The BitLocker Drive Encryption Password Entry screen may appear with reduced clarity on Windows 8-based computers

Symptoms

When you boot a Windows 8 device that is encrypted using BitLocker, the BitLocker PIN or Recovery Password Entry screen, fonts and text may appear with reduced clarity (blurry).

Cause

This issue can occur if you are running an incompatible BIOS/Firmware.

Resolution

Contact the hardware manufacture to check for a BIOS/Firmware update that is tested and supported for Windows 8.

More Information

To properly support booting Windows 8 in UEFI mode with BitLocker enabled, ensure that the system is on UEFI firmware version 2.3.1 and that the UEFI firmware is in native mode without a Compatibility Support Module (CSM) for BIOS mode enabled.
