Q: QuestionI'm unfamiliar with the Fire platform. I currently have 2 televisions (older models) to which Roku devices are connected. Can I use my Roku with this TV? May seem silly but wanted to be sure. Thanks!
Asked by Binx.
- A:Answer The TV has HDMI inputs and USB so you could attach ROKU, but why, the fire platform offers the same apps such as Prime, Hulu, Netflix, YouTube, Disney + etc without Roku. You will just need to log into whatever service you are already subscribed to and enable them on the Toshiba.
