A powered UGREEN 1-in-4 HDMI splitter that takes one HDMI source and mirrors the same picture and sound onto four HDMI displays at up to 4K at 30Hz.
This is a UGREEN HDMI splitter with one HDMI input and four HDMI outputs, all full-size HDMI Type-A female ports.
You plug one source into the input, such as a laptop, media player or camera, and the splitter duplicates that single feed out to four screens so every display shows exactly the same image and audio.
It supports up to 4K at 30Hz, or 1080p at 60Hz for smoother motion, and it passes HDCP through so protected content keeps playing on HDCP-capable displays.
Because it is an active device, it runs from an included power adapter over USB or DC, which keeps the signal clean across all four outputs.
It is important to know that this is a splitter, not a switch. A splitter copies one source to many screens, so all four outputs are always the same picture.
It does not let you pick a different feed for each screen, and it does not select between several sources the way a switch does.
Every output runs at the source resolution, so the setup works best when the four displays are broadly similar.
These specifications are the typical values for this UGREEN 1-in-4 model and are pending a physical check of our actual unit before they are confirmed, so treat the numbers as a reliable guide rather than a measured datasheet.
