How to play World of Warcraft at 5120 x 1440 resolution on Fullscreen Mode?

Hi:

I recently purchased the Samsung 49” Odyssey G9 ultra-widescreen monitor, and I can set my MacBook Pro M1 Max to a resolution of 5120 x 1440 to the monitor.

However, for some reason, World of Warcraft does not display this resolution option, the highest available resolution is 2560 x 1440.

Is World of Warcraft on Mac restricted to this lower resolution?

Thank you.

For some reason, I’m able to bug the Graphics Options and I can set 5120 x 1440 only on Windowed Display Mode.

No idea how to set the resolution on Fullscreen.

I’d imagine you’d have to fiddle with spaces settings. it might be treating that display as two spaces instead of a single space

But I don’t wanna play on Windowed mode.

My question is more about: how to play on Fullscreen mode with 5120 x 1440 resolution on Mac?

Edit: I already updated the post’s title.
