Best Buy offers the Lenovo L24q-20 23.8" 1440p WQHD IPS LED-Backlit LCD Monitor for $159.99 with free shipping. (Amazon has it for the same.) That's the lowest price we could find by $19, although we saw it for $10 less a month ago. It features a native resolution of 2560x1440 (1440p), 4ms response time, and DisplayPort and HDMI inputs.
