We really did like the PG279Q and we've now found our new reference gaming screen! The gaming performance was excellent, and second to none at the moment. Very fast response times for an IPS panel, 144Hz native refresh rate support, no lag, NVIDIA G-sync capability, ULMB blur reduction mode and a few nice gaming extras all add up to an excellent gaming offering. The overclockable refresh rate is little more than a marketing gimmick in our opinion, only because you already have a very high native refresh rate anyway and the bump isn't significant, let alone easy to power from your system. Had it been a boost from 60Hz to 165Hz we would have been more impressed at the change no doubt, but here it wasn't really necessary. On top of the gaming performance you have a very good default setup, strong contrast ratio, flicker free backlight and a quality build and design. The price point is of course high, but you are paying for a quality product here with some top notch performance.
