tv says not supported when i try to watch tv

The Live TV is a tricky monster. I definitely recommend paying close attention to all instructions.

Hey there brandomori!

Sorry to hear about the issue! First, I recommend trying the steps listed in our Live TV troubleshooting page.
If the issue continues to occur, I recommend making a post in the Xbox One Preview Forum. This way the proper folks can address the issue. Thanks in advance!

btw im on xbox one preiview if that might be cause of it?

Now it is not working on any TV I try after working on other TVs for a little bit. Black bars now appear on the sides of all the TVs when trying to watch TV through the Xbox.

Check if the tv is not defective or try to change the cable... if it doesn´t work, test another TV to make sure the problem isn´t with the xbox itself.

Issue is with software. Have this issue on Xbox One X with Hauppauge tuner and two Xbox One S with their own Hauppauge tuners. All separate and complete setups. Not TV or cable related since they all stopped working the evening of May 5th.

Yeah I got the same message to try another TV, When I turned on the Xbox this morning I got the splash screen to set up my TV to watch tv which was strange!!!! How can it be the TV when everything else works on the TV and I have the Antenna coax connected
to my TV and watching OTA. It's on Microsoft's end!! I bet they are not supporting OTA through the Xbox anymore due to the Series X is not going to have HDMI in and no OTA support. Probably just weening us off of watching TV through our Xbox which I am
more than disappointed with!!!
