What matters

Both monitors use 31.6-inch 3840x2160 QD-OLED panels with official 0.03ms response-time claims, so this is not a basic panel-quality choice. It is a workflow split: a flat 120Hz screen with laptop charging and built-in audio, or a curved 240Hz screen with a gaming-focused input layout.

Key differences

  • The flat 120Hz S3225QC accepts video over USB-C with up to 90W power delivery and adds a five-speaker 25W audio system. One cable can handle display and charging for many laptops, while built-in sound removes another device from a mixed work-and-media desk.
  • The AW3225QF pairs a 1700R curve and 240Hz refresh rate with DisplayPort 1.4 and two HDMI 2.1 inputs, including one eARC connection. That raises the motion and device ceiling for a capable gaming setup, but the monitor has no built-in speakers and therefore needs an external audio plan.
  • Dell US listed the S3225QC at $599.99 and the AW3225QF at $849.99 on August 4, 2026, a $250 difference. Because the core QD-OLED panel baseline is similar, the premium mainly pays for the Alienware model's curvature, refresh rate, and input layout; buyers who cannot use 240Hz should not pay it by default.

Who it is for

  • Choose the S3225QC when a USB-C laptop is the main source, its power need is no more than 90W, and built-in audio matters more than maximum refresh rate.
  • Choose the AW3225QF when a PC and games can genuinely use 240Hz, the 1700R curve suits the setup, and two HDMI 2.1 inputs plus DisplayPort 1.4 are worth the higher same-day price and separate audio.
  • Choose neither by default if OLED care around persistent static content does not fit your use, or if neither monitor's port and audio arrangement matches the desk you actually want.

Watch-outs

  • The $599.99 and $849.99 figures are a Dell US snapshot from August 4, 2026. Recheck local pricing and warranty terms before buying.
  • The S3225QC is not a full dock: it lists one HDMI 2.1 input and two downstream USB-C ports, but no Ethernet or USB-A port.
  • The AW3225QF's 240Hz ceiling matters only when the source device and games support it, and its lack of built-in speakers adds a separate audio requirement.
  • Both are QD-OLED monitors. Buyers who do not want to manage OLED care for static desktop content should pause before choosing either one.
