Newegg offers the Changhong 42" 4K 2160p LED-Backlit LCD UHD Television, model no. UD42YC5500UA, for $329.99. Coupon code "MEMDAY30" cuts it to $299.99. With free shipping, that's $700 off and the lowest total price we could find, although we saw it for $3 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, and four HDMI inputs.
