Question / Help HDMI video preview freezes in OBS Studio

New Member
Hope someone can help me. I've used OBS Classic for almost successful two years and now I am trying to change to OBS Studio on Windows10 to stay up to date with your support.

Problem
:
After I installed Studio, I would see my video feed from my camcorder for a few seconds, and then the preview freezes. I would test this immediately in Classic and find my HDMI port is not receiving any video signal at all. So I would restart my computer and test my video feed in Classic to see it back to normal. Then I exit Classic and launch Studio and find my video would freeze again. As you don't support Classic any longer, how can I change to Studio if I can't maintain this video feed? Did I miss a step or has there been a solution to this problem?

PC:
HP Elitebook 8540w (laptop);
Intel Core i7 CPU M620 @ 2.67GHz;
64-bit Windows 10 Pro

GPU:
NVIDIA Quadro FX 880M

Source Video:
Canon Vixia HF R52 via HDMI plugged into HP ExpressCard

All drivers appear to be up to date and working well in Classic. But, when I run OBS Studio, I get this:
