We just purchased a Roku TV made by Westinghouse last weekend, so my spouse & I are quite new to Roku. My husband's favorite news channel is Fox News, which is available on Sling Blue; however, Sling TV's help page says that it supports Roku TVs made by Hisense and TCL, but does not mention Roku TVs made by Westinghouse. If we were to subscribe to Sling TV, would we be able to run it on our Westinghouse Roku TV without any additional devices?
