@oleguer The CEA video modes you're referring to are set via tvservice, which doesn't work correctly on the Pi4 so those set of video modes are not available. The runcommand launch menu shows the resolutions that your TV reports it supports - that's what is offered for the video mode change.

You can set still a custom resolution via config.txt (see https://www.raspberrypi.org/documentation/configuration/hdmi-config.md) if you wish to use a video mode not reported by your TV.
