> Supports multi-format 4 Inputs – 2 HDMI, 1 HDBaseT, and 1 VGA inputs

> 1 HDMI and 1 HDBaseT outputs

> Audio embedding – stereo audio can be embedded into display output or separated to stereo line out and optical audio outputs

> Audio de-embedding – HDMI/HDBaseT audio can be extracted to stereo line out

> Built-in 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

> Automatically reduces program audio when a microphone signal is detected

> Auto switching – automatically detects and switches to a new source as soon as it is connected

> Superior video quality – True 4K resolutions up to 4096 x 2160@60Hz (4:4:4) (HDMI) / 4096 x 2160@60Hz (4:2:0) (HDBaseT)

> Supports 4K HDR

> Scaler – supports video upscaling to 4K for display A and downscaling to 1080p for display B

> EDID Expert – automatically selects the optimum EDID settings for smooth power-up, high-quality display, and the best video resolution across connected devices

> HDMI (3D, Deep Color, 4K); HDCP 2.2 compliant

> Multiple control options – flexible control via front-panel pushbuttons, IR remote control, RS-232, and web-based GUI through Ethernet

> View and control via ATEN Video Presentation Control App in a swift and agile way

> Bi-directional RS-232 and IR channel – allows AV device control over HDBaseT connection without additional cabling

> Supports stand-by mode for power saving and fast waking up

> Consumer Electronics Control (CEC) support

> Built-in Contact in and LED out for keypad control using VPK104 Contact Closure Remote Pad

> Long-distance transmission – transmit digital AV signal, bi-directional RS-232, and IR control signals up to 140m via Cat 6/6a or ATEN 2L-2910 Cat 6 cables

> Power over HDBaseT (POH) – remote powering over existing communication cable with selectable powering device

> Note: This is achieved using both the HDBaseT In and the HDBaseT Out ports on the VP1421, each extending the transmission up to 70m
