The GPD Duo updates in two parts: chipset and GPU drivers come from Windows Update and the GPD download page, while the BIOS and EC firmware are flashed from a FAT32 USB drive via the FN + F7 boot menu. Because the Duo has two OLED screens, keeping graphics drivers current matters for display behavior. Confirm your CPU in Task Manager first and keep the device on AC power the whole time.

FAQ

Do dual-screen issues need a firmware update?
Often yes for display behavior; update the BIOS and install the latest GPU/chipset drivers from gpd.hk and Windows Update.
F7 is not opening a menu.
Hold FN and tap F7 repeatedly right as the device powers on; the USB drive must be FAT32, not NTFS.
