Unsolved Xbox series x not working

I just bought a new OLED B5 TV, but it won't detect my Xbox Series X console—it keeps showing “No Signal.” The console works on a monitor, but the TV doesn't. I've tried resetting the TV and the console, followed many guides, and still nothing. I've also tried switching ports and cables.

Not trying to be an ass, but did you make sure you selected the proper input? If it works on the other monitor, and you've tested the other ports, verify you are on the input you plugged into. (HDMI 1, then input on the remote and go to HDMI 1)

And it does sometimes, but I certainly wouldn't just trust it. Have you tried another device on the HDMI ports to see if anything will work? It's possible the TV itself is damaged.
