Summary
Launched in 1988, Commodore intended the 1084 to be a universal monitor compatible with all of their computers of the era. In addition to RGB and Composite it accepts S-Video, however the 4-pin DIN connector had not been standardized yet so instead it has two separate RCA inputs for S-Video - one for Luma and one for Chroma. To use this input you can either wire your own adapter or buy one online for cheap. It's referred to as an "S-Video breakout adapter".
The RGB inputs use a commodore standard 8-pin DIN which requires an adapter. If you are up for a DIY project you can also add your own SCART port to the unused port on the back of the monitor for easier RGB plug-and-play (see videos below).

Common Repairs
- Capacitor replacement: Recommend replacing any "taicon" brand capacitors in these monitors as they have a high failure rate.
