So first things first, this is NOT a G-sync monitor. It is G-Sync compatible. Best Buys web site list it as a G-Sync monitor but that is incorrect, a quick Google search will confirm this. Anyway, that aside this monitor is a decent entry level gaming monitor. My 1060 had no issue enabling G-sync for the monitor and setting the 165Hz refresh rate. You'll need to use a Display Port cable, one comes with the monitor, to do get they higher refresh rates. 144 or 165. The colors are good but you can easily find monitors/panels with better colors. That is not the strength of this monitor, it is the refresh rate and for such a low price! This is a common give and take with TN panels and not really a knock against the monitor in my opinion. My other monitors are Dell S2716DG's which are also TN panels and the colors do look better but they also cost about 200 more than this monitor does and cap out at a 144Hz refresh rate. My only real issue with this monitor is that it did not seem to work well with my other 2 monitors. I got this monitor for it's 1080P resolution and the fact that it could match my other monitors at 144Hz or even go a little past at 165Hz. I wanted to use this monitor for my FPS games. The problem was that when ever I played a game on this monitor my other 2 monitors would start to shudder/skip. Even when I played a game on one of my other monitors the shudder/skipping would start happening with this monitor. If I played any games with only this monitor connected it performed great and as expected but as soon as I added both or even just 1 of my other monitors the problem came back. I think the problem was the fact that this monitor is only G-Sync compatible while my other 2 monitors are actual G-Sync monitors but who really knows. I did a lot more troubleshooting but could not get the issue resolved. TL;DR - This is a great entry level gaming monitor, especially for the price. If you already have other true G-Sync monitors you may have issues using then at the same time on the same PC.
