The Problem & The Solution

Note: Credit goes to Recon

All of this information is originally from wsgf’s page for MW2, it just also happens to work for MW3.

The game is stretched on 21:9 monitors out of the box, which is less than ideal. Not to sweat though, the fix is easy enough to apply.

Here’s How to Fix It

  • Download HxD
  • Navigate to the MW3 installation folder.
  • Open iw5sp.exe in HxD by simply dragging it in to HxD window.

(I recommend you make a backup of your original .exe before you make any changes)

  • You should see something like this, head over to search and click it.
  • Select “Hex-values” and search for 39 8E E3 3F as seen here:
  • You should be taken here with the values selected:
  • Replace the values with CD 90 18 40 like seen here. (You can simply copy paste them.) After you’ve changed the values, save the file.
  • You’re done! You can now open the game like normal.

The Results

How did it help? See for yourself:

Some UI elements, like the menus may still appear stretched even after applying the fix.
