Communication between the graphics card and the monitor

Hi everyone,

I would like to ask about two things related to communication between the graphics card and the monitor (display) in the context of temporal dithering.

1) If the graphic card uses temporal dithering, does the monitor have to always use such instructions?

2) When buying a monitor that is so-called true 8bit monitor (not 6bit+frc, not 8bit+frc) will eliminate or minimize the degree of temporal dithering imposed by the graphics card?

Thanks for the help
