MVB20E multi-window processing and LED sending
The Mooncell MVB20E combines 4K video processing and LED control for large stage, exhibition and venue screens. It provides 20 Ethernet outputs, up to five simultaneous picture layers and ten scene templates, with picture-in-picture and independent transparency for each window.
Capacity note: the original listing and linked PDF do not give a consistent total pixel limit. The overview and basic table state 13 million pixels, the output table states 10.2 million, and the feature list contains “1300 Million Pixels.” These conflicting values are preserved with their sources below rather than converted into a single assumed rating. Confirm the hardware/firmware revision and intended layout before sizing the system.
Technical specifications
| Parameter | Specification |
|---|---|
| Model | Mooncell MVB20E 2-in-1 LED video processor |
| LED outputs | 20 Ethernet output ports |
| Per-port capacity | 650,000 pixels, per the basic parameter table |
| Total capacity — source conflict | The overview and basic parameter table specify 13 million pixels; the output-interface table specifies 10.2 million. The feature list also says “1300 Million Pixels.” These figures conflict and are not treated as interchangeable. Confirm the applicable limit for the supplied revision. |
| Tall-layout qualification | The basic parameter section says capacity decreases when height exceeds 8192 pixels, with a stated minimum of 11.98 million. This remains part of the same unresolved capacity documentation. |
| Maximum output width / height | 15,360 pixels wide or 15,360 pixels high; separate limits, subject to the confirmed total capacity |
| UHD inputs | 1 × HDMI 2.0 (HDMI3) and 1 × DP 1.2; only one of these two inputs can be used at a time |
| UHD input formats | 3840 × 2160/60 Hz or 7680 × 1080/60 Hz; custom width 7680 at 7680 × 1080/60 Hz or height 7680 at 1080 × 7680/60 Hz |
| HDMI 1.3 inputs | 2; up to 2304 × 1152/60 Hz; custom 3840 × 640/60 Hz or 640 × 3840/60 Hz; interlaced input unsupported |
| DVI inputs | 2; up to 2304 × 1152/60 Hz; custom 3840 × 640/60 Hz or 640 × 3840/60 Hz; interlaced input unsupported |
| Windows / layers | Up to 5 simultaneous pictures/layers; picture-in-picture and independent window transparency |
| EDID | Custom input resolution management for DVI, HDMI and DP |
| Scenes | 10 preset scene templates; built-in clock for scheduled switching |
| Audio | 1 external audio input and 1 output; audio can follow a selected window source or external input |
| Control | LAN, RS232 and USB 2.0 Type-B host control |
| Backup / restore | SD card configuration backup and restore; one-button configuration recovery described in the feature list |
| Light sensor | SENSOR port for an external brightness probe and automatic brightness adjustment |
| 3D qualification | Active shutter/frame-sequential 3D is listed, but the 3D transmitter interface is marked reserved and requiring customization. |
| Display controls | Key lock, image freeze and one-key black screen |
| Power | 100–240 VAC, 50/60 Hz; rated 36 W |
| Environment | −20 to 70°C; 10–80% RH, non-condensing |
| Dimensions / net weight | 482.2 × 360 × 88.9 mm (L × W × H); 5.05 kg |

Frequently asked questions
Is MVB20E rated for 13 million pixels?
The PDF overview and basic parameter table say 13 million, but its output table says 10.2 million and its feature list contains “1300 Million Pixels.” Because the document is inconsistent, confirm the maximum load for the exact hardware and firmware revision before specifying a screen.
Does a very tall screen change the loading capacity?
The basic parameter section says capacity reduces above a height of 8192 pixels and gives 11.98 million as a minimum. This statement conflicts with the separate 10.2-million output table, so a tall layout needs a revision-specific capacity check.
Can HDMI 2.0 and DP operate simultaneously?
No. The specification describes HDMI3 and DP as alternative UHD inputs, with only one used at a time. The separate HDMI 1.3 and DVI inputs have their own format limits.
How many layers and saved scenes are available?
The document lists up to five simultaneous picture layers with independent transparency and ten scene templates. A built-in clock supports scheduled scene switching.
Are 3D and automatic brightness available without extra hardware?
The SENSOR port connects to an external light sensor. The 3D transmitter port is identified as reserved and requiring customization. Confirm the required sensor, transmitter and enabled configuration; the PDF does not establish that these accessories are included.
