YEYIAN is a company you might not have heard of. Based in San Diego, they are mainly known for their pre-built gaming PCs, but recently they have ventured into the monitor space and today we are taking a look at one of their latest models, the Sigurd 4000. This 34-inch ultra-wide display makes use of a VA panel and offers a 3440 x 1440 resolution, 165 Hz refresh rate, a 1500R curve, and support for both AMD FreeSync and NVIDIA G-SYNC technologies. Whats better is that YEYIAN is offering this monitor for only $369.99, which makes it quite affordable given its specifications.
