Let me tell you about the hell that is Roku. They create so much wireless interference and I can’t just get rid of them.
The problem stems from WiFi direct. They automatically scan for the busiest channel and then broadcast full strength on that channel. I don’t know why they do this but it creates a crazy amount of interference.
And before you ask, no you can’t turn WiFi direct off. Also the remote uses WiFi direct for some reason.
WHY, ROKU WHY!
You’re much better off with a mini PC running Linux and Kodi.
I have a mini PC running linux and I use it for streaming (including a Jellyfin library) and gaming. I love it and use it almost exclusively. However I have not gone down the rabbit hole of HDR and Dolby Vision for 4K DRM content.
I have a Google TV stick for that content, which is very far from ideal, I know. But in fairness I find myself barely ever using it.
If 4K and Dolby is important, I saw someone else recommending an Apple TV box as you can easily disable telemetry and the device isn’t riddled with advertising or tracking, but then the apps you download would still be a law until themselves. But probably way better than Roku, Amazon and Google et al?
I have an Nvidia shield for now, and run Plex on unRAID. I will be moving to a HTPC one the shield goes tits up. For the most part, I consume my media from my PC, but if I’m using the TV, it’s currently my shield.
