It seems that someone have successfully installed the driver for Windows 11 arm, and it can let the screen resolution to be 1920x1080@60Hz.
But I cannot find this driver, it is not available on ASPEED's download page (Only x64 driver there).
So has anybody tried to get the intergrated vga card to work properly?
