1x4 HDMI Splitter for 4K 30Hz Distribution

This Jansicotek splitter takes a single HDMI source and duplicates it to four identical outputs at up to 3840 x 2160 resolution and 30 Hz. It transmits audio and video simultaneously without quality loss and supports 3D content. The unit is designed for installers and AV enthusiasts who need to drive multiple displays from one player, set-top box or console.

Replaces basic switches and single-output cables

Unlike a switch that selects between several sources, this device only duplicates one incoming signal to four screens. The upgrade is worthwhile when you need simultaneous viewing on all connected displays rather than switching between them. It supports HDCP 1.4 for protected content and handles resolutions down to 408i and 576i through 1080p. Buyers who need to route four different sources to one screen cannot use this product.

Fits into a rack or desktop AV chain

The metal chassis provides durable, corrosion-resistant ports for stable signal transmission. A 5 V 2 A power adapter is included in the box. Total cable length should stay under 20 m at 4K (10 m input plus 10 m output) or under 30 m at 1080p (15 m each side). All four output devices must share the same resolution for correct operation.

Questions about this item

What clearance is needed for the metal HDMI splitter box and its 5V/2A power adapter?

The splitter is a metal box with one HDMI input and four HDMI outputs; the included 5V/2A AC adapter plugs into mains power and connects to the unit via its DC jack.

Which cable-length limits must be observed during installation, and what is the common mistake?

At 4K resolution keep total HDMI cable length under 20 m (10 m input plus 10 m output); at 1080P keep it under 30 m (15 m each side). A common mistake is exceeding these lengths and losing signal.

When will the 5V/2A power adapter need replacement, and how can I tell?

Replace the adapter if the splitter stops powering on, shows intermittent signal drop-outs, or the adapter becomes excessively hot or emits a burning smell during use.
