== Notes and version constraints ==
* The line gpu_mem=512 applies to standard Raspberry Pi models; for the Pi Zero series it must be changed to gpu_mem=256.
* When using a Raspberry Pi 4, the dtverlay vc4-fkms-V3D must be enabled.
* If the screen stays black despite an HDMI signal: connect the HDMI cable first, then plug in the power supply (or re-plug the power).
* The AIDA64/Wallpaper Engine tutorial involves external downloads and paid software; these steps require human confirmation and local adjustments.
* Some motherboards require the HDMI cable to be connected before powering on – the sequence may be motherboard-dependent.
* Exact power consumption depends on brightness state; other operating states are not specified.
