Overview
Gamers with a large desk and a strong graphics card get a very high resolution curved OLED that wraps around the field of view. A hotkey switches to a lower resolution at very high refresh, and USB-C charges a laptop while carrying video.
Sharp text at this size makes it usable for work as well as immersive games. Driving the full resolution at high frame rates takes a top end GPU.
Who it's for
Sim racers, RPG fans and creators who want a wide canvas get detail and immersion. Gamers with modest hardware or small desks should consider a smaller monitor.
Pros and cons
- Very sharp ultrawide OLED
- Dual Mode for esports
- USB-C laptop charging
- Height, tilt and swivel stand
- Needs a powerful GPU
- Large desk footprint
- Heavy for repositioning
Performance notes
Detail comes from the high pixel count at this size, and the updated subpixel layout reduces color fringing on text. Dual Mode lowers resolution to double the refresh rate, trading sharpness for speed in shooters.
