After installing the Qubes 4.2 on the new system, I have the following problem.
When I connect and external monitor, it doesn’t work. Both HDMI and DisplayPort ports are not working.

You cannot use external monitors if you’re in Optimus mode. With NVIDIA cards, that is available only in Discrete mode.

[solved] Qubes 4.2.2 not detecting external monitor - Nvidia RTX 4070

I read the topic and did: add new qube ‘sys-gui’ then in change mode to HVM and then in device tab added Nvidia to list when I run sys-gui, it ask to login to system again then the external monitor goes off. what is my mistake? There’s no chance to use external monitor in Discrete mode Would you please explain more or give me a topic to understand, because I’m not a tech guy.
