HDP902 three-channel LED video splicing processor
The Huidu HDP902 processes multiple live video sources for spliced LED displays. It provides three splicing channels and a separate monitor output, with up to 7.95 million pixels of combined output at 60 Hz. Use it for image switching, scaling and equal or unequal screen layouts.
Source switching and layout control
Connect DVI, HDMI, VGA or composite sources, with SDI available as an option. The processor supports custom input EDID, picture-in-picture, cross-channel window positioning, cropping and screen freeze. Front-panel controls and RS232 provide configuration access, and saved scenes can be recalled for repeated layouts.
Program video is sent through DVI connectors to compatible LED sending cards. The processor has four internal card-mounting positions; check the actual sending-card configuration required for your screen.

Frequently asked questions
How many independent output channels does the HDP902 provide?
It provides three splicing channels, each with two DVI program-output connectors, plus a separate DVI monitoring output. Six program connectors do not mean six independently processed splicing channels.
What is the total output pixel capacity?
The specification states 2.65 million pixels per channel at 60 Hz and 7.95 million pixels across three channels. Maximum width and height are separate limits and must remain within that total capacity.
Is SDI standard on every HDP902?
No. SDI input and SDI loop output are listed as optional. Confirm the fitted input configuration if your source is an SDI camera or other SDI device.
Does the HDP902 connect directly to LED receiving cards?
Its program outputs are DVI and are used with suitable LED sending cards. The chassis provides four internal sending-card mounting positions; mounting space does not establish which cards are included.
Can I save layouts and switch between sources?
Yes. The HDP902 supports preset saving and recall, source switching, image scaling, cropping, freeze and picture-in-picture operation. The English specification mentions both eight stored preset sets and four front-panel preset groups; confirm the preset workflow for the supplied version.
