Xbox One S is on, but TV Says "No Signal" after updating my Xbox

We moved to another TV and got a new HDMI cable.

We did the Reset as you outlined and it says "No Signal' on the TV.

It is an Xbox one S.

Any other suggestions?

That's the issue right there, Prezdead! My TV auto detects the resolution being put out by the source and sets it accordingly. There is no way to set my TV's HDMI input to display a certain resolution regardless of what the source is putting out. My Android
box and Roku 4 put out a 4k signal when I enable the resolution they should output is 4k. Unfortunately, The XBOX One S doesn't seem to do that.

When I do the video test on the XBOX One. My TV doesn't even flicker. It just pops up that it failed everything, which is incorrect. If I change the resolution on the XBOX One S to 720p, then it flickers and my TV changes the display to 720p. If I change
the XBOX One S to display 1080p, then the TV flickers and changes the resolution to 1080p. If I try to change the XBOX One S to display UHD, it does nothing other than go instantly to the failed screen, which states none of the options are supported. Under
Advanced Video Settings though, I have 24Hz, 50Hz, and UHD 4k checked. the problem is, the XBOX One S is putting out the 4k signal because the test says the TV fails everything and the TV will not disaply in 4k until the TV receives a signal from the XBOX
One S to display in 4k.

Hi, thanks for responding

-It is a regular Xbox One S

-There are no other external devices plugged into my device

-Yes, it says "No signal" on my TV when I turn the Xbox on

-Due to the way my TV is postioned. I am unable to fully removed my HDMI and use another HDMI cable or a different port on my TV

have the same issue with my 50pg20d lg tv ,when I turn on the xbox one it says connecting on the tv then after a few seconds says no signal ,

I have tried a dvd player in the same ports and they work fine only the xbox one wont work any help would be great

I am having this same issue since a recent xbox one update. Tv signal just freezes every so often and occasionally I see a message about my tv not being able to play DHCP content. but if i don't route my tv signal through my xbox then it works fine. hopper
