  • Routes one source to four displays simultaneously
  • Downscales 4K to 1080p per output automatically
  • Extracts audio via optical and 3.5mm analog ports
  • Supports HDCP 2.2 and HDCP 1.4 content protection
  • Handles 4K at 60Hz with 18Gbps bandwidth

One input to four displays

This DVDO splitter routes a single HDMI source to four screens at the same time. It handles signals up to 4K at 60 Hz with 4:4:4 colour sampling and 18 Gbps bandwidth. The unit is HDCP 2.2 and 1.4 compliant for broad content compatibility. Ideal for installers who need identical output across multiple displays.

Independent downscaling per output

Each of the four HDMI ports can downscale a 4K signal to 1080p without affecting the other outputs. Audio is de-embedded to both optical S/PDIF and 3.5 mm analogue jacks, supporting PCM 2.0, Dolby and DTS formats. Selectable Copy and Auto EDID modes simplify integration with mixed display types. The package includes the power adapter and manual for immediate setup.

Low heat and silent operation

The compact metal enclosure runs without a fan, so it adds no audible noise to a rack or desk. Power draw stays modest thanks to the efficient HDMI 2.0b circuitry. Normal use produces only gentle warmth that dissipates through the case. No special ventilation or cooling allowance is required.

Questions about this item

What resolution limit appears first when the splitter runs continuously at 4K@60Hz?

The unit supports 4K@60Hz 4:4:4 at 18Gbps and can downscale each output to 1080p, so the first limit under sustained use is the 18Gbps bandwidth ceiling for full 4:4:4 colour.

How hot or loud does the box get when it powers four displays all day?

The splitter is a compact passive-metal enclosure with no fan; it runs warm but silent during continuous operation because it draws only the included power adapter's rated current.

Which cables and power source must I already have to connect one source to four screens?

You need five HDMI cables (one input, four outputs), an optical or 3.5mm audio cable if you want extracted sound, and a mains outlet for the supplied power adapter.
