Like other G-Sync displays, both of these match your GPU's refresh rate with the monitor's as a way of eliminating the sort of bumpiness you'd normally get if you extended your gameplay onto a bigger screen. The in-person demo we got today reminded us how effective the technology is, especially in side-by-side comparisons with older monitors. But don't take our word for it -- the demo video embedded below does a better job capturing the benefits than any hands-on walk-through we could put together. Even if you're already aware of how the technology works, you might want to check it out; it's the clearest demonstration of the technology we've seen yet. As for the question of "when can I buy these?", well, we're not actually sure yet. No word on when either of these will arrive or how much they'll cost, but the Acer model, at least, is slated to ship in Q2, which means it should go on sale very soon.
