Solve your HDMI EDID display problems
The HDMI EDID Feeder
The ideal addition to your toolkit. Fix display problems by installing this device in line with your source and setting your own EDID. Ideal for when the display does not have the correct identification or where the EDID is lost when using splitters or extenders.
16 settings available from 720p to 4k with various audio options.
What is EDID?
EDID (Extended Display Identification Data) is the name for the data held within a display which contains details such as maximum resolution, aspect ratio, colour capability and audio capabilities. When a source is connected to a display via an HDMI cable (e.g. a Blu-ray player is connected to a TV) the TV relays that information back to the Blu-ray player so that the Blu-ray player can produce the most appropriate image for that display. That usually means that the Blu-ray player produces a 1080p image for a 1080p capable TV, a 3D image for a 3D capable display, or a 720p image for a 720p capable display. In other words, it attempts to produce the highest quality image that the display can cope with.
Why might you need this HDMI EDID Feeder?
When only one source is connected to one display, the communication between Blu-ray and TV goes to plan as in the above scenario. But what happens if more than one TV is connected to the same Blu-ray player via an HDMI splitter as in the Typical HDMI Network diagram below?
The Blu-ray player in the above scenario cannot now send out the best image to both TVs, so there has to be a compromise.
Depending upon the design of the splitter and how it is connected, it may take the EDID information from the 3D TV and send out a 3D image to the TV at the top of the diagram, and that TV would work fine. But the splitter is only capable of duplicating the one HDMI signal that it receives, so it will also send out a 3D image to the non-3D capable TV and this will not make good viewing (the lower TV will not be able to produce a watchable image).
A slightly different scenario is where an extender over Cat5/6 cable is used to extend the distance between the Blu-ray player and a single TV. In this case, the EDID may be lost completely so the Blu-ray player would revert to a default setting that may not be a good match for the TV being used.
The Blu-ray player must be told how to deal with these situations.
By placing the HDMI EDID Feeder in the position shown on the diagram on the right, an EDID setting can be selected which will allow both TVs to display an image. The Blu-ray player will read the data according to the position of the 16 position switch, rather than from either of the TVs connected. The best option should be selected based upon the capabilities of the least capable TV. In our example, setting D should be fine allowing both TVs to display non-3D 1080p video with 2 channel stereo (the settings are listed on the base of the HDMI EDID Feeder for easy reference).
This is only one example. The difference between the displays might be 3D capability as above, it might be 4k capability, 1080p capability or it might be audio capability. The source may be satellite receiver or a DVD player and the network might include a multi-channel receiver/amplifier instead of a TV. However in all cases the principle is the same – the source must be presented with the most appropriate data and the HDMI EDID Feeder can provide the solution.
