Need help, HDMI port does not use Nvidia Mx250 but intel UHD, trying to run 5120x1440 DUOux481FL

System: Asus Zenbook Duo UX481FL
Battery or AC:

Frequency of occurrence:

Detailed description：Hi Everyone,
I have to manually reconnect the HDMI cable when the computer restarts to ensure I get 5120x1440 working (only at 29hz)
Otherwise the computer will start at a random resolution that is 1080 or 4k. It is strange that it changes all of the time.

Even when I am running it at 5120x1440 it is using Intel UHD, how can I change this to Nvidia MX250?
Thanks

Hello Seevip2,
The maximum resolution and frequency that the HDMI on this device exports is 1920x1080 @ 60Hz,
and it is using the Intel VGA card to export.
Thank you.
