There are any cons/downsides to change the display on the xbox series x from auto detect to...

good night

there is no cost to opt for another option other than the automatic one, it's just a matter of practicality.

Upon changing the Display Overrides from Auto-Detect to HDMI, the picture changed to a 640 x 480 resolution and 4K was not an available option. Interesting!

Thoughts??

Thanks again Sammy!

I was having the same problem , i did everything, played the game for an hour say on 1080p cause it doesn't think my LG c2 don't support 4k and the rest , I changed my settings to hdmi only on the Xbox series x settings , in order to play in 1080p full screen , I then went back to TV and display settings and changed it auto detect overrides setting and then allowed me to turn everything on , tick everything, so it kinda feels like it's to do with the auto detect (recommended) display settings, it's weird , Microsoft please look in to this , thanks

Also, sorry I forget to add I change originally from auto detect to HDMI back to auto detect via my xbox display settings would that have made a difference to why it wont work?

I changed my display settings from HDMI to Auto-detect and it appears to have resolved the issue.
