Pros: 2K resolution and best I/O available at the price. Has in-built speaker. Agronomic design and good appearance. Resolution is crisp and clear, which was lacking for my previous 27" HD (1080p) monitor.
Cons (wearing a critique hat): inbuilt monitor speaker is rather weak so I am using dedicated speakers. Nightmare to calibrate picture quality and found monitor is too bright, however this was sorted using NVIDIA card calibration capability. there are other programmes online or windows calibration feature which does similar job. the biggest take though is menu control panel, not the best in class for this monitor.
Overall, one happy customer, so far (using it more than a month now!)
