I have been trying to use my monitor at my desk play and capture Nintendo Switch gameplay, but my monitor will not detect any signal coming from the capture card. Anything feeding directly into the monitor works just fine, but nothing works through the capture card HDMI passthrough. The HDMI passthrough works on every other screen I have tested it with.

I have contacted the support team for the capture card and they claim that the capture card does not do any signal processing for the HDMI passthrough.

Is there something I'm missing? I am at a loss as to what could be causing the issue.
