Common causes
- outdated GPU driver
- integrated graphics with no OpenGL support
- GPU doesn't support OpenGL 4.4+
- remote desktop or virtual machine
- Windows using Basic Display Adapter
How to fix it
- Update GPU driver
- ensure dedicated GPU is used
- install proper graphics driver instead of Basic Display Adapter

"Pixel format not accelerated" or "GLFW error: pixel format not accelerated" means Minecraft can't use OpenGL on your GPU. Either your GPU driver doesn't support OpenGL, or your system is using the wrong GPU.
How to fix it:
- Update your GPU driver — download the latest from NVIDIA, AMD, or Intel's website. Do NOT use Windows Update for GPU drivers
- Check if Windows is using the 'Basic Display Adapter' instead of your real GPU: open Device Manager > Display Adapters. If you see 'Microsoft Basic Display Adapter', your GPU driver isn't installed
- For laptops with dual GPUs, make sure Minecraft uses the dedicated GPU: Windows Settings > Display > Graphics > add javaw.exe and set to 'High performance'
- If using Intel integrated graphics, check that it supports OpenGL 4.4+ — very old Intel HD graphics (pre-2015) may not support modern Minecraft
- Disable 'Optimized' shader settings in Minecraft if you added OptiFine or Sodium
- Make sure you're not running Minecraft through Remote Desktop (RDP) — it doesn't support OpenGL
- Install Java with the correct architecture (64-bit Java for 64-bit Windows)
