If you are having problems getting an HDMI source to display on an HDMI monitor or getting an AV receiver to recognise an HDMI input, this device may solve the problem. Rather than allowing the source to interrogate the display and come up with the appropriate resolution, this device sets the source to a specific resolution which is then passed on to the display or other AV equipment. 

This device is an EDID emulator which can solve HDMI resolution problems between source and display. EDID information is normally provided by a display to tell a source device what capabilities the display has in terms of resolution, image size, colour capabilities and sound channels. In some installations this information can be lost such as when certain HDMI extenders or a HDMI splitters are used, or when Chromecast or similar devices are connected to an AV receiver. Sometimes the display does not communicate the correct information and this can cause the source device to revert to a default mode which perhaps does not match the correct characteristics of the display, resulting in a lower resolution than the display is capable of.

This EDID feeder can resolve those problems as it is can emulate a display device and feed one of 16 different modes back to the source device. The source device will then produce the HDMI signal with the characteristics chosen according to the mode selected. The 16 modes available are as follows:

  • 4k 2 channel audio
  • 4k 5.1 channel audio
  • 4k HD
  • 1080p 2 channel audio
  • 1080p 5.1 channel audio
  • 1080p HD
  • 1080p 3D 2 channel audio
  • 1080p 3D 5.1 channel audio
  • 1080p 3D  HD
  • 1080i 2 channel audio
  • 1080i 5.1 channel audio
  • 1080i HD
  • 720p 2 channel audio
  • 720p 5.1 channel audio
  • 720p HD
  • Sink EDID (copy the output EDID)

The maximum cable length for both HDMI input and output cables is 5m.
