The legacy description contains conflicting 10-bit and 16-bit video-source claims. Source bit-depth compatibility should be confirmed for the supplied firmware; it is separate from the stated 16-bit brightness calibration.
Frequently Asked Questions
Can the HRV09S receive images without a dedicated sending card?
The listing supports image sending from a PC with a 1000M/Gigabit network card. Confirm the required DBStar software and system configuration before using this mode.
What supply voltage is listed?
The working voltage range is 2.5–12 V DC.
Does it support brightness and chromatic calibration?
Yes. It supports 16-bit brightness calibration and chromatic calibration.
Is the maximum refresh rate available in every configuration?
No. Refresh rate depends on the LED driver and display setup. The original table gives MBI5042 as an example for its higher refresh-rate figure.
Where can I check the current price and availability?
The current product price and available stock are shown above the description. Check them when placing your order.
