Yesterday, I shared a great tool to adjust the field of view (FOV) for the aspect ratio of your monitor, according to the game you are playing.
Like I mentioned in that post, Call of Duty: Modern Warfare 2 is one of those games that doesn’t work well with widescreen monitors. Over at Widescreen Gaming Forums, a fix has been posted that you could try.
This is a very common issue with gamers having widescreen monitors to play games. Of course it’s more fun to play on widescreen monitors than the usual ones, but the game developers should also understand this.
For example, Call of Duty: Modern Warfare 2, the game that broke records of the entire entertainment history in terms of sales, doesn’t support high widescreen resolutions.
