ATEN VS5812 2-Port 8K HDMI Splitter 7680 x 4320 video accessory

SKU CH-JKN9-BC5WE MPN VS5812

Splits one 8K HDMI source to two displays at 7680 x 4320 resolution with 59.06" maximum operating distance

  • Delivers pristine 8K visuals at 7680 x 4320 resolution
  • Splits one source to two displays simultaneously
  • Supports 4K at 120Hz for smooth gaming motion
  • Maintains signal integrity up to 59.06 inches distance
  • Ensures HDCP 2.3 compliant playback on all outputs

Single-Source 8K Splitter

The ATEN VS5812 distributes one HDMI input to two identical outputs at resolutions up to 7680 x 4320. It supports 8K at 60 Hz and 4K at 120 Hz with HDR10+, Dolby Vision, VRR and ALLM. The unit handles HDCP 2.3 and uses EDID Sync to maintain stable handshakes across both displays.

Dual-Display Installations Only

This splitter suits users who need the same 8K signal on two screens, such as a projector and a TV or dual monitors in a studio. It does not extend a desktop across monitors, so buyers who want independent content on each display should look at a matrix switch or a graphics card with multiple outputs.

Plug-and-Play HDMI

Connect the source to the single HDMI input and the two displays to the HDMI outputs; no drivers or software are required. The 59.06-inch maximum operating distance means long cable runs beyond that length may lose signal integrity, so keep cable lengths within the specified limit for reliable operation.

Questions about this item

What HDMI source do I need to feed the VS5812's single input for 8K output?

Connect any device with an HDMI 2.1 port — PC, notebook, game console or media player — that can output 7680 x 4320 at 60 Hz or 4K at 120 Hz.

Will my older 4K 60 Hz monitor work on one output while the other runs 8K?

Yes. EDID Sync™ reads each display and sends the highest common resolution, so a 4K 60 Hz screen and an 8K 60 Hz screen can run simultaneously.

How do I confirm HDR10+ and Dolby Vision are active after I connect everything?

Play HDR10+ or Dolby Vision test content; both displays should show the correct HDR badge and report 10-bit or 12-bit Deep Color in their on-screen menus.
