8-Way 4K HDMI Media Player

This 4K multimedia player drives eight HDMI outputs simultaneously from a single Android 4.4 device. It targets digital-signage installers and retail-display operators who need identical 4K content across multiple screens without a PC. The unit decodes H.265 and H.264 at 4K 30 Hz and MPEG-4 at 1080P 60 Hz for smooth playback. Wireless networking and IR control simplify deployment in store-window or showroom environments.

Upgrade from single-output players

Replaces standalone media boxes that only feed one display, eliminating the cost and cabling of eight separate units. The jump is worth it when a venue requires synchronised 4K video walls or duplicated promotional loops across many televisions. Buyers who need independent content on each screen or resolutions beyond 4K 30 Hz should look elsewhere. The Android 4.4 platform also limits modern app compatibility for interactive kiosk projects.

HDMI 1.4 bandwidth ceiling

HDMI 1.4 caps output at 4K 30 Hz with a 300 MHz pixel clock, so higher refresh rates or 10-bit colour are unavailable. Cable runs are restricted to eight metres per port using AWG26 cable, limiting placement flexibility in large installations. Audio extraction relies on a single SPDIF port rather than multi-channel HDMI audio. The DDR3 memory and older Android version constrain future codec support and security updates.

Questions about this item

Does the 8-way HDMI output need any special cable length or gauge?

Standard AWG26 HDMI cables are supported; input and output runs each up to 8 metres.

What is the step users often miss when setting the 4K 30 Hz resolution on this Android 4.4 box?

After powering on, use the IR remote or a USB mouse to open the resolution menu and select 4K x2k@30Hz; the setting does not apply automatically.

Which storage media can be swapped while the player is running?

The Micro SD slot and the two USB 2.0 ports allow hot removal of TF cards and flash drives for video playback or firmware upgrades.
