HDP901 video processing and LED screen splicing
The Huidu HDP901 combines source switching, image processing and splicing for LED display systems. It supports seamless channel switching, picture-in-picture (PIP) and chroma key, with two splicing channels and one monitoring output. Multiple processors can be used for multi-machine splicing.

Output-resolution note: the V1.2 feature list gives 7840 × 640 at 60 Hz and 4608 × 1152 at 60 Hz, while its output table lists 7680 × 640 at 60 Hz among the custom A+B formats. These conflicting wide-format values are not interchangeable; verify the required mode before specifying a wide screen.
Input selection and installation
The advertised 11-input count includes the optional SDI input. Composite video and VGA are analog inputs, so the full set should not be described as eleven digital inputs. Confirm the SDI configuration if it is needed for your source equipment.
Four sending-card installation positions provide space for integration. This is a mounting provision, not confirmation that four sending cards are supplied. Check the order configuration against the sending cards and receiving cards used in the display.
