Most CDi’s require a modification to output RGB and some are much easier than others. Please see below for details.
|CDi-220 RGB Mod
This guide shows you how to mod your CDi-220 for RGB-output.
There’s a fix in the works for a top-loading CDi RGB mod!
Thanks to confirmation from Europe, I now have information that some PAL CDi’s actually have an RGB SCART connector on the back. This has been confirmed to output RGB and not just composite-via-SCART:
To summarize, here’s what I suggest for the CDi:
– If you own a CDi-220 and want RGB, follow my guide for easy RGB!
– If your CDi isn’t a 220 model, I suggest opening it up. If you see the Sony CXA chip that’s pictured in the guide, try wiring yours the same way and cross your fingers!!!
– If you have a CDi 450 (top-loader) try the mod listed here: http://8bitplus.co.uk/your-consoles/philips-cdi-450-rgb-mod/
