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.
DPI Screens

Pros:

  • Often very high (nearing cell phone ppi) resolution
  • Amazing image quality
  • Can reach 60fps

Cons:

  • The most expensive option
  • Will use all or nearly all GPIO pins
  • Often designed as "Hats", making them large & thick.
