Newegg offers the refurbished AOC 27" Ultra-Slim IPS LED Monitor, model no. I2757FH-B, for $129 with free shipping. That's $151 under the lowest total price we could find for a new model. It features a native resolution of 1920x1080 (1080p), D-Sub, HDMI, LED backlight, and ultra-narrow bezel for a borderless appearance.

A 90-day warranty applies, but it's unclear who backs it.
