How to un-stretch the image of MW3 on ultrawide monitors.
 
 

The Problem & The Solution

All of this information is originally from wsgf’s page for MW2, it just also happens to work for MW3. ( https://www.wsgf.org/dr/call-duty-modern-warfare-2/en – [wsgf.org]  )
 
 
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:

 
1. Download HxD ( https://mh-nexus.de/en/hxd/ – [mh-nexus.de]  )
 
 
2. Navigate to the MW3 installation folder.
 
 
3. Open iw5sp.exe in HxD by simply dragging it in to HxD window.
 
(I recommend you make a backup of the original .exe before you make any changes)
 
 
4. You should see something like this, head over to search and click on Find.
 
 

 
 
5. Select “Hex-values” and search for 39 8E E3 3F as seen here:
 
 

 
 
6. You should be taken here with the values selected:
 
 

 
 
7. 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.
 
 

 
 
8. You’re done! You can now open the game like normal.
