@Radeon897 can you follow these steps #115 (comment) and send me the output your device supports legacy modes

[Radeon897]

I followed your steps but when checking for the alienware folder in /sys/kernel/debug/ there is no alienware-wmi folder in that directory to cat.

[tr1xem]

@Radeon897 i would need your acpidump

When did u purchase this device?

[Radeon897]

acpidump.txt

I purchased the monitor about a month ago. I provided the full acpidump.

[tr1xem]

Ahhh its a monitor https://github.com/tr1xem/alienfx-linux Lets shift here AWCC(currently) is for only laptops and desktops

Try alienfx-linux It should work
