Decklinkvideosrc unable to show HDMI stream that Blackmagic's Media Express is able to see

I'm working with a BlackMagic Design's DeckLink Quad HDMI Recorder. When using GStreamer's decklinkvideosrc element I've had success grabbing the HDMI stream for multiple devices, but now I've run into a device that when I try to capture it I only receive a blank image. Just by chance I installed BlackMagic's Media Express application today and to my surprise it is able to to see the stream without issue using mode=1080p60, based on Preferences showing "Project Video Format" = "1080p60". Back in the GStreamer pipeline I've tried explicitly setting "mode=1080p60" rather than default to "mode=auto", but that doesn't fix things. Can someone familiar with the innerworkings of decklinkvideosrc provide me with some debugging tips to try and figure out why I can't capture what I know should be doable?
