"DeckLink Mini Monitor" as a graphics card, extended display

I want to add 2 SDI graphic outputs on a Windows 10 system that are set desktop extensions.

Can I put 2 of the "DeckLink Mini Monitor" cards in a system and extend the desktop to these 2 windows to put full screen PowerPoint display on the SDI signal where the screens are 1280 X 960 (4:3) resolution?

Thanks,
Dave

Sorry, NO.

As far as I know, BMD does not have a Windows driver that allows it to be either a primary nor secondary
display.

The price of a Dual DVI or HDMI video card would be an easier solution.

Get a video card with multiple outputs.. And 2 HDMI to SDI micro converters to go to SDI.

You can not extend your screen to a BMD card in windows / mac.. Only software that is able to output video to the BMD cards will do that.
