Someone may have suggested this, or something like it, before. I rode with a laptop with two screens and thought it would be great for every single screen item to be a movable and removable widget. Then I could put the rider list, elevation, map, speed readout, etc, on the laptop screen (and be able to eliminate some since they are on the phone) and just the rider on the TV. Then you could add things like a running chat/comment widget too since messages disappear and if you don’t see them there is no way to see what someone said.
How do you stream to your TV? Does Zwift support Chromecast?
probably just using HDMI off the graphics card
