8K HDMI Splitter 1 in 4 Out

This new Astro Gaming accessory duplicates a single HDMI 2.1 source across four displays simultaneously. It serves gamers and home-theatre users who need identical 8K or high-refresh 4K output on multiple screens. The 2-in-1 design adds HDMI audio extraction for external sound systems.

HDMI 2.1 bandwidth and EDID control

The splitter passes 8K at 60 Hz, 4K at 144 Hz, 4K at 120 Hz and 1080p at 240 Hz with 4:4:4 chroma, VRR, ALLM, HDR10 and HDCP 2.3. A five-position toggle provides 22 EDID presets to force the required resolution and feature set on every connected display.

Four-display mirroring with audio breakout

It comfortably drives four monitors or TVs in mirror mode at the highest listed refresh rates while sending Dolby Atmos, DTS:X, TrueHD or PCM 5.1 and 7.1 to a receiver via the HDMI audio port. It runs out when a setup demands different content on each screen or more than four outputs.
