One HDMI source. Two screens that need to look identical. And you're tired of the resolution mismatch that leaves one monitor stretched while the other sits at native 4K.
The VS4812-AT shares one True 4K signal across both displays with EDID Sync handling the handshake so you skip the blank-screen chase. HDR10+, 3D, Deep Colour and HDCP 2.2 all pass through without a hitch. Audio covers LPCM 7.1, Dolby and DTS-HD Master Audio, so your receiver gets the full mix.
There's a pushbutton on the unit that toggles output 2 on or off. Handy when you only need one screen during a meeting and want the second dark without unplugging anything.
Slim enough to sit behind a monitor or tuck onto a shelf. Accent lighting means you can actually find it in a dark room
