1x4 HDMI Splitter with MRO

The J-Tech Digital JTECH-4KSP4 distributes a single HDMI source to four displays simultaneously. It supports 4K 60 Hz 4:4:4 video with HDR10 and Dolby Vision pass-through. HDCP 2.3 and 2.2 compliance ensures compatibility with modern streaming devices and consoles. Multi-Resolution Output downscales 4K to 1080p per output while keeping native 4K on capable screens.

Installers with mixed-resolution displays

This unit suits systems where newer 4K panels share a source with older 1080p displays. The downscaler works independently on each output so no screen forces a lowest-common-denominator resolution. It does not downscale to 720p, change progressive to interlaced, or strip HDR metadata. Buyers needing more than four outputs or 720p conversion should look at a different solution.

Desktop installation with external power

The splitter measures 6.7 x 9.3 x 9.4 centimetres and weighs 0.159 kg, fitting easily on a shelf or behind a display. A supplied power adapter connects to the barrel jack; no drivers or software are required. EDID priority follows Output 1 then Output 2, so connect the most capable display first. Common issues arise when cables exceed reliable HDMI 2.0 lengths or when the priority display is powered off during boot.

Questions about this item

What HDMI cables do I need to connect my 4K source and four displays to this JTECH-4KSP4?

You need five HDMI cables rated for 18 Gbps bandwidth — one from your source to the single input and one from each of the four outputs to a display — all supporting HDMI 2.0 and HDCP 2.3 to pass 4K 60 Hz 4:4:4 HDR10 or Dolby Vision.

Will this splitter downscale 4K HDR content to 1080p while keeping HDR metadata on my older 1080p TV?

No — the MRO downscale function converts a 4K input to 1080p but does not change the scan type or downscale HDR metadata such as HDR10 or Dolby Vision, so the 1080p display will receive an SDR 1080p signal.

How can I confirm the EDID copy has selected the correct settings after I connect my displays?

Power on the splitter and displays; the unit copies EDID from Output 1 first, then Output 2 if Output 1 is absent, so check that Output 1 shows the highest resolution and HDR format your source supports and that all four screens display a stable image.
