I am not the OP but you have stated the question I have.
I access the internet via Verizon FIOS. I have no Cable TV subscription, just an internet subscription. I access the internet though a laptop computer. I now own a Roku Smart TV, which includes Apps (such as Hulu) that are useful. But I cannot mirror my laptop screen to my TV using roku. Ideally, I would like to do this thru WiFi.
Sorry, do not use roku. I have a Sony brava TV and can’t seem to mirror to it with anything.
What is OP?
I dont have Roku but use Chromecast and it might work similarly to Roku. I find the media on my computer or pad and start it. In upper right of computer display is Chromecast emblem I click on that and choose the TV to watch it. The info is sent to the TV which uses it to access the internet and stream the show. The computer is no longer needed jts acting as a TV remote rather than passi g the data on to tv. If I mirror the computer my Chromecast device isn’t involved at all
