Product Description

The ATEN VS4812 is a compact 2-port True 4K HDMI splitter designed for home entertainment systems, mirrored dual-display workstations and professional audiovisual installations.

It distributes the audio and video signal from one compatible HDMI source to two HDMI displays simultaneously. Compatible source devices can include laptops, desktop computers, game consoles, media players, set-top boxes and Blu-ray or DVD players.

The splitter supports True 4K resolutions up to 3840 × 2160 at 60Hz with 4:4:4 chroma sampling. It also supports HDR10+, 3D formats, Deep Color and HDCP 2.2 for use with compatible source equipment, displays, content and HDMI cables.

ATEN EDID Sync technology automatically optimises the output resolution according to the connected displays, helping to reduce compatibility and display start-up issues.

Compatible audio formats include LPCM 7.1, Dolby Digital and DTS-HD Master Audio. A front-panel pushbutton allows HDMI output 2 to be enabled or disabled without disconnecting the display.

The VS4812 is an HDMI splitter and not an HDMI switch. It mirrors the same HDMI source across both connected displays and does not provide separate content to each display.
