My good lady likes to play Hidden Object Games and the like and some of them do not open full screen but windowed on her LG Flatron IPS235v-bn Resolution 1920 x 1080. I on the other hand as a secondary monitor have a Dell U2410F same resolution and all the games or at least the ones I have tried automatically open full screen. There are no setting that are not exactly the same on both PC's but one shows the games windowed and the other does not. What am I missing?
