Data Sheet



With the rapid development of HDBaseT technology, ATEN has released the new VM3909H HDMI HDBaseT-Lite Matrix Switch. The switch extends uncompressed 4K / Full HD digital video, audio, IR and power via HDBaseT technology through a single Cat 6a cable up to 40/70 meters.
When the VM3909H is combined with VE805R receivers, it supports both ATEN Seamless Switch™ technology and Video Wall functionality. ATEN’s exclusive Seamless Switch™ technology employs an FPGA graphics processor to ensure continuous video streaming, real-time control and stable signal transmission across all sources. The Video Wall functionality allows you to create 18 video wall profiles for custom screen layouts through an easy-to-use web interface. The Power over HDBaseT (POH) feature provides an ingenious way to power the VE802R receivers through the Cat 5e cable without the need of using an additional power supply.

  • Supports 9 HDMI inputs and mirrored 9 HDMI and HDBaseT outputs
  • HDBaseT Connectivity – connects HDMI displays over a long distance via one Cat 5e/6/6a cable
  • HDBaseT Anti-jamming – resists signal interference during high-quality video transmission
  • Power over HDBaseT (POH) – supplies power over a long distance from the switch to a receiver over a single Cat 5e/6/6a cable* / **
