Consider changing the desktop size and placement in the Nvidia Control Panel. Pick the appropriate monitor, make sure to enable "Override the scaling mode set by games and programs," and verify the refresh rate is correct. This might help, though it isn't guaranteed to fix the issue.
Your Mainscreen runs at 144 Hertz and your second one at 60 Hertz. Could this be related to a hardware problem, such as a faulty GTX 970? Even though the clock readings seem correct, many users reported similar issues on forums, with over 90% mentioning a GTX 970.
I haven't seen a Gsync display myself, so I'm not sure what to say about it.
I'm skeptical about that. The main goal of g-sync is to stop screen tearing, which I think doesn't really impact smoothness. Maybe the opposite is true: Without vertical sync, extra frames might show up, though tearing will still happen. Tearing is less obvious on 144hz screens and isn't a big issue for me.
