RGB Mod via Direct Injection

Some monitors can have RGB input directly injected to the chroma chip. Sometimes the chroma chip has unused RGB inputs for the OSD menu and sometimes it even has dual RGB inputs, one set for OSD and one for an unused SCART input. In rare cases external hardware such as Arduinos or custom PCBs are necessary to handle RGB injection but in most cases you can connect directly to these unused pins on the jungle.

Specific instructions for direct injection of RGB signals can be found on the specific CRT's page.
