no mention of DPI capabilites

Jump to: navigation, search

The BCM2835 GPU is capable of driving DPI video, up to 6 bits on 3 channels, directly from the GPU. Hardware such as https://www.adafruit.com/product/2454 exploit this (sacrificing most of the GPIOs). This requires configuration of the GPU as well as an overlay for Linux.

Anyhow, I believe this capability deserves mention.
