Hyperpixel 4 Non-touch and Pi-Zero W

Followed instructions per Getting Started with HyperPixel 4.0.

Installation completed and after reboot the screen displays the boot process then goes blank.

What Raspberry Pi OS version are you using? If it’s Bullseye, it’s not working with Hyperpixel yet - best to use Buster for now (accessible in Raspberry Pi Imager under Raspberry Pi OS > Other and Raspberry Pi OS (Legacy))
