the same and commericial games are able to make it work.<br /> <br /> Has anyone else seen this type of behavior?<br /> <br /> Does anyone know how to fix it in an XNA game?<br /> <br />
