[NAME] you were provided incorrect information. You don't need an Alienware PC to control the lights on your Alienware monitor. There are two variants of AWCC (Alienware Command Center). One for Dell PCs (Alienware or Inspiron G5 desktop) and the Windows store generic version for non-Dell PCs. Go here  to get the AWCC Alienware Gaming Monitor Control Center driver 2.0.1.3 and then the supported AWCC for your AW2521HFL.  And then don't forget, AWCC will not recognize your AW2521HFL unless you connect a USB 3.0 upstream cable from the AW2521HFL to the PC.
Hi, purchased the Alienware AW2521HFL 2 days ago and having some minor issues with it. The AWCC (Alienware Command Center) doesn't detect the monitor ("No supported AlienFX device were detected.") Tried to install the drivers, but the setup wizard doesn't detect it as well. My PC detects the monitor, as I can see it in the "Display settings" when setting up multiple screens, and also in the audio settings. Next issue is, the monitor doesn't deliver any audio. Not from my PC and and not from my PS4. Connected to PS4 via HDMI cable. When connected to PC: Connected via DP on both ends (monitor and GPU port). RTX 2060 Super I don't have any problems with other audio devices, have a BENQ monitor connected to the HDMI port on PC and audio is fine. Haven't tried connecting HDMI to the Alienware yet, but it should work on DP as far as I know. Monitor's volume is on 100 of course so it's not on mute or anything. Would appreciate your help with this, Thanks in advance!
