How to set ' Transformers: Revenge Of The Fallen ' by a resolution of 1440x900 pixels ? I have a screen with this resolution but i cant set the screen to it .The highest resolution shown in the game is 1280x1024 pixels .Please help quick it would be a great help for me .|||If higher resolution can not be set, perhaps the game is detecting that your graphics card will slowdown at higher than 1280x1024. Your graphics card might just be meeting MINIMUM requirement.
