Your resolution alone will not likely uniquely identify you. The idea is to eliminate many of the data points that make it easy to track you across IPs. Resolution is very common if you're browsing with a maximized window so it's not in the same league as these others that quickly diverge amongst users.
No, not alone. But if you're not masking your IP address, it probably will.
Weirdly, I tried to measure how unique my window.innerWidth/Height was, but panopticlick no longer seems to measure this. It only uses my full screen resolution, which of course is much less unique than canvas dimensions.
