Usb screen output or anti flicker settings

Hi,

I was in the idea to test filming a tutorial with the Hapax but instead of filming the screen I was wondering if it’s not possible to have some kind of “screen output” from usb ? Generating what is view on screen but with best quality ? As actually I need a good camera to film it that I can’t use for something else I would better have that kind of rendering. It makes it also harder with usb hubs and later mounting to use a high resolution

Otherwise for people who did it what’s the best settings for filming the screens ? Contrast and anti flicker ? The parameters are not explained in manual.

Some settings seems better for camera but dark for humans eyes.
Or do you know a quite cheap usb camera dedicated to film screens ?

It would be nice to get data out of that USB port so we could make an independent display. If Squarp enabled even just an API I could code a separate UI to run separately and monitor Hapax independently.
