J&R offers the factory-refurbished Sharp AQUOS Quattron 40″ 120Hz 1080p LED-Backlit Widescreen LCD HD Television, model no. LC-40LE820UN, for $529 with free shipping. It’s $120 under our mention of a new unit from last summer and the lowest total price we’ve seen for any Quattron LCD TV. (It’s currently $1,250 less than the best we could find for a new unit.) This LCD TV uses Quattron quad-pixel technology, which adds yellow pixels to the standard RGB. Other features include a native resolution of 1920×1080 (1080p), 120Hz refresh rate, edge-lit LED backlight, 5,000,000:1 dynamic contrast ratio, 450 cd/m² brightness, 4 ms response time, Ethernet connectivity with AQUOS Net service (Netflix streaming and more), four HDMI inputs, and VGA, component, and other video inputs. A 90-day Sharp warranty applies.
