Why Small Screens Deserve a Real 2-in-1 Processor, Not Just a Sending Box
A storefront or signage wall technically runs off a bare sending unit — until the client wants two sources, a logo overlay or a second zone. Then the chain grows a processor, a second enclosure and a second configuration, and the “cheap” setup quietly doubled. The MVB4S Pro 2-in-1 LED video processor gives small walls a real image-processing engine plus a 4-port sending card in one 480 mm-wide unit from the start.
Mooncell built it around a top-tier image processing chip with internal 12-bit digital processing and adaptive processing for interlaced motion video, so even ordinary PAL/NTSC feeds reach the screen with clean detail and saturated color — the same engine family as the bigger processors, scaled to the screens that actually sell in volume.
Right-Sized Drive
4 gigabit ports carry up to 2.6M pixels at 3,840 wide or 1,920 tall — every pixel of a typical small wall.
Quick Setup
Quick screen linking configures the screen connection from the front panel — no computer software required on site.
12-Bit Engine
Internal 12-bit processing plus adaptive de-interlacing for clean, colorful images from HD and legacy sources.
Dual Window
HDMI and DVI display simultaneously with adjustable picture-in-picture or side-by-side windows.
MVB4S Pro Inputs: Twin HDMI, DVI with Loop-Out and Analog VGA
Small-wall source mixes are full of legacy: old presentation laptops, VGA signage players, computers whose DVI output also needs to feed a nearby monitor. The MVB4S Pro covers them with HDMI, DVI — including DVI-LOOP loop-through — and analog VGA, each with custom resolution and custom input EDID management.
| Input | QTY | Capability |
|---|---|---|
| HDMI 1.3 | 2 | Up to 1920×1080@60Hz each (one HDMI2 interface built-in); HDCP 1.4; custom resolution to 2048×1080 or 1080×2048@60Hz. |
| DVI + DVI-LOOP | 1 + 1 | Up to 1920×1200@60Hz; DVI-LOOP passes the source to a second monitor; custom resolution to 3840×640 or 640×3840; no interlaced input. |
| VGA | 1 | Analog RGB, downward compatible; up to 3840×640@60Hz; custom resolution to 3840×640 or 640×3840 — legacy PC input covered. |
| Audio in / Audio out | 1 / 1 | 3.5mm audio input and output with audio/video follow switching. |
The front panel keeps control local: a 160×128 LCD, rotary knob and ESC, dedicated input keys (HDMI1, HDMI2, DVI, VGA), and FUNCTION keys that jump straight to output canvas (GUIDE), PIP swap, LED screen patrol, window scale, scene load and black screen.
2.6M-Pixel Output and Dual-Window PIP / Side-by-Side Display
The MVB4S Pro sends its canvas out over 4 gigabit Ethernet ports to Mooncell receiving cards and multifunction cards, with custom output resolution up to 3,840 wide or 1,920 tall and arbitrary image position. It supports dual display: HDMI and DVI can show two windows at once as picture-in-picture or side-by-side (POP), each size-adjustable — a promo loop beside a live camera, a menu window inside a main visual.
Around that core sit the everyday tools: instant or fade switching between sources, text/image overlay and keying (抠图) for subtitle and logo compositing, per-pixel scaling to the screen resolution, scheduled switching and scheduled brightness, multi-unit cascade splicing, voltage/temperature self-check and quick screen linking.
| Output Parameter | MVB4S Pro Specification |

| Load per port | Max 655,360 px (1280 × 512 per-port load) |
| Max total load | 2.6 million pixels |
| Max width / height | 3,840 px wide / 1,920 px tall; custom output resolution with arbitrary image position |
| Display windows | Dual-window HDMI + DVI simultaneous, adjustable PIP or side-by-side (POP) |
| Supported cards | Mooncell receiving card series and multifunction cards |
Quick Screen Setup, LED Patrol and System Wiring Without the Software
The feature that sells the MVB4S Pro to installers is quick screen setup (快捷点屏): the screen connection is configured from the front panel with simple operations instead of computer software — exactly what Mooncell documents as drastically simplified field commissioning. A press of the LED function key starts a screen patrol that verifies panel status directly.
System wiring stays conventional and serviceable: sources into HDMI/DVI/VGA, audio in and out, and the receiving-card chains on four gigabit ports; the annotated diagram below is the wiring Mooncell publishes for a single-processor small-wall system with audio.
Where the MVB4S Pro LED Video Processor Fits: Small Screens Done Properly
Storefront & Retail Signage: Two Sources, Zero Staff
Retail walls switch between promo loops, live offers and third-party ads. Dual-window HDMI+DVI with PIP lets a shop run two sources at once, scheduled switching rotates them by hour, and scheduled brightness keeps the wall legible day and night — all from a unit small enough to hide behind the screen.
Hotels, Exhibitions & Studios: Presenters and Legacy Laptops
Conference and booth walls live on HDMI laptops — and occasional VGA dinosaurs. The MVB4S Pro’s VGA input and DVI-LOOP swallow the legacy without adapters, while 12-bit scaling keeps projector-class content sharp on fine-pitch panels.
Rental & Multi-Unit Splicing: Consistent Small Rig
Rental houses run fleets of identical small screens. Multi-unit cascade splicing, engineering time lock and cloud platform management let one integrator supervise many deployed units — with the 12-bit engine producing consistent color across the fleet.

MVB4S Pro 2-in-1 LED Video Processor Buying Guide: 5 Checks Before You Order
- Verify the pixel ceiling honestly. Wall width × height must fit under 2.6M px with width ≤ 3,840 and height ≤ 1,920 — including the receiving card’s share. A 3,840×640 banner (2.46M) or 1,080×1,920 poster (2.07M) fits; 4K-content walls do not.
- Count sources and windows. Two simultaneous windows (HDMI + DVI) serve promo-plus-camera setups; if three or more live sources must be visible at once, step up to the MVB12E’s four windows.
- Confirm the source zoo. The MVB4S Pro is the rare modern unit with VGA and DVI-LOOP — great for legacy PCs; but if 4K60 HDMI/DP sources are on the roadmap, pick the MVB12E or above for its HDMI 2.0 / DP inputs.
- Check receiving cards and patrol needs. It drives Mooncell receiving and multifunction cards; the LED patrol key verifies panel status on site — send us your card model to pre-verify the load plan.
- Plan fleet management. If units deploy across many sites, engineering time lock and cloud platform management protect and centralize them — worth confirming your integrator’s workflow supports the cloud console.
Price and Cost Factors
As the entry of the 2-in-1 family, the MVB4S Pro usually costs less than a separate processor + sending card pair — the 2-in-1 economy plus a 44 mm chassis that mounts anywhere. Quantity, pre-terminated 4-port cable sets and commissioning support move the price; ask for a quote covering the complete drive chain so the comparison is apples-to-apples.
MVB4S Pro 2-in-1 LED Video Processor FAQ
Q1 What is the MVB4S Pro 2-in-1 LED video processor?
The MVB4S Pro is Mooncell’s compact 2-in-1 LED video processor: a video processor and a 4-port sending card in one 480 mm-wide, 44 mm-high unit. It scales, layers and switches video, then sends the canvas to Mooncell receiving cards over gigabit Ethernet — built for small and mid-size LED screens that want real processing without a separate sending box.
Q2 How many pixels can the MVB4S Pro drive?
Up to 2.6 million pixels through 4 gigabit Ethernet output ports, with custom output resolution up to 3,840 pixels wide or 1,920 pixels tall and arbitrary image position. Each port carries a maximum of 655,360 pixels in a 1280×512 load format, and the unit supports Mooncell receiving cards and multifunction cards.
Q3 Can I set up the MVB4S Pro screen without a computer?
Yes — this is the MVB4S Pro’s headline feature. Quick screen linking (快捷点屏) configures the screen connection from the front panel with simple operations instead of PC software, which Mooncell documents as drastically simplified field commissioning. Built-in test patterns and the LED patrol key complete the no-laptop install workflow.
Q4 What video inputs does the MVB4S Pro support?
Two HDMI 1.3 inputs (one built-in interface), each up to 1920×1080@60Hz with HDCP 1.4; one DVI input up to 1920×1200@60Hz with a DVI-LOOP output that feeds a second monitor; and one analog VGA input supporting custom formats up to 3840×640@60Hz. All inputs support custom resolution and custom EDID.
Q5 Does the MVB4S Pro support 4K video input?
No. The MVB4S Pro is designed for HD-class and legacy sources: HDMI tops out at 1920×1080@60Hz, DVI at 1920×1200@60Hz, and VGA supports wide custom formats up to 3840×640@60Hz. If 4K60 sources are part of the project, choose the MVB12E or MVB20E-G with their HDMI 2.0 and DP 4K60 inputs.
Q6 How many windows can the MVB4S Pro show at once?
Two. HDMI and DVI can display simultaneously as picture-in-picture or side-by-side (画外画), with both window sizes adjustable — enough for a promo loop beside a live camera or a subtitle overlay on a main feed. Text/image overlay and keying support logo and subtitle compositing on top.
Q7 Can the MVB4S Pro switch content or brightness on a schedule?
Yes. The unit supports timed signal switching and timed brightness adjustment, so content and screen level can rotate by time of day. Instant or fade switching between input channels covers manual transitions, and scene loading is one function key away from the front panel.
Q8 Does the MVB4S Pro support multi-unit cascade splicing?
Yes, the MVB4S Pro spec sheet documents multi-unit cascade splicing, letting several units drive a larger combined canvas. For one-canvas simplicity beyond 2.6M pixels, the MVB12E (7.8M px) and MVB20E-G (13M px) are the usual single-unit choices; our engineers will map the topology either way.
Q9 What are engineering time lock and cloud platform management?
Engineering time lock is an integrator/rental protection tool that limits unit operation on a time basis — standard practice for preventing unpaid long-term use of rented equipment. Cloud platform management lets authorized integrators monitor and manage deployed MVB4S Pro units remotely over the network.
Q10 How is the MVB4S Pro controlled and monitored on site?
From the front panel: 160×128 LCD, rotary knob and ESC for menus, dedicated HDMI1/HDMI2/DVI/VGA source keys, and FUNCTION keys for output canvas, PIP swap, LED screen patrol, window scale, scene load and black screen. LAN, RS232 and USB-B (AutoLED) provide PC and control-room integration.
Q11 Does the MVB4S Pro support audio?
Yes. It provides 3.5mm audio input and output with audio/video follow switching, so the audio path tracks whichever video source is selected. The output can drive an amplifier or venue audio system alongside the LED screen; volume is managed through the unit menu.
Q12 How much does the MVB4S Pro cost and what is in the box?
Pricing depends on order quantity and support scope — contact our team for a factory-direct quote. The box includes the MVB4S Pro, power cord, USB 2.0 cable, HDMI cable, DVI cable and certificate of conformity, packed 3 units per carton; net weight is 2.8 kg.
