2-Port HDMI 2.0 Splitter for 4K Displays

The StarTech ST122HD202 duplicates a single HDMI source across two screens at up to 3840x2160 resolution and 60Hz refresh. It handles 18Gbps bandwidth with 4:4:4 chroma subsampling and HDR support. Audio pass-through includes 7.1 surround sound with Dolby True HD and DTS HD Master Audio. Ideal for digital signage, meeting rooms or dual-monitor workstations needing identical output.

Compact metal enclosure with EDID emulation

The unit measures 3.90" x 2.20" x .70" and weighs 5.6 oz, fitting easily behind displays or in equipment racks. One HDMI female input connects the source while two HDMI female outputs feed the screens. EDID emulation maintains continuous handshake so displays stay active when one is powered off. A universal power adapter with NA, EU, UK and ANZ plugs is included for immediate deployment.

Replaces basic 1080p splitters

Upgrading from a 1920x1080 limited splitter removes the resolution ceiling for modern 4K panels and preserves full chroma detail. The jump is worth it when source equipment outputs 2160p60 and both displays must show pixel-for-pixel identical content without driver installs. Not suited for setups requiring independent screen content or more than two outputs.
