MVB12 multi-picture splicing and LED sending
The Mooncell MVB12 integrates video splicing, processing and LED sending for stage, conference, event and exhibition screens. Twelve Gigabit Ethernet outputs support 7.8 million pixels in total, with up to eight pictures that can be overlaid, moved and scaled.
The linked specification includes a V3.2 update history. Its input overview and rear-panel table list different connector configurations, so the table below distinguishes those descriptions instead of assuming every unit has the additional HDMI 2.0 and DP ports. Confirm the actual rear panel before planning a 4K connection.
Technical specifications
| Parameter | Specification |
|---|---|
| Model | Mooncell MVB12 2-in-1 video splicing and LED sending processor |
| LED outputs | 12 × RJ45 Gigabit Ethernet, 1000BaseTX |
| Pixel capacity | 7.8 million pixels total; 650,000 pixels per port |
| Per-port width / height limits | 3840 pixels wide or 3840 pixels high, within the per-port pixel capacity |
| Whole-unit width / height limits | 30,720 pixels wide or 30,720 pixels high, as listed in the V3.2 basic parameter table; subject to total pixel capacity |
| Simultaneous pictures | Up to 8, with overlay, roaming and scaling |
| Inputs in original listing and PDF overview | 3 × HDMI and 1 × DVI |
| Detailed input-table qualification | The PDF rear-panel table additionally lists 1 × HDMI 2.0 and 1 × DP 1.2. These are absent from its overview and the original page, so the exact input configuration requires hardware-revision confirmation. |
| HDMI formats in detailed table | 3 HDMI 1.4 inputs: 1920 × 1080/60 Hz. The separately listed HDMI 2.0 input: 4096 × 2160/60 Hz, subject to the input-configuration note above. |
| DVI signal | VESA DVI-D digital signal only; custom EDID |
| DP format in detailed table | The separately listed DP 1.2 input supports 4096 × 2160/60 Hz, subject to hardware-revision confirmation. |
| Overall input claim in feature list | 3840 × 2160/60 Hz and maximum 7680 × 1080/60 Hz, with custom resolution; the feature list does not assign these formats to a specific connector. |
| Window controls | Source switching/scaling, crop, partial enlargement, adjustable position and size |
| Receiver support | Mooncell receiving cards and multifunction cards |
| Control | 100 Mbps LAN configuration interface; RS232 is marked reserved |
| 3D-SYNC | Reserved; not supported at the time of the linked specification |
| Front-panel controls | LCD, knob, MENU/ESC, BLACK, LOCK and scene-recall number keys; engineering time lock |
| Power | 100–240 VAC, 50/60 Hz; rated 36 W |
| Environment | −20 to 70°C; 10–80% RH, non-condensing |
| Dimensions / net weight | 472 × 290 × 64 mm (L × W × H); 2.8 kg ±5 g |

Frequently asked questions
How many pictures can MVB12 display?
The original listing and linked specification both state up to eight simultaneous pictures. Picture overlay, roaming, scaling, cropping and partial enlargement are described.
What is the total and per-port pixel capacity?
The PDF specifies 7.8 million pixels for the unit and 650,000 pixels per Ethernet port. Width and height limits are separate layout constraints; they do not override those pixel-count limits.
Which MVB12 connector supports 4K input?
The source documents are inconsistent about the physical input configuration. The overview lists three HDMI inputs and one DVI, while the rear-panel table adds HDMI 2.0 and DP 1.2 with 4096 × 2160/60 Hz support. Confirm the actual rear panel and revision before choosing a 4K source connection.
Does the 3D-SYNC connector mean 3D is enabled?
No. The linked specification explicitly marks 3D-SYNC as reserved and not supported at that time. The presence of the connector alone does not establish usable 3D functionality.
Can each Ethernet port be used for an independent display load?
Yes, the feature list describes independent loading on each port. Keep each port within its 650,000-pixel capacity and 3840-pixel width or height limit, and keep all outputs within the unit’s 7.8-million-pixel total.
