Changing Output Resolution Size with DeckLink

PostWed Jan 27, 2021 1:35 pm

I'm trying to change the output from one of my DeckLink Quad outputs to a nonstandard resolution size (1920x768) to match a video wall I'm using. After talking to BlackMagic customer service, they let me know that I'll need some kind of third party software/hardware to do this. Does anyone have any insight or suggestions for changing output resolution?

The final output or shape of an LED wall has nothing to do with the input. Without knowing for sure I'd say the origin of any content would either be centered or top justified within a 1920X1080 raster. Basically you're just letterboxing the output for centered, an top justifying for a 0,0 origin. 1920X768 describes a pixel map, not an available on the wire resolution.

Good Luck
