This guide is for the older purple boards, but the new purple boards are identical in install, except no longer a need to solder HSYNC or VSYNC, and instead you also need to send DAT4 to ground if using our IPS (latest) screen, or 5V if using a TFT. Finally, send DAT5 to ground by default, and if you get color issues that toggling the 1CHIP/2CHIP switch doesn't fix, send DAT5 to 5V instead (follow this guide ).
