Personally the resolution would be too low for me on that one. I tried a 34" LG @ 3440x1440 and while it was a very nice monitor, after working with retina-level screens for years, the resolution was just too low. It was difficult to discern in my work whether what I was seeing was the low resolution of the screen or a flaw in the image/asset.
I switched to the LG-34WK95U-W and it is much better. I love the widescreen format, and this is afaik, the only wide-screen display in this price range with 5k-ish resolution.
