Signal Distribution

The StarTech ST128HD20 is an eight-port HDMI 2.0 splitter that takes a single 4K 60Hz source and sends it to up to eight displays simultaneously. It supports HDR and 7.1 surround sound audio pass-through for a complete AV signal path. Mounting hardware is included for rack or wall installation.

Ideal Installations

This unit suits installers who need identical 4K 60Hz 4:4:4 content on every screen in a digital signage, classroom or conference room setup. It is not for users who require independent images on each output or who need to switch between multiple sources on a single display.

Bandwidth Limits

The 18Gbps bandwidth handles 4K 60Hz with full chroma subsampling and HDR without compression. It also runs 4K 30Hz and 1080p displays through backwards compatibility. The splitter cannot pass video formats that exceed the 18Gbps ceiling or audio formats beyond 7.1 channels.
