The Hisense R6 50-inch 4K Roku TV has all the essentials such as Dolby Vision HDR and HDR10, along with Roku TV built-in so it’s easy to find something to watch without needing to connect a separate streaming device. There’s even a gaming mode if you want to play games on it.

Walmart has a deal on the 55-inch Samsung QLED 4K TV that will cost you less than $300 — but only during its "Black Friday Deals" sale. Here's when to grab this big markdown.
