HDCP
Determining a video display’s HDCP compliance can be important when using content protected
media sources. If a display is not HDCP compliant, the source will not transmit a video signal.
Note: Blu-ray content will not pass to a non compliant display.
A table has been included to make it easier to interpret the result of the HDCP test.

5V & Hot plug
When an HDMI connection is made between source and HDTV, a 5v signal is transmitted to the
display. This triggers a hot plug event from the display indicating that EDID is available for the
source to read. If this process fails, no video will be transmitted to the display.
The UHD-SYNC detects signals from the source and display, the corresponding LEDs will illuminate
green if the signal is good. Refer to the table below to better interpret the results and the steps
required to resolve the HDMI signal.

EDID (Extended Display Identification Data)
To ensure the best audio and video, the UHD-SYNC has 9 internal EDIDs and the ability to learn a
video display’s EDID.
Internal Mode
The 9 EDIDs below represent the most common audio format and video resolution combinations,
ensuring compatibility.
Mode 1: 1080p - 2Ch audio *3D and multichannel audio will not work in this mode.*
Mode 2: 1080p - Multichannel audio (HD lossless) *3D will not work in this mode.*
Mode 3: 1080p - 2Ch audio - 3D *Multichannel audio will not pass in this mode.*
Mode 4: 1080p - Multichannel audio (HD lossless) - 3D *4K will not pass in this mode*
Mode 5: 1080p - Dolby Digital 5.1 audio - 3D *Only Dolby Digital and 2Ch audio will pass in this mode.*
Mode 6: 720p - 2Ch audio *Multichannel audio will not pass in this mode.*
Mode 7: 1080p DVI *Recommended for use with DVI projectors*
Mode 8: 4K - 2Ch audio *Multichannel audio will not pass in this mode.*
Mode 9: 4K - Multichannel audio (HD lossless) *The highest resolution and audio will pass in this mode.*
Learning Mode
Mode 0 places the UHD-SYNC into learning mode. In mode 0 it’s only a few easy steps to learn
a display’s EDID - Used when a display’s EDID can’t be received due to faulty cables, component
cascading limits, or 9 internal EDID files aren’t appropriate.
To learn a display’s EDID:
1. Connect an HDMI cable from the UHD-SYNC’s HDMI output to the HDMI input on the display.
2. Plug the UHD-SYNC into the A/C wall outlet or local USB using the included mini USB to USB
cable
3. Turn the display on
4. Set the rotary dial to 0 (if on a different setting)
5. Press and hold the learn button
- The learn LED will blink green during this process
- If the EDID learn process is successful, the LED will turn solid
Signal Regneration
The UHD-SYNC performs signal regeneration to resolve clock stretching issues with unsupported
HDMI 1.2 devices. (ex. Cable set-top boxes) See page 8 for connection diagram.
