Panasonic offers the Panasonic AX800 57.5" 2160p 4K Ultra HD LCD Television, model no. TC-58AX800U, for $1,999.99 with free shipping. (Best Buy and Amazon offer it for the same price.) That's tied with last month's mention (although that one included a Blu-ray player), $1,300 off list, and the lowest total price we could find. It features a 3840x2160 native resolution (four times that of 1080p TVs), LED backlight, WiFi, SD card slot, USB 3.0, DisplayPort, and four HDMI ports.

Note: It's not guaranteed for delivery by Christmas.
