SPECIFICATIONS
INSTALLATION/OPERATION INSTRUCTIONS
2. Connect the HDMI cable (High Speed rated) between the 4Kx2K source (Media
Player, Satellite Receiver, etc.) and “HDMI Input” port of the UH4-4K/UH8-4K
3. Connect the HDMI cables from the outputs of the distribution amplifier to the
inputs of the UHDTV. Connect a quality brand TV to port 1 output.
4. Power up the UH4-4K/UH8-4K and the UHDTV connected to HDMI output
number one on the amplifier. Leave the other UHDTV’s off for now.
5. Turn on power to the source device. The UHDTV connected to output number one
should have picture and sound within 5 seconds
.
6. Turn on power to the remaining UHDTV’s.
7. Install a cable tie around the HDMI cable and chassis tab, if desired, to prevent
accidental unplugging of the HDMI cables. See picture above.
NOTES:
1. All UHDTV’s connected to the UH4-4K/UH8-4K should be capable of the same resolution.
2. Always connect the first UHDTV to output number one on the UH4-4K/UH8-4K first.
This is necessary for the Electronic ID to be read properly by the source.
3. For optimum performance, try to use HDMI cables no longer than 5 meters in length, and
4Kx2K approved (High Speed Rated).
