I tried to connect my cell phone to my TV, but also to my Xbox 360 and it didn't work
I have a Samsung and tried to connect it somehow with the charging cable, but that didn't work either.
I don't have an extra cable.
in addition, neither the Xbox nor the television has internet of any kind
do you need a certain app or something?
Smart TVs can be connected to cell phones via WLAN, normal ones can't.
The Xbox 360 does have Wi-Fi, or do you have the elite or arcade version?
