The Acer Predator X34 was a 34" 21:9 aspect G-SYNC display with a 3440 x 1440 resolution.  The newer model sports an updated panel to address the issues some people were having when the X34 hit its top 100Hz refresh rate.  The X34P is able to be overclocked to 120Hz, not only to offer a faster refresh but also to ensure you do not see flickering at 100Hz.  The curve is also more pronounced, however there is no HDR support.  If you are looking for a decent gaming monitor and aren't concerned about the lack of HDR you can read more about it at TechSpot.

"For the past two years the Acer Predator X34 has remained one of the best gaming monitors on the market. I've been so satisfied with it since launch that that I've kept it as my personal monitor for both gaming and video production. But this new monitor from Acer, an upgraded version of the X34, is even better in almost every way."
