Certain games such as Call of Duty: Modern Warfare 2 may not scale the screen correctly when a super wide resolution is used. To correct this problem, you will need to download and use the 3rd party utility Widescreen Fixer:
Widescreen Fixer is compatible with Punkbuster and will not be detected as a cheat or unauthorized hack.
Widescreen Fix will only correct your in-game display. The game menu will still appear stretched.
When visiting the download page for Widescreen Fixer, please select version 2.00 or higher.
