Newegg offers the refurbished HP 22" 1080p LCD Monitor, model no. ZR22W, for $84.99 with free shipping. That's the lowest total price we could find for a refurbished unit by $15. It features a 1920x1080 (1080p) native resolution, 1,000:1 contrast ratio, and DVI and VGA inputs.
A 90-day warranty applies, although it's unclear who provides it.
