These emulators are designed for systems that require EDID/DDC signals to be continuously provided without interruption. Some computer systems, KVM switches & digital video signage systems may interrupt the data, or may not be able to pass this information directly back to the video card's display port. This simple solution will provide preset/default EDID/DDC information, or when used with the LINDY EDID/DDC Emulator can provide cloned EDID/DDC information to your graphics card.
