problem capturing video of ultrasound scan

[ritcH]

I'm trying to figure out how to create a video of ultrasound procedures, for teaching purposes. I'm trying to use an avermedia LGP Lite gl310 to take hdmi or dvi > hdmi from the ultrasound machines then stream the video to OBS on my laptop.

If I connect an hdmi lead from the ultrasound to a monitor the image is stable and a perfect mirror of what is on the machine's display.

However on two separate ultrasound machines one with an hdmi port and one with a dvi port although both made by sonosite with similar software I am getting a screen glitching / flickering issue. I attach a video to demonstrate the problem.

I don't suppose anyone knows what's wrong or how to begin troubleshooting this?

I haven't asked the IT department for help, the ultrasound could potentially connect to PACS although, I don't work in radiology so these machines aren't connected like they might be for that department. The machines themselves can create clips but are limited to 30s in duration whereas the procedures I'm trying to record may last several minutes. It's frustrating to be able to capture an image, just a wobbly image I'm just wondering if it's some obvious setup issue.
