I changed the resolution to 1080p120 and now my series s doesnt work on another screen

So i took my xbox series s for a couple days and played it on a 1440p144hz screen. Which means i could play the xbox on 120 hz. But now i went back to my old screen and it doesnt display the screen anymore.
Is this because i changed it to 1080p120 and never changed it back?

just need to reset your consoles display settings https://support.xbox.com/en-US/help/hardware-network/display-sound/tv-or-monitor-screen-is-blank-while-connected

OK, so what you need to do is you need to go back to your old TV? And switch your resolution back all it is is just that some TVs can automatically adjust the resolutions if that happens just switched to a TV that supported and change it back to your the resolution needed
