ATEN VS4812 2-Port True 4K HDMI Splitter
PRODUCT DESCRIPTION
ATEN VS4812 2-Port True 4K HDMI Splitter - 2 Years Local Warranty
One Source, Two True 4K Screens
The VS4812 mirrors one HDMI source to two displays at up to 3840 x 2160 @ 60Hz with full 4:4:4 colour – ideal for a TV plus a projector, a lobby screen plus a monitor, or a presenter display plus an audience screen.
HDR10+ and HDCP 2.2
18 Gbps bandwidth carries HDR10+, 3D and Deep Color, and HDCP 2.2 compatibility means protected streaming and Blu-ray content plays on both outputs. Audio passes through in LPCM 7.1, Dolby Digital and DTS-HD Master Audio.
EDID Sync Smart Display Optimisation
EDID Sync automatically optimises the output resolution for the connected displays to prevent blank screens or mismatched formats. A pushbutton turns HDMI output 2 on or off.
Tiny and USB-C Powered
At 6.1 x 5.65 cm and 30 g, the ATEN essentials VS4812 hides behind a TV or desk, with accent lighting and USB-C power (Type-C to Type-A cable included).
