Tom's Hardware posted a review on the LG 34WK650 Monitor
A quote from the article:
Since appearing about four years ago, ultra-wide monitors have lived at the premium end of the display market. Whether flat or curved, prices haven’t come down much since we first started seeing this screens. They remain popular with gamers, the top models still cost $1,000 or more.LG 34WK650 Monitor Review
But if you’re willing to accept a non-screen with 2,560x1,080 resolution, then LG has a solution–the 34WK650. At 34 inches, it’s reasonably compact for a 21:9 monitor, but still offers a good deal of space for opening multiple apps, enjoying immersive games, or watching movies. Pixel count is a bit low compared to other 21:9 screens. However, its pixel density is the same as a 27-inch, Full HD 16:9 screen, but with some extra display real estate. The 34WK650 also has plenty of performance credibility with a 75Hz refresh rate, FreeSync and HDR10 support. Most significantly, it sells for under $400.
