Walmart is currently discounting RCA's 50-inch 4K HDR TV with Roku built-in, bringing the price down to $299. That is good for $400 off of its regular price, and definitely worth picking up if you are looking for a new TV to add to your home. This does support both 4K and HDR technologies, so it's a really good TV if you're looking for a good picture quality.
This TV from RCA does measure in at about 50-inches, which is going to make it great for a living room or a den. Additionally, it is a 4K HDR TV, so you're going to get a really great looking picture out of this one. Unfortunately, there is no Dolby Atmos or Dolby Vision support here, but that's not a huge surprise, given the fact that this is a $300 50-inch TV. The audio quality here is pretty decent, though you will likely want to pick up a soundbar to go with this TV. Lastly, this TV has Roku built-in. So that means you won't need to add a Roku stick to this TV, and you get all of your favorite apps and games included. That includes YouTube, Google Play Movies & TV, Netflix, Amazon Prime Video and much more.
