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.

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.
EDID Management
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 a 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.
