TV resolution issue with xBox One S

Hi

Please see the list below of supported television resolutions for the Xbox One and Xbox One S.

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.

Hey there!

Have you gone through the steps and suggestions on our
Troubleshoot 4K on Xbox One S support page? One of the steps mentioned is setting the TV Resolution on your Xbox One S to 1080p, while ensuring the 'Allow 4K' box is checked within 'Advanced TV' settings. The TV resolution setting is specifically for setting
how non 4K content is scaled, and will still allow native 4K content to play at 4K on your display.

If the flicker issues persist with native 4K content after setting your TV resolution setting to 1080p, please post back the brand and model number of your 4K display so we can take a deeper look!

No optical, no receiver, just a single HDMI

Thanks for that. We did try several different HDMI cables just to make sure. Not in the market to upgrade the TV right now, which is why I went with the 1S instead of the X, but this is annoying so maybe I'll re-think it. Thank you for your help.
