Know what connects where.
Connection overview. Check the requirements below for the exact ports, cable type and supported operating mode.
Share the same moment everywhere
All 4 HDMI outputs carry the selected source’s content. It is useful for screens showing one presentation, promotional loop or live feed; the source remains in control of the picture.
Match the display mix
Automatic 4K-to-1080p downscaling helps combine a compatible 4K display with Full HD screens. Resolution scaling does not guarantee HDR-to-SDR conversion or compatibility with every audio format.
Plan each output connection
Connect the source to HDMI IN and run a suitable HDMI cable from each output to a display. EDID negotiation helps establish the source format; long output runs may need a separately matched extender.
Make sure it fits your setup.
Same content
A splitter duplicates one video stream. It cannot create independent extended desktops or choose different programmes for each display.
Format support
HDMI 2.0, HDCP 2.2 and up to 18Gbps; HDR operation requires compatible equipment.
Audio compatibility
The source audio format must work with the destination devices. A splitter does not convert unsupported surround audio into stereo for every screen.

A little clarity before you buy.
Will this create an extended desktop?
No. Each screen receives the same source signal. Use independent graphics outputs or a suitable dock for extended desktops.
Can each display show a different channel?
No. Different programmes require different sources and a matrix or other routing system.
Can I mix a 4K and 1080p screen?
This model provides automatic resolution downscaling, subject to format compatibility.
