The first 4K Roku TVs hit Best Buy for $400 and up

The new LED Insignia models come in 43-, 50- and 55-inch sizes.

Roku TVs afford you all the same features and apps the dinky set-top boxes do without cluttering up your entertainment center. Last year, Roku caught up with the times by launching the Ultra HD-ready Roku 4, also setting the stage for its TV partners to build 4K sets with the platform baked-in. Chinese manufacturer TCL was expected to be the first to market, but it's been beaten to the punch by Best Buy today with the launch of the first 4K Roku TVs under the retailer's Insignia brand.

Like the Roku 4, the new LED Insignia line-up all support dual-band 802.11ac WiFi, giving you the wireless speeds you need to enjoy the 4K content and channels available on Roku's platform. They arrive in 43-, 50- and 55-inch flavors at a cost of $400, $500 and $650, respectively. As you've probably guessed, they're available exclusively at Best Buy, which is selling them online from today and in-store from early next month.
