HD4K-EDID-EMLTR
HDMI 2.0 EDID Emulator
The HD4K-EDID-EMLTR HDMI 2.0 EDID Emulator copies the EDID of the desired HDMI display and connects directly to the HDMI
source to ensure that the EDID is not lost in connections between devices such as switches, splitters, and extenders.
Emulates an HDMI display (sink device) by providing Hot Plug Detect and EDID to the HDMI source device.
Supports Ultra-HD 4Kx2K resolutions up to 3840x2160 @60Hz 4:4:4, 2560x1440p (WQHD), HDTV resolutions to 1080 p, and
up to 1920x1200 (WUXGA).
HDMI features supported:
o HDMI 2.0
o 12-bit Color / 36-bit Deep Color
o RGB, YCC 4:4:4, YCC 4:2:2
o LPCM 2-Channel
o Bandwidth up to 600 Mhz (18Gbps)
o Support for CEC (consumer electronic control) compatible devices.
o 3D
o HDR
HDCP 2.2 compliant.
Supports Learning and Emulation modes.
o Learning mode: store a display's EDID for later use.
o Emulation mode: provides EDID to the HDMI source device from the emulator's internal memory.
Supports headless operation – no monitor attached to source.
Pre-programmed with many standard resolutions with native set to 1080p.
o Use learning mode to program other resolutions.
LED indicators provide signal status information.
Compact design for easy installation and operation.
No power supply - powered by video source.
Ideal for resolving signal handshaking problems between a source and a display.
Installation
1. Connect an HDMI cable between the emulator (at "Display") and the HDMI display device.
2. Plug the HDMI male ("Source") connector of the HD4K-EDID-EMLTR emulator into the HDMI video source.
3. Unplug the HDMI cable from the emulator, causing the blue LED to flash. This indicates the emulator is in Learning Mode.
4. Within 10 seconds, plug the HDMI cable back into the emulator. The Green and Blue LEDs should change to solid ON, indicating
that Learning Mode has been successful and the emulator is now in Emulation Mode.
Note: If the HDMI emulator needs to be reset back to its default EDID resolution of 1080p:
1. Start from Step 1 (above) and after step 2 simply unplug the HDMI cable from the emulator. The emulator will return to
Learning Mode.
2. Allow 10 seconds to elapse, at which time the blue and green LEDs will turn OFF and Learning Mode will fail. The
emulator will now be set to 1080p.
3. If you now unplug the emulator from the video source, and then reconnect it to the video source, the green LED will turn
ON indicating it is set to default 1080p.
To prevent the HD4K-EDID-EMLTR from going into Learning Mode, unplug the emulator from the video source before disconnecting
it from the display device.
Connect to Your Application
Once the emulator has learned the EDID table and is in Emulation Mode, the emulator can be placed in its ultimate configuration,
following these steps, in order.
1. Unplug the emulator from the video source.
2. Unplug the cable from the "Display" port going to the monitor.
3. Make your connections from the HDMI cable to the display, splitter or extender and power the splitter or extender and associated
display(s) ON.
4. Plug the HDMI cable back into the "Display" port on the emulator.
5. Plug the emulator back into the video source.
The EDID table copied during the Learning Mode will be available to provide the desired resolution to your monitor(s). Note: Make
sure your monitor is capable of displaying the selected resolution.
Note: The HD4K-EDID-EMLTR is not recommended for use with KVM or Video-only switches. Using it with a KVM or Video-
only switch will cause the emulator to go into learning mode and/or cause your display organization of applications and files
to be re-arranged each time the video input on the switch is moved to another input and then back again.
