I have had this monitor for about two months now without any problems what so ever *knock on wood* the 120hz refresh rate is worth the money alone for this monitor, Any game i play weather it being a new game or a older game they all run great with vsync. I have actually never been able to use vsync untill this monitor. The 1920x1080 resolution and 120hz refresh rate make all my games look very crisp and smooth. This monitor has different modes, such as Graphics, Movie, User, Standard, and ECO. Now for the best part of this monitor the Steroscopic 3D! This monitor looks very awesome in 3D, I use the Nvidia 3D Vision setup i could not ask for a better 3D viewing experience weather it's a video game or a 3D Bluray movie it looks amazing. I also thought about buying two more of these monitors for the Nvidia surround setup, but this monitor is plenty big enough for me the 23.6" is enough to keep yours eyes busy. Thank you Amazon for the outstanding service, And thank you Acer for such a great product.
