Doses DeckLink Mini 4K Monitor support 12bit RGB 1080p 24?

Hi,

I have a "DeckLink Mini Monitor 4K" card.

And I want to use it output 12Bit RGB 444 1080p 24fps to a X300 monitor.

I modified the Sample "TestPattern" in the BM release SDK.

But the result shows not correct.

My question is whether "DeckLink Mini Monitor 4K" support 12Bit RGB 444 output?

Even if I set the output to 10Bit RGB444, then I set the X300 input format is RGB10bit 444, the display is black, but I set the X300 input format to YCbCr422 10 bit, the display is correct.
The 3G-SDI can't support RGB444?

I read the spec of "DeckLink Mini 4K Monitor" carefully.

https://www.blackmagicdesign.com/products/decklink/techspecs/W-DLK-32

In the "Connection" it said that
SDI Video Outputs
1 x 10 bit SD/HD/Ultra HD switchable.

But in the "Video Standards" it said that
SDI Color Precision
8, 10, 12-bit RGB 4:4:4 in all modes up to 1080p60, and 8, 10-bit YUV 4:2:2 in all modes.

I am confused. Whether this card support 12 bit?
