Amazon offers the TCL 50" 4K2K 2160p LED LCD HD Television, model no. LE50UHDE5691, for $749 with free shipping. That's tied with our Black Friday mention (which lasted less than two hours) and the lowest total price we could find by $32. It's also among the cheapest 4K TVs we've seen. It features a 3840x2160 resolution — four times that of 1080p TVs. It also has a 120Hz refresh rate, LED backlight, and three HDMI ports. Note: No one is currently broadcasting or releasing content in this resolution ... but one day they will and you'll be ready!
