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

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 FancyZones) for stable injection visuals.
