How to Use Exclusive Fullscreen for Zero Input Lag (26.1)

One of the most overlooked features in the 26.1 "Tiny Takeover" update is the addition of a native Exclusive Fullscreen option. For years, Minecraft Java Edition used "Borderless Window" by default, which can cause subtle input lag and sometimes conflict with G-Sync/FreeSync settings.

In 2026, competitive players on version 26.1 and above should always enable this for the smoothest possible experience.

1. Borderless vs. Exclusive Fullscreen

  • Borderless (Old Default): Easier to switch between apps (Alt-Tab), but your operating system is still managing the window, which adds a tiny amount of latency.
  • Exclusive Fullscreen (New): The game takes direct control of your monitor. This results in the lowest possible input lag and allows for better FPS stability.

2. How to Enable it in 26.1

  1. Open the game and go to Options.
  2. Click on Video Settings.
  3. Look for the Display Mode toggle (typically on the right side).
  4. Change it from "Borderless" to "Exclusive Fullscreen".
  5. Click Apply. Your screen will flicker for a second—this is normal.

3. Optimizing Your GPU Settings

Once Exclusive Fullscreen is enabled, make sure your graphics card software is correctly configured.

  • NVIDIA Users: Open NVIDIA Control Panel > Manage 3D Settings > Program Settings > Minecraft. Set "V-Sync" to "Off" and "Low Latency Mode" to "Ultra".
  • AMD Users: Enable "Radeon Anti-Lag" and "FreeSync" for the best results.

4. Troubleshooting

If your game crashes when you Alt-Tab after enabling this:

  • Solution: Java 25 has improved window management, but update your graphics drivers.
  • Alternative: If you need to Alt-Tab frequently, you may want to stick to Borderless.
TIP

Performance Tip: When using Exclusive Fullscreen, you should always combine it with Sodium and Iris for the absolute best performance in 2026. Check our Top Performance Mods Guide for more info.
