Overview
Switching between a detailed ultrawide picture for immersive games and a lower-resolution, very high refresh mode for shooters, this LG OLED curves around the viewer. Its processor upscales lower-resolution sources toward native detail.
Sharp pixel density, deep OLED blacks and dual-mode speed make it suit both cinematic games and editing timelines. Reaching the fastest refresh depends on a graphics card with the latest DisplayPort.
Who it's for
Enthusiast gamers and video editors with modern GPUs who want an immersive wide canvas. Users with small desks or older graphics hardware will not get full value.
Pros and cons
- Very sharp ultrawide OLED
- Switchable high refresh mode
- Very fast pixel response
- Deep blacks with True Black HDR
- Top refresh needs DisplayPort 2.1 GPU
- AI upscaling needs WFHD or higher source
- Contrast ratio listed two ways
Performance notes
Motion clarity comes from the OLED's very fast pixel response, and the dual-mode switch trades resolution for refresh when speed matters most. Brightness and color hold steady in varied room light thanks to the tandem OLED structure.
