Ultrawide & Half-Screen Display Issues (Odyssey G9 / 49” Monitors)

If you’re using an ultrawide or super ultrawide monitor (like the Samsung Odyssey G9 or similar 49″ screens) and only seeing part of the game or the cheat overlay—for example, ¾ of your desktop and ¼ of the game—this guide explains how to fix it.

The Issue:

When using Fullscreen Borderless, Battlefield 6 and other games may only show part of the screen or appear zoomed/cropped.

This happens because these monitors use two physical panels (5120 width) detected as one combined display, which can confuse overlays and fake screen rendering during injection.

The Fix (Quick Steps):

1. Open Windows Display Settings
   
   
   • Right-click the desktop → Display settings > Change Your Resolution Temporarily
     
     
   • If your monitor resolution is 5120×1440, set it to 2560×1440 before injecting.
     
     
   • This halves the screen width and removes black bars issues. Launch the Game and Inject
     
     
   • Start Battlefield 6.
     
     
   • Once the game is fully running and injected, everything should display correctly. Optional: Restore Full Resolution After Playing
     
     
   • When done gaming, switch back to 5120×1440 for normal desktop use.
     
     

Why It Happens:

• Ultrawide monitors like the Odyssey G9 use two 2560×1440 panels internally.
  
  
• The cheat overlay hooks to one of those EDIDs (panel IDs) instead of the combined view, causing it to appear in only part of the screen.
  
  
• Using 2560×1440 ensures both the game and overlay align correctly within a single panel.
  
  

Additional Tips:

• Ensure your Display Mode is set to Borderless Windowed, not Fullscreen.
  
  
• Avoid custom scaling or display zoom under Windows settings.
  
  
• Disable monitor software that “splits” screens (e.g., Samsung Easy Setting Box, PowerToys, Etc) for stable injection visuals.
