Overview
Wrapping a wide curved QD-OLED panel around your view, the Alienware ultrawide pairs a very high refresh rate with extremely fast pixel response for fast games. It ships on a height, tilt and swivel stand with DisplayPort, HDMI and USB upstream cables.
Buy it for OLED contrast and motion clarity in fast shooters and racing games, with a warranty that covers burn-in. The spec table leaves out HDR certification, mount pattern and port versions, so those claims rest on the product title.
Who it's for
Made for desk gamers with a graphics card strong enough to push high frame rates at ultrawide resolution. People who run spreadsheets with fixed taskbars for hours may prefer an LCD that does not risk burn-in.
Pros and cons
- Very fast refresh and response
- Curved ultrawide QD-OLED panel
- Burn-in covered by warranty
- Fully adjustable stand
- Needs a strong GPU for full refresh
- Static images carry OLED burn-in risk
- Mount pattern not listed in specs
- Wide footprint on a desk
Performance notes
Each QD-OLED pixel makes its own light, so blacks are true and response is extremely fast, which removes blur from slow pixel transitions. Reaching the full refresh rate depends on the graphics card delivering matching frame rates at ultrawide resolution. Full-screen brightness is moderate, so bright rooms lean on the matte finish.
