Maybe?? But I’m guessing not. For starters it may depend on which model you have. The next issue is that ones I browsed on their website called these screens “tablets” not TVs.
The user’s guide for one bike made no mention at all of HDMI or ports of any kind other than power. The user’s guide for another one did actually show ports on the tablet and it did have an HDMI port but it was labeled “For displaying on an External Screen”. Unlike many computer ports, video ports tend to be input-only or output-only, and based on the documentation for that bike. It sounds like it is output-only. But if you have a different model, so it may have different features. Do you see a place in the UI of the tablet to select the HDMI port for input?
Banned but back. Because why not?
