Why can't the screen above the keyboard on the Asus UX4100E model dual-screen laptop be detected?

Apologies for not checking GitHub for a long time. I noticed that my issue has been closed. This is additional information.

Because Asus' provided control function is too cumbersome, placing the controller on the desktop floating layer where it pops up automatically when the mouse hovers over it greatly affects the user experience. I have also asked the official customer service why they don't place it in the system tray, but they have been avoiding this issue. So can this laptop also support the function of turning off the display, with options such as closing, turning on, and disabling (brightness set to 0), for the monitor with the ID 'DISPLAY\BOE0921\4&33fd3a7c&0&UID4165'?

This is the same issue as #501

[emoacht]

Thank you for the probe.log. This model is quite unique and I am happy to see it. It indicates that the BOE display is connected vis DisplayPort internally and not recognized as an usual internal display. But DDC/CI to that BOE display is not enabled and thus it is uncontrollable by this app. If there is settings for that BOE display in BIOS menu, you can try to change it.

[ShisanXing]

Yeah, that was also the issue I raised.

[ShisanXing]

ok

[ShisanXing]

I just went through the BIOS menu and couldn't find any specific DDC/CI settings. I can control external monitors and the internal main display using it, but the internal DP display cannot be controlled. Thank you anyway.

@emoacht Would you be open to a PR adding Zenbook Duo support? I plan to look into it. If so, can this issue be re-opened?

[emoacht]

If you find a solution and send a PR, I will surely look into it.
