hd60 screen tearing, I thinnk sooo, idk!!!

Hi, I'm trying to set up a dual PC streaming setup with my Elgato HD60 (I know it's old, but I got it for free), but I experience screen tearing during my stream. I'll attach my clip.

Specs :
PC main : 2070 super 8gb - i5 12600kf my monitor 144hz
PC stream: nvidia 1050 4gb - i5 8700H - 60hhz (its a laptop)
I think it's because my monitor has a higher refresh rate than what the Elgato HD60 can handle. If anyone could suggest something to fix this, I would appreciate it. Thank you!
