Yes, I have been using a Samsung Odyssey, 27 inch, 2560x1440, 1 ms, 240 Hz curved gaming monitor for about two months now. The curvature is more extended compared to the more "normal" curved monitors available. I have not seen any screen distoration or distortation of any kind in Trainz surveyor, drive, or in any game at all so far.
It only took a couple of hours in game initially to get used to the curve having come from a flat screen, but it was a big wow for picture etc, plus a lot more 'immersive'. The peripheral vision is more focused in game and not so much outside the monitor fame. The only thing that did stand out a bit, which took a couple of days to get used to, was when having a web page up, the curve was more noticible with the straightness of the web page. But now I am used to it and it is fine. The higher refresh rate is very noticible for the eyes and they do not get tired or dry now. I highly recommend a monitor with a refresh rate of at least 144 and up.
