A powered splitter for feeding two screens from one source, with retiming that holds long cable runs clean. It passes a single input only, so it cannot mix two sources or switch between them.

Overview
A powered splitter takes one HDMI signal and drives two displays from it at the same time. Signal retiming rebuilds the stream on the way out, and each output runs on its own, so a screen can be left off or unplugged without disturbing the other.
Feeding two televisions from one player or console usually means a splitter, and this one carries Ultra HD, 3D and deep color through without asking the source to do extra work. The constraint is direction: it sends one input to two outputs and never combines or selects between sources.
Who it's for
Two displays in different rooms showing the same feed is the case this handles, with the powered design covering longer cable runs. Shoppers who want to choose between a game console and a streaming box on one TV need a switch instead.
Pros and cons
- Two outputs work independently of each other
- Signal retiming rebuilds the stream on output
- Carries Ultra HD, 3D and deep color
- Handles DTS-HD, Dolby-True-HD and LPCM7.1 audio
- No switching between multiple inputs
- 3D needs every connected unit to support it
- Deep color needs source and display support
Performance notes
Retiming is the working part: the splitter rebuilds the HDMI stream rather than passing it through, which is what holds picture quality together over long cable runs. Audio and video formats travel untouched, but the result depends on the source and both displays agreeing on the same format, so a 3D or deep color signal only shows when every unit in the chain supports it.

Frequently asked questions
Is the J-Tech Digital JTD0102/4K splitter limited to certain screen sizes?
Screen size plays no part. What matters is the signal: the splitter handles up to 3840 x 2160 and 3D, so any display that accepts those formats and the HDMI 1.4 standard works, whatever its diagonal.
Can both outputs run at the same time?
Yes. The two outputs are independent, and the splitter continues working when only one display is on.
What happens to 3D and deep color through this splitter?
Both pass through only when the source and every connected display support them. A 3D source needs all units on the outputs to be 3D capable.
How long can the HDMI cables be?
Input runs reach up to 80 ft and output runs up to 50 ft with AWG26 HDMI cable. Signal retiming holds quality intact across those distances.
Does the J-Tech Digital JTD0102/4K switch between sources?
No. It takes one HDMI input and sends it to two outputs. Choosing between a console and a streaming box on one TV calls for a switch, not this splitter.
