What matters

What matters is connection fit, not a faster headline panel. Both are 27-inch-class 3840x2160 QD-OLED displays with 240Hz refresh and an official 0.03ms response-time claim, so the premium does not buy a higher basic resolution or refresh rate.

Key differences

  • The Alienware uses DisplayPort 1.4 with DSC, two HDMI 2.1 inputs including one eARC port, a USB-B upstream hub, three downstream USB-A ports, and one downstream USB-C port limited to 15W charging rather than video input. It suits a gaming-first desk that already has a charger or dock.
  • The ASUS adds DisplayPort 2.1a UHBR20 at 80Gbps, two HDMI 2.1 inputs, USB-C DisplayPort Alt Mode with 90W power delivery, and a three-port USB-A hub. With compatible hardware, one cable can handle laptop video and power, while the higher-bandwidth DisplayPort link can avoid DSC.
  • The same-day US listings were $799.99 for Alienware and $1,099 for ASUS, a $299.01 gap before taxes and fees. ASUS specifies a three-year warranty including panel burn-in, while applicable Alienware QD-OLED three-year terms also include burn-in; the written product-specific terms still control.

Who it is for

  • Choose Alienware when the shared 4K 240Hz gaming experience, DisplayPort or HDMI input, and lower same-day price cover the desk you already own.
  • Choose ASUS when a laptop actually needs USB-C display input and up to 90W of power, or when a compatible GPU and cable can use DisplayPort 2.1a UHBR20.
  • Choose neither when the current display already meets your resolution, refresh, port, and warranty needs, or when mostly static desktop use makes OLED ownership a poor fit.

Watch-outs

  • Recheck both prices in the same market. The $299.01 gap was observed on August 5, 2026, and excludes taxes, shipping, handling, and recycling charges.
  • An 80Gbps DisplayPort specification has no practical benefit unless the GPU and cable support the relevant link rate.
  • Burn-in language does not remove the need for sensible static-content care. Keep the product-specific written service terms from the actual sale.
  • Alienware's downstream USB-C port provides 15W charging, not USB-C video; budget for a separate laptop charger or dock if that is part of the desk.
