HDMI splitter ATEN VS5812, 2‑port, supports up to 8K

The ATEN VS5812 is a 2‑port HDMI splitter that duplicates a single HDMI input to two HDMI outputs while supporting resolutions up to 8K. Designed for environments where an identical high‑resolution image must be displayed on two screens simultaneously, this compact device provides consistent signal distribution and simplifies installation for meeting rooms, showrooms, control rooms and digital signage installations. The unit handles high‑bandwidth video formats and maintains image integrity across both outputs.

Advantages

The HDMI splitter delivers the same source signal to two displays without degrading image quality, preserving sharpness and color fidelity at high resolutions. Its support for up to 8K ensures compatibility with modern displays and future‑proofs installations that require very high pixel density. The device has a straightforward setup process and minimizes cabling complexity by allowing one source to feed two monitors. Stable signal distribution reduces the need for additional signal management equipment.

Suitable for

• Meeting rooms and conference halls where the same presentation must appear on multiple screens
• Retail showrooms and product displays requiring identical visuals on several monitors
• Digital signage systems that show synchronized content across two displays
• Control rooms and monitoring stations needing duplicated high‑resolution feeds
• Home theater setups where the same media source is used for multiple TVs or projectors

Key specifications

• Number of outputs: 2 HDMI outputs
• Maximum supported resolution: up to 8K
• Video formats: supports high‑bandwidth HDMI video signals including high resolution and high frame rates
• Signal distribution: duplicates single HDMI input to two identical outputs
• Physical format: compact standalone splitter suitable for rack or table placement

How to use

Connect the HDMI source device (such as a media player, laptop or AV receiver) to the splitter's input, and then connect HDMI cables from the splitter's two outputs to the displays. Power the unit from its external power supply and ensure displays are set to the correct HDMI input. The splitter automatically mirrors the source to both outputs; no additional configuration is typically required. Verify display resolution settings on the source to match the connected displays for optimal image quality.

Usage recommendations

For best results, use high‑quality HDMI cables rated for the required bandwidth to support 8K signals. Place the splitter near the source or use active HDMI extenders for long cable runs. When using mixed displays, set the source output to a resolution supported by both screens to ensure stable output on both displays.
