GG CleanScreen 2.0 | Install Guide
Hold Start + 2 + Left to get into the menu. Left and 2 move the menu left and right, and Start goes in and out of menu.
This guide is for the new V2 version of the Cleanscreen PCB and flex cables. The V1 boards are identical in install, except you no longer a need to solder HSYNC or VSYNC, and instead you also need to send DAT4 to ground if using our IPS (latest) LCD, or 5V if using a TFT LCD.
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).
