The Blackmagic Design DeckLink Mini Monitor is a PCIe slot playback card with both SDI and HDMI outputs for color-correcting or delivering client presentations in more precision on top-resolution HDMI or SDI monitors. You'll be able to send video from your computer to a large HDMI display locally or to an SDI monitor up to 300 ft away.
The card outputs up to 10-bit uncompressed video, and you can output by SDI and HDMI simultaneously or through only one of these. All the outputs are active, so once you plug a cable into them, they'll begin functioning. The card automatically switches between SD and HD, so it'll handle all common video formats.
