Luckily, there's a smart 4K TV that's swooping in with a surprising sale to save the day.

As of June 6, the onn. 50-inch 4K Roku smart TV is on sale for $198 at Walmart, down from $238. The lowest price this particular onn. model previously had at other retailers was $244.06 in June of last year. So we suggest you move fast to elevate your next TV marathon, because we don't think this deal will last long.

Spec-wise, this smart TV boasts a 50-inch LED screen, 4K resolution (which translates to 3840 × 2160 pixels and a crystal-clear display), and thousands of available free or paid channels through Roku. Plus it has a 60hz refresh rate, which is a fancy way of saying the screen can refresh itself 60 times per second, meaning you're going to get smooth versus choppy motion when gaming or watching the US Open. This onn. smart TV is also smart home-compatible, so you can let Google Home, Apple Home, or Alexa know verbally when to skip an episode or turn on subtitles.

If you're not interested in large screens and want to go the minimalistic route, there's an even cheaper option available for you at Walmart: an onn. Class HD Roku smart TV in a 24-inch size, for only $88.
