Issue: Application fails to enter exclusive full-screen mode; displays as windowed, black screen, or incorrect scaling.

Even if the option is broken, the universal Windows shortcut (Alt + Enter) forces most DirectX/OpenGL applications to toggle full screen. If this works, the issue is likely a missing UI button binding, not a rendering engine flaw. pixel game maker mv not working full

PGMMV was built for older display standards. If you’re on Windows 10/11 with a high-res monitor (1440p, 4K) or display scaling set above 100%, the engine gets confused. Document ID: PGMMV-DISP-2024 Product: Pixel Game Maker MV

The Fix (for the Editor & Game Preview): Right-click PGMMV

Right-click PGMMV.exe (or the launcher).

Select Properties > Compatibility.

Click “Change high DPI settings”.

Check “Override high DPI scaling behavior”.

In the dropdown, select “Application” (not System).

Click OK → Apply.

Now relaunch PGMMV. Does the preview window fill the screen properly? For most people, yes.

Discord, NVIDIA GeForce Experience, or Steam overlays can intercept Alt+Enter commands, preventing PGMMV from receiving the full-screen toggle signal.
