Given FreeSync and GSync it is now possible that graphics card and monitor work together to support variable frame rates and control when a monitor refreshes.
My question is if with a fixed framerate monitor there is any way to do something similar in a very limited way. I would like to cause a slight delay of the vertical retrace of a monitor (via HDMI / DVI) to come in sync with an external image source.
Is this possible based on TMDS based video connections? Is this something any graphics cards exposes?
