Complete Video Wall
MVB4S Pro in a Typical LED Display Control Rack — 4× Gigabit Ethernet to Receiving Cards
Video signal enters the MVB4S Pro through HDMI, DVI, or VGA. The built-in 12-bit processing chip scales, de-interlaces, and color-corrects the image. The processor routes pixel data through 4 Gigabit Ethernet ports directly to LED receiving cards on each cabinet, which drive the LED modules. The result: a seamless, synchronized LED video wall powered entirely through one MVB4S Pro — powered by one device, configured in minutes.

Troubleshooting — Common Issues & Solutions
No Signal on LED Display
Check: Input source LED on front panel — if flashing, source is selected but has no signal. Verify cable connection. Confirm source device is outputting a supported resolution (max 1920×1200 for DVI, 1920×1080 for HDMI). Solution: Connect a known-working source. Check EDID settings.
Image Flickering or Tearing
Check: Ethernet port indicator — solid yellow + flashing green = normal. Both solid = no receiving card detected. Solution: Re-seat Ethernet cables. Verify receiving card firmware matches. Check that output resolution does not exceed 2.6M pixels or width 3840.
Color Distortion or Wrong Colors
Check: Color depth setting. VGA sources may need manual RGB adjustment. Solution: Verify HDMI/DVI cable supports required color depth. For VGA, run Auto-adjust. Check EDID color format matches source output (RGB vs YCbCr).
Screen Partially Not Displaying
Check: Ethernet port assignment in output settings. Network cable to affected section. Solution: Verify each of 4 Ethernet ports is properly mapped in AutoLED software. Check receiving card status LEDs. Confirm total pixel load across ports does not exceed 2.6M.
