A704 receiving card with display processing functions
The Mooncell A704 is a four-interface HUB75E receiving card for LED cabinets. Alongside AutoLED configuration and pixel-level calibration, it supports 18Bit+, independent RGB gamma adjustment and bright/dark seam adjustment for display setup.
HDR, 3D and low-latency operation have specific source, controller or driver requirements. The table keeps those conditions alongside the features and separates conventional-driver loading from PWM-driver loading.

Frequently asked questions
What is the A704 loading capacity for conventional and PWM drivers?
The specification lists 256 × 256 pixels for conventional drivers. With PWM drivers, maximum loading and brightness-corrected loading are 512 × 256, while chromaticity-corrected loading is 256 × 320.
Does A704 support HDR10 and HLG by itself?
HDR operation requires a compatible high-capacity independent controller and an HDR10 or HLG source. The receiving card is part of that display system; its HDR feature does not replace the required source and controller.
What is required to use the A704 3D function?
The manual calls for a receiving-card frame rate of 120 Hz and an independent controller that supports 3D. Enable the 3D function and set its parameters in the software or controller panel.
Is one-frame latency guaranteed for every module?
No. The specification qualifies the low-latency function for LED modules whose driver ICs have built-in RAM. It describes latency at the receiving-card end, not a guaranteed end-to-end delay for the complete video system.
What does 18Bit+ do?
The manual describes 18Bit+ as a software-enabled function that increases grayscale by four times to address grayscale loss at reduced brightness and low-gray correction artifacts. Check the display configuration and compatible components when applying it.
