- Scaler* – supports video upscaling to 4K for display A and downscaling to 1080p for display B
The VP1421 is a multi-in-one presentation switch that integrates a video matrix, True 4K scaler, HDBaseT extender, audio DSP, and analog-to-digital converter functions into a single compact enclosure, ideal for meeting rooms and educational spaces.
True 4K, HDR Visual Clarity
Supports resolutions up to 4096 x 2160 @ 60Hz (4:4:4) and HDR to deliver vivid content in every presentation.
Smooth AV Switching Scaled to Perfection
Connect up to 4 sources (1 HDBaseT, 2 HDMI, 1 VGA), smoothly switch between them and display contents scaled perfectly to True 4K and 1080p simultaneously.
HDBaseT Extended Transmission over One Cable
Simplifies cabling and transmits AV, power, and bi-directional RS-232 and IR control signals up to 140m via Cat 6/6a or ATEN 2L-2910 Cat 6 cables (applying both HDBaseT input and output ports).

Built-in Advanced Audio DSP
Supports microphone input with selectable 48V Phantom Power and allows microphone input to be mixed with program audio and embedded into display output while automatically reducing program audio to enhance speech audibility.
Flexible Audio Embedding/De-Embedding
Supports stereo audio embedding into HDMI output or separation to Audio Line Out and Optical Audio Out. Extract HDMI and HDBaseT audio to different audio outputs as well to ease adaptation to you preferred audio setup.
Versatile Control, Streamlined Operations
Control via front-panel pushbuttons, IR remote, web-based GUI and any control interface via RS-232, Ethernet, and Contact Closure to streamline your operations.

The ATEN VP1421 is a multi-in-one presentation switch that integrates a video matrix switch, 4K scaler *, HDBaseT extender, audio DSP, and analog-to-digital converter functions into one compact device that easily mounts under a table or in a rack. With four analog/digital inputs to one HDBaseT and one HDMI True 4K outputs, it is designed to boost the efficiency and impact of professional presentations.
With streamlined control from front-panel pushbuttons, IR remote controller, RS-232, and web-based GUI via Ethernet, the VP1421 reduces not only system device count, but also lowers operation complexity. It is suitable for all meeting spaces and education environments, such as huddle rooms, classrooms, training rooms, or any other presentation setting, such as in exhibition galleries or hotels.
Note : The VP1421 scaler only supports upscaling 1080p to 4K for display A, and downscaling 4K to 1080p for display B. Other resolution scaling is inapplicable.
