Newegg offers the Changhong 42" 4K 2160p LED-Backlit LCD HDTV, model no. UD42YC5500UA, for $399.99. Apply coupon code "EMCWHPE67" to cut it to $379.99. With $9.99 for shipping, that's $510 off and the lowest total price we could find, although we saw it for $15 less last week. (It's still a very low price for a 42" 4K HDTV.) It features a 3840x2160 native resolution (four times that of 1080p TVs), LED backlight, USB port, and four HDMI inputs. Deal ends December 11.
