Micro Center offers the Acer 27" S277HK 4K Ultra HD IPS LED-Backlit LCD Monitor for $329.99. Opt for in-store pickup to dodge the $17.10 shipping fee. That's tied with last week's mention and the lowest price we could find by $110. It features a 3840x2160 (4K) native resolution, LED backlight, built-in speakers, and HDMI, DVI, and DisplayPort inputs.
