The most popular Black Friday TV sale is back in stock.

For a limited time, Best Buy is offering the new Vizio 55" 4K OLED TV for $899. That's a $400 discount, making it the cheapest OLED TV we've ever seen. In fact, it's one of the best Black Friday deals ever. Want a bigger screen? Best Buy has a Vizio 65-inch OLED 4K TV for $1,499.99. That's a $500 discount and the lowest price ever.

The Vizio OLED65-H1 is the company's first OLED TV. At 44 mm thin, this TV features Vizio's new ProGaming Engine. Basically, it automatically adjusts the panel's refresh rate to match the source device. It also supports AMD FreeSync and 4K gaming at up to 120 Hz.

We experienced the 65-inch Vizio OLED TV in person and were impressed by the noticeable difference in contrast and black levels between Vizio's OLED TVs and the top-of-the-line P-Series Quantum X.

The Vizio OLED TVs are also available in a variety of colors.
