1-4 Main Features

1. High Quality Picture - No Signal Loss and Digital Noise Free Our Distribution Amplifiers are built to deliver the highest quality picture preserving the native resolutions of the video sources without any signal loss. At the same time, the digital noises that may affect the picture quality will be eliminated. Due to the nature of the digital signals and passing through multiple stages of connection when using distribution amplifiers, it is important to eliminate the digital noises and boost the signal strength to preserve/enhance the video signal quality.
2. Signal Amplification for signal reliability and long length signal transmission Our 5V power adapter supplies adequate power to amplify the video signals from the video source. This is necessary as the overall length from the video source to the displays is longer when using the distribution amplifiers (distance from the video source to the distribution amplifier + distance from the distribution amplifier to the display). In most cases, the overall distance that the HDMI signal will need to travel is over 10ft. Due to the nature of HDMI signals, amplification is necessary to warrant the video quality and reliability. (Without amplification, there may be occasional blackouts or blinking effects) With this amplification feature, your video display can be extended up to 2,300 ft using our fiber optical HDMI cables.
3. HDMI (High Definition Multimedia Interface) v 2.0 UHD2-140 is consisting of HDMI input and output ports, and it is conforms to HDMI 2.0 standard.
4. HDCP 2.2 (High-bandwidth Digital Content Protection) Compliant Our HDMI distribution amplifiers are fully HDCP compliant. Many video sources such as Blu-ray players and Satellite/Cable Receivers are HDCP encrypted. For these video sources to be displayed correctly, HDCP compliant devices (e.g., TV, HDMI Switch, distribution amplifier) are required.
5. 4 HDMI outputs from a single HDMI source
6. Supports resolutions up to 4K@60Hz 4:4:4
7. Supports HDR (High Dynamic Range) formats
8. High bandwidth support – up to 18 Gbps
9. Supports BT.2020 color representation
10. Auto-EDID management – factory default settings and EDID emulation
11. CEC pass-through (output #1)
12. Active input & output LED indicators

Video Connection

1. Turn off the whole system before connecting.
2. Connect your video source’s HDMI output port to the UHD2-140’s HDMI input port using standard HDMI cables (not included).
3. Connect your HDMI display’s HDMI input port to UHD2-140’s HDMI output port.
4. Plug the 5V power supply to UHD2-140
5. Plug the 5V wall mount power supply into the wall outlet.
6. Turn on UHD2-140
7. Turn on your monitor
8. Turn on your video source.

PureLink UHD2-140 provides Auto EDID management system; easy and fail safe way to handle EDID, via pre-loaded factory default 1080p 2ch and EDID emulation.

What's EDID?

Extended Display Identification Data (EDID) is an information set that digital display provides to describe its capabilities to a Video source. Video source will know what kinds of displays are connected and it will determine which resolution to Output according to the EDID information received from the display. The EDID normally includes manufacturer name and serial number, sets of capable resolution including native resolution, supported timing, pixel mapping data (for digital displays only) and etc.

In a digital connectivity environment; in order to support the maximum resolution of connected monitor, EDID handshake is critical because improper EDID handshake between sources to the display will result in no image on the display.

EDID handshake may sound simple; however, with multiple peripheral devices within the chain, display's EDID information easily get lost or blocked while it is traveling to the source device.

UHD2-140 provides Auto EDID management system to meet today’s sophisticated digital connectivity integration environment. There is an EDID setting DIP switch on the front of the unit;

Note: Example of “down” position combination
If DIP switch 1,2,3 are down position, and then press “SAVE” button, the unit will analyze EDID of output 1,2,3’s connected displays and create a new unified EDID to support all three monitors screen resolution.
