Overview
LG built this UltraGear around a deeply curved ultrawide OLED panel with fast refresh and webOS, so it streams Netflix and runs cloud games without a PC. A remote is included for smart TV style use.
Wraparound immersion and true OLED blacks make it a strong racing and flight sim screen. The resolution is spread across a very large panel, so desktop text looks less crisp up close.
Who it's for
Immersive gaming and movie watching from a desk suit this curved panel. Spreadsheet and document workers will prefer a sharper, flatter screen.
Pros and cons
- Very immersive wraparound curve
- Fast OLED response
- Built in apps and cloud gaming
- Wide color coverage
- Low pixel density at this size
- Steep curve distorts straight lines
- Large desk footprint
Performance notes
The steep curve places the edges in peripheral vision, which suits racing and flight games. OLED pixels switch almost instantly, so motion stays clear at high frame rates. webOS runs streaming apps on the monitor itself, independent of the PC.
