Before using the Booster for HDMI with EDID Detective, the unit must be programmed with 

an EDID.  Once programmed, the EDID data will be read by the source, providing all the 

necessary details of the type of signal that the display (or other sink device) can process. 

 

There are two ways in which to program the booster:  1) The EDID data can come from 

an external source, such as a display or A/V receiver.  2) The booster can be programmed 

using any of the 6 Default EDID profiles .

1.  Begin by powering-on the display or other sink device containing the EDID to be 

recorded. 

2.  Connect an HDMI cable from the sink device to the 

HDMI Out port on the booster. 

3.  Set all DIP switches to the OFF (up) position, as shown below. 

 

 

 

 

 

 

 

 

 

 

4.  Set the 

WR (write) switch to the E position in order to allow the EDID to be written to 

the booster. 

5.  Connect the included 5V DC power supply to the booster.  The 

Power LED will glow 

bright green. 

6.  Press and hold the 

Program button on the booster, until the Power LED begins to 

flash rapidly.  The Power LED will continue to flash as the EDID is recorded by the 

booster.  This process only takes about 1 second.
