Little more card can change resolution from higher to lower but not FPS or interpolation to progressive mode.

If a manual is present please read these thoroughly to ensure correct operation/set up of the product. Are you implying that my 4k video source is somehow listening to what I am doing, and changes what it sends when it realizes I am running OBS? Any camera with unencrypted HDMI output and a supported resolution and frame rate will appear like a webcam in various applications.A powerful video mixer engineered for multicam production, Cam Link Pro equips you to capture four video inputs with ultimate ease and flexibility. What I want is for only the top-left 1920x1080 pixels of the 4k source to take up the entire canvas. This amount includes seller specified domestic postage charges as well as applicable international postage, dispatch, and other fees. I can use the Elgato capture software, and get a full 4k30 signal, and the windows camera app shows a full 4k30 (and yes, I can specify 30hz as the output for my MBP). Finally, as shown in the attached image of the Camlink Pro Device Properties in my first post, its video is "3840x2160p" with a refresh rate of "30fps" This is why I believe it is something in OBS.

Picture in Picture, Side by Side, Triple, or Quad — choose your Multiview layout in Elgato 4K Capture Utility, and switch layouts on the fly with Elgato Stream Deck. Picture in Picture, Side by Side, Triple, or Quad — choose your layout and set HDMI-1 / Multiview as the camera input in apps such as Zoom, Slack, and Microsoft Teams. The project is set for 30FPS and the Cam Link Pro can only do 4k at 30FPS, so it should be able to get a 30FPS 4k mode from the camera as other software do.

A powerful video mixer engineered for multicam production, Elgato Cam Link Pro equips you to capture four HDMI signals from cameras, computers, laptops, tablets and more. jpg file attached to my first message), and somehow it seems to be getting set to 1080p elsewhere by OSS. To fix this, go into Resolution/FPS Type choose Custom choose 3840x2160 and change the Video Format to one that comes in at 4k resolution (I tested mine until one came through and filled the screen). I feel like camlink pro has enough inputs for video/audio but is it any good for capturing gaming etc, I also noticed it tops out at 4k30. Then when I rescale it all back down to 1080p, I am right back where I am now, with my 4k source scaled to take up the entire base resolution.

In OBS even if I have canvas and output set to 3840x2160, and add the source capture video configuration at 3840x2160, OBS seems to see it as a 1920x1080 device. I wonder if the problem is that OBS is trying to connect to the source at a higher FPS then it should be. To handle the full 3840x2160 you should set your OBS Base resolution to that, and the scaled output size to 1080p then. The upper left side is Elgato capture utility, and I've conveniently circled where it states that it is RECEIVING A 4k30 signal.The lesser usb3-based CamLink 4k does work at 4k -- though obviously the 4-hdmi pcie card would be preferable. Grabber (like Cam Link Pro) is passive device, your source must correct introduce list of resolution.
