Overview
Route one HDMI source to eight screens at once, with each receiver fed by a single Cat6, Cat6a, 7 or 8 cable run from the transmitter. The transmitter carries the signal and the power down that same cable, so receivers need no local adapter. An extra HDMI output on the sender feeds a nearby monitor, and IR commands travel back to the source over a dedicated channel.
Running video across a building usually means long HDMI cables or a matrix, and this kit replaces both with network cabling and a single powered head end. The loop output lets a local screen mirror the feed without a second splitter. The limitation is reach: the higher resolutions travel shorter distances than the lower ones, so plan runs around the cable and resolution you actually use.
Who it's for
Places where one player, console or receiver has to reach screens in several rooms, and the cable path is already in place or can be pulled. Skip it when every display needs a different signal, or when runs exceed the distances the kit supports at 4K.
Pros and cons
- Eight receivers feed eight displays at once
- Power travels over the network cable
- Loop out holds a local monitor fed
- IR pass back controls the source remotely
- 4K reach is shorter than 1080P reach
- No audio extraction or separate audio output
- Requires one power adapter at the transmitter
- IR control only, no network or app control
Performance notes
Distance and cable grade decide the picture more than anything else: the signal rides twisted pair from a single powered transmitter, and each receiver rebuilds it for its display. Higher resolutions consume more of that budget, so a run that holds at lower resolutions may not hold at the top one. The IR channel carries remote commands back to the source separately from the video.

Frequently asked questions
Will the Orei UHD18-EX115-K work with my existing Cat6 cabling and displays?
It is built for Cat6, Cat6a, 7 and 8 network cable, and each of the eight receivers outputs HDMI to a display. The transmitter also has one HDMI loop output for a local monitor. Displays that need HDCP 2.2 handshaking are covered by the kit's HDCP support.
What is included with the Orei UHD18-EX115-K?
The box holds one transmitter, eight receivers, one power adapter, one IR blaster cable, eight IR receiver cables and a user manual. Only the transmitter end needs the power adapter, since the receivers draw power over the network cable.
How far can the Orei UHD18-EX115-K send a 4K signal?
Over Cat6 or Cat7 cable the 4K signal reaches up to 115 feet, while a 1080P signal reaches up to 165 feet. Plan each run against the resolution you intend to use at that display.
Can I control the source device from a remote screen with the Orei UHD18-EX115-K?
Yes. The kit passes IR back from the receiver side to the source over a dedicated DDC channel, supporting 20 to 60Hz IR, using the supplied IR blaster and receiver cables. That lets a DVD player or other HDMI source be operated from a remote location.
Does the Orei UHD18-EX115-K need a separate power supply at every screen?
No. Power travels over the LAN cable from the transmitter, so the receiver side needs no adapter. The transmitter uses one power adapter, supplied with a US plug, and an adapter or converter is provided for international use.
