Should I have 50hz and 24hz turned off?

I’d recommend you keep it on if you want the best performan e, but if you want a more stable performance, go to 50 Hz.

I have mine set to 50hz and it works fine, it just depends on your hardware.

Hello, you can find the solution in the following link:

It would be 60Hz exactly. It's a standard refresh rate. In regards to 120Hz, there some different timings, not all of which the Xbox One X or newer Series X/S consoles support. If your display is 119.88 the Xbox won't support it as it's not a standard refresh,
although it may do in the future.

If your display can't change its refresh rate to 50Hz or 24Hz it will have to remain at 60Hz. It may be possible to play 24Hz, but you'll have to turn off VRR as this is usually beyond the scope of FreeSync.

50Hz is for TV content or documentary video on DVD, usually only found in Europe and Asian regions. 24Hz is common for movies and movie streaming worldwide on DVD, Blu-ray and streaming as films are usually recorded at 24 frames per second. If your display
can't change to 24Hz, video playback won't play as smooth.

Hi,

The 50hz and 24hz are for TV and Blu-ray/DVD playback only. With these enabled, the console will automatically switch to these modes if your content is designed to play at that refresh rate.

It does this to provide smooth playback. For example, movies are typically shot at 24 frames per second, if you play back a 24 fps video on a display running at 60hz, or 60 frames per second, it won't look right, you'll get a horrid 'judder effect' and the
audio will be out of sync with the video. The 24hz setting corrects this, so you should get seamless playback, no judder and audio in perfect sync.

Games always use the 60hz mode. Leave them checked.
