Hi [NAME] welcome to this free user to user Alienware laptop discussion forum. This is not Dell Support.  Please have a look at Alienware Graphic Amplifier (AGA) and the RTX 3000 Ti Series - My Experience : Alienware (reddit.com) Note they are running Windows 11 and the NVidia Game Read 511.79 drivers released 02/14/2022, so the very most recent.  The Alienware Graphics Amplifier driver update Version: 7.0.4 (28 January 2021) runs on Windows 11 and was last downloaded on 25 June 2022. Alienware graphics amplifier driver update (neutechcomputerservices.com)  
I bought the Alienware 17 R3 computer with the AGA (Alienware Graphics Amplifier). It all worked fine with Windows 8.1. The computer died so I got another 17 R3 with Windows 10 and upgraded to Windows 11. Now it seems that I cannot use my AGA because Dell does not support AGA anymore. Windows 10 was the last update. So now I have a 17 R3 that overheats, and a useless AGA with an equally useless 2070 card (the same in the computer). Isn't modern technology wonderful and expensive? I just want to go back to Windows 10. Any ideas would be appreciated.
17 R3, Windows 11, no longer supports AGA?
