MVB4S Pro processing and LED display control
The Mooncell MVB4S Pro is listed as a 2-in-1 LED video processor with four network outputs, front-panel screen setup and dual-screen display using HDMI and DVI sources. Its picture-in-picture, overlay and scheduled switching functions support presentations that need more than a single full-screen source.
Model note: the original product page names MVB4S Pro, while the retained specification PDF names MVB4S. The Pro listing gives 2.6 million pixels and one HDMI input; the PDF gives 2.5 million pixels and lists two HDMI inputs. The table preserves the Pro listing’s claims and identifies the conflict. Electrical ratings and dimensions from the non-Pro PDF have not been assigned to this product.

Frequently asked questions
Is MVB4S Pro the same model as MVB4S?
The product listing is for MVB4S Pro, but its existing PDF is titled MVB4S. The sources differ in loading capacity and interface details, so they should not be treated as identical hardware. Confirm the model label and revision when ordering or replacing a unit.
Does MVB4S Pro support 2.6 million pixels?
The original Pro listing states 2.6 million pixels in total and 650,000 per network output. The linked non-Pro MVB4S PDF states 2.5 million in total. This discrepancy is unresolved; confirm the applicable Pro limit before finalizing the screen layout.
Can HDMI and DVI be displayed together?
The original MVB4S Pro listing specifies simultaneous HDMI and DVI display, with picture-in-picture or picture-outside-picture and adjustable image size.
Can the screen be configured without a computer?
The listing describes front-panel setup using the knob and buttons, plus a guided setup mode for quick screen connection. It also lists custom EDID management and point-to-point image scaling.
What should I check before buying an MVB4S Pro replacement?
Match the Pro model label, hardware revision, video connectors, receiving-card setup and required pixel load. Use the linked PDF as MVB4S reference material only until its applicability to the Pro unit has been confirmed.
