Screens

3.5" Screens for GBZ

Composite/TV Screens

Pros: Cheap Simple to install Usually only need 1 wire (plus power & ground). Cons: Low Resolution Analog nature makes them sensitive to interference and ghosting. Many different variations makes standardizing difficult.

SPI Screens

Pros: Often better resolution than Composite/TV screens Digital nature makes perfect picture clarity Typically needs 7-10 wires, more than Composite, but less than DPI. Cons: Often designed as "Hats" that sit on the pi taking up a lot of space and all the GPIO pins even if not needed. Can vary wildly on driver support. Even some well known sellers can unofficially EOL these by not updating drivers and install guides SPI has very low bandwidth, leading to stuttering and FPS issues. Are often 16:9 ratio rather than 4:3 like the Composite screens: Fitting into a GBZ may be difficult or impossible.
