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.
