I currently use my old laptop that is connected to my PC via ethernet cable (not sure what type) as a second monitor; however, it seems that the screen is limited to 30 FPS while my laptop's screen supports 60 Hz. As far as my knowledge goes, spacedesk is hardcoded to run at 60 FPS. So what might be the problem?
