Walmart offers the UpStar 29" LED-Backlit LCD Monitor, model no. M29A1, for $199 with free shipping. That's $40 under our mention from a month ago, the best we could find by $130, and a very low price for a 29" 21:9 display. It features a 2560x1080 native resolution, 21:9 aspect ratio, 5ms response time, and HDMI, DVI, and VGA inputs.
Note that although Walmart lists the aspect ratio as 16:9, according to the manufacturer, it's 21:9.
