Owners of a AW3821DW Alienware monitor may experience the screen flickering whenever it is connected to any Alienware computer, Mac Book Pro, or Mac Mini.
The issue may persist after a factory reset and swapping out the cables and ports in use.
Identify if your computer runs the Windows or Apple operating system: For Windows computers, select the highest refresh rate available: Use DisplayPort (DP) instead of HDMI. For an HDMI connection, it can increase the refresh rate from 60 Hz to 85 Hz only. For a DisplayPort connection, it can increase from 60 Hz to 85 Hz , 100 Hz , 120 Hz, or 144 Hz . For Apple computers, select the highest refresh rate available: The refresh rate is greater than or equal to 60 Hz. Note : Alienware monitors with G-Sync may not work when a USB type-C to a DP or HDMI adapter or Dock is connected. Do not use a USB type-C to a DP or HDMI adapter or Dock. Connect the DP or HDMI cable directly from the computer to the monitor.
