As Amazon prepares for a Prime Day marathon, Best Buy is holding a flash sale where you can shop now.

One of the best deals in Best Buy's sale is a 55-inch OLED 4K TV from Vizio for $999.99. This is $300 off and is the cheapest OLED TV we have seen in 2021. This is also the best TV sale of the year. (It could also be the best Prime Day TV sale this month.)

The Vizio OLED55-H1 is the company's first OLED TV. At 44 mm thin, this TV features Vizio's new ProGaming Engine. Essentially, this means that 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.

In our review of the Vizio OLED TV, we found this 4K TV to be more than its price tag; the noticeable difference in contrast and black levels between Vizio's OLED TV and its top-of-the-line P-Series Quantum X impressed us; the P- Series X offers bright, vibrant colors, while Vizio's OLEDs have deeper black levels, giving the 4K picture a sharpness that even top-of-the-line LCDs cannot match. We also liked the wide viewing angles. Even from extreme off-angle angles, only slight color distortion is visible (and barely noticeable).

If your budget is limited, the 55-inch model is a nice price at $999. If you can spend a little more, the 65-inch model is the cheapest ever at $1,499.
