HDMI splitter ATEN khsplit4f 1-to-4 ports 4Kx2K@60Hz

ATEN khsplit4f is an HDMI 1-to-4 splitter that duplicates a single HDMI source to up to four displays. It supports resolutions up to 4K x 2K at 60Hz, transmits both video and audio, and includes an active signal amplifier to maintain signal integrity over longer cables. The unit comes in a compact black metal housing and is powered by an external 5V adapter.

Advantages

The splitter supports HDMI 2.0 and HDMI 1.4 standards, HDCP 2.2 and 3D formats, and wide audio standards including Dolby and DTS variants. It provides LED indicators for power and per-port signal status, a bandwidth up to 600 MHz and a maximum data rate of 6 Gb/s. With its active amplification the device can drive HDMI cables up to about 8 m (using quality copper cables sized appropriately for the resolution).

Suitable for

How to use

Connect an HDMI cable from the source device (PC, notebook, DVD, set-top box, etc.) to the HDMI input on the splitter. Connect up to four displays to the HDMI outputs. Plug the supplied power adapter into a 230V mains outlet and connect it to the splitter's DC 5V socket. If the displays do not show video immediately after connection, wait approximately 30 seconds for the HDMI signal to be detected and synchronized.

Usage recommendations

Use high-quality HDMI cables with proper copper conductors and adequate conductor cross-section for the chosen cable length and resolution. For best results at 4K/60Hz keep individual cable runs within recommended lengths (the splitter's amplifier supports cables up to around 8 m depending on cable quality).
