They have a bunch of secret menus - e.g., see www.techtimes.com/articles/162197/20160531/access-secret-menus-roku-device.htm or just search a search engine for "Roku" and "Secret Menu".Does Roku have a hidden menu like Fire TV devices that show the resolution, refresh rate, and bitrate of whatever is streaming at the moment? Is there an easy way to get this info on a Roku?
I don't know if they give you what you want. Rokus aren't all that expert freindly.
