Hello - first post, but I have Roku built in to 4 of my TV's and one Roku 4k box on the last TV. Now, it's time for the minivan for my kids on road trips...
My only concern is how much data the Roku unit will chew through, especially considering that the screens in my minivan are probably no better than 720p. I read about some secret menu for adaptive bitrate, but that doesn't 100% solve my issue. Is there any way to get the unit to connect and stream at a lower BEFORE the signal hits the display? It sounds like a Roku will receive a signal and stream at its highest quality (chewing through bandwidth) and then downgrade the signal if needed to the display. It also sounds as if the adaptive bitrate just tries to throttle the bandwidth, but if the unit is trying to receive for a 4K or hi-def signal, I don't see where that would be too beneficial, and it sounds like others mentioned it doesn't even work always.
I just bought a new Sienna with built-in wifi and was going to try it next weekend, but I need to know if one of the Roku units is better than the others, or can be set up to receive a lower-def signal (i.e. use less bandwidth) per its settings. I did search these forums before posting and did not find the exact answer or information I needed, so any help would be appreciated!
