If you're on the market for an affordable 4K smart TV, you should check out Walmart's early Black Friday sale, as the retailer has a great deal on a very large TCL 4K TV. The TCL 75-Inch Class S4 4K Roku TV is discounted to only $378 (was $498) until November 17.

The TV runs on the Roku TV OS, which supports all the popular streaming apps like Netflix, SlingTV, YouTube, and more, and there's a built-in OTA TV tuner you can use to access over 250 free channels. Oh, and you can use the Roku smartphone app as a second remote. While this makes it a great pick for streaming video or watching Blu-rays, it also features an Auto Game Mode that dynamically changes the picture settings for the lowest possible input latency when using a console, making it a solid choice for gaming, too.
