The best monitor that's available for purchase is the Alienware one. 1440P G-Sync 34 inch IPS display with the highest native refresh rate (100hz, overclockable to 120hz). Best OSD and has a much better build quality than the Acer X34 or the Asus IPS. It also has a much better reputation for less back light bleed. You can find a pretty good deal on it buying directly from Dell.
