DR HDMI 4K will solve most HDCP/HDMI issues by just being connected between source and display. Once connected it can be set on the fly to perform specific EDID and Hot plug event.
There are a total of forty EDID banks (40) inside the unit. When you press up or down on the rotary button you can quickly move between any of them to select the desired one. Once you stop for a second or so, the system actually activates the selected EDID and starts the HPD (hot-plug) event. This is the event where Dr.HDMI 4K will inform the source device that EDID has changed so the source must reconfigure it’s own internal settings. This takes about 2 seconds as per standards. During this time you will not be able to change the EDID. After HPD event concludes you are free to change edid again if wanted.
If you press the copy sink button, the display’s EDID is copied and placed into the EDID bank number 8. Once it is done, HPD event is also created and completes in about 2 seconds.
