DBS-HVT11 / HVT2011 LED Sending Card
The DBStar DBS-HVT11 sends display data in a DBStar LED control system. The listed screen types include single-color, dual-color and full-color displays, with real-pixel and virtual-pixel configurations.
Control-System Specifications
The original specification includes both sending-card and receiving-system figures. Receiving-card load, RGB groups, grayscale, refresh rate and correction limits depend on the receiving card and LED driver; they are not separate output specifications for this sending card. Fiber distances apply to the appropriate optical transmission configuration.

Replacement and Compatibility
For an existing HVT2011 installation, record the receiving-card model, LED driver, screen pixel layout and connection type before ordering a replacement. A matching pixel count alone does not establish compatibility with another controller.
Frequently Asked Questions
Are DBS-HVT11 and HVT2011 names used for this product?
Yes. This product is listed as DBS-HVT11 (HVT2011). Match the actual board label and connection layout when replacing an existing card.
What is the listed sending-card pixel capacity?
The table specifies 2048 × 640 pixels using dual ports. Keep this separate from the receiving-card load figures in the same table.
Is the listed refresh rate guaranteed with every LED driver?
No. The table distinguishes typical and maximum values and gives MBI5042 as an example for the higher refresh-rate figure. Check the receiving-card and driver combination.
How do I choose a compatible replacement?
Compare the exact sending and receiving models, driver-chip support, connectors, firmware requirements and screen layout. Do not assume two cards are interchangeable because their maximum pixel counts match.
