This might be the best year yet to buy a 4K TV. The TV you see here is the TCL 55S405. It's a 55 inch 4K HDR Roku TV that has some serious deals going on right now. If you're not familiar with Roku TVs, they are basically smart TVs with Roku built in. They effectively eliminate the need for external streaming box. This TV's 4K resolution looks stunning when streaming from services like YouTube and Netflix, and the HDR does a good job of making colors pop. Sound is fantastic through the built-in stereo speakers. You would expect this TV to cost a lot, but it's on sale on Amazon and Walmart for $369.99. That's a $230 discount from the retail price. I would snag this deal before it's too late.
