HDP703 LED video processor with PIP and source switching
The Huidu HDP703 scales and switches live video for LED screen installations. It accepts digital and analog sources, supports picture-in-picture and provides DVI/VGA video outputs for the display system. It is suitable for stage, rental and exhibition setups using compatible LED sending hardware.
Image control for live displays
Use cut or fade transitions when changing sources, freeze the output while preparing a change, and crop a selected area or restore a full-screen picture. Four user preset groups store settings for repeat use. The specification also describes equal and unequal splicing across multiple processors.

Frequently asked questions
Does the HDP703 support picture-in-picture?
Yes. The standalone specification supports PIP and POP, including adjustment of the overlay size, position and border. The original description of a single picture does not capture these supported modes.
How many inputs are standard?
The HDP703-specific document lists six standard video inputs: one DVI, one HDMI, two VGA and two CVBS. Optional SDI brings the total to seven. Confirm the fitted SDI option if required.
Is the output capacity 2.65 million pixels?
The original listing gives 2.65 million pixels, and the specification lists 2304 × 1152 at 60 Hz. However, its custom-resolution paragraph states 1.3 million pixels. Confirm a custom canvas against the actual device and firmware instead of applying the largest preset to every mode.
Does it replace an LED sending card?
The processor outputs video through DVI/VGA. Use suitable LED sending and receiving hardware for the screen; the presence of video outputs alone does not provide direct LED module control.
Which PDF should I use for the input count?
Use the HDP703-specific V1.2 specification for the model’s input list. The linked shared HDP703/HDP602 manual contains different channel counts; match its instructions to the actual front and rear panels.
