Laptop with 2 external monitors

[Sylvain Archenault]

Hi,

I'm have a laptop with Intel HD 620 graphic card and i'm trying to set
it up with 2 external monitors. So i have a usb-c hub where i connect
the first monitor with HDMI and the second one with DP. I'm able to have
both of them work with the following resolutions:
        - 1920x1080 : internal display
        - 1920x1080 @ 60Hz : hdmi display)
        - 1920x1200 : DP display

Having said that the DP monitor can go up to 2560x1440 but I'm unable to
use that resolution with the order monitor active. I only see this in
the log:

/usr/libexec/gdm-x-session[1069250]: (EE) modeset(0): failed to set
mode: Invalid argument

Based on
https://www.intel.com/content/www/us/en/support/articles/000025675/graphics-drivers.html
I thought it would be possible to use the highest resolution.

If I disable the HDMI display, I can go up to the max resolution.

Is there something i'm missing? or somewhere I could look to confirm my
graphic card/system doesn't support the configuration I'm trying to do?

Thanks
