LG UltraGear evo 39GX950B
Excellent premium ultrawide OLED for gaming, HDR media, and multitasking; not fully profiled for PWM/coating yet.
A 39-inch 5K2K OLED ultrawide gaming monitor with a 1500R curve, 142 PPI, Dual Mode refresh, and LG’s 5K AI Upscaling. It is aimed at high-end gaming and immersive desktop use rather than bright-room specialist duty.
What this display is best at
- immersive PC gaming
- HDR games and movies
- ultrawide multitasking
- sim racing and cockpit-style setups
- sharp text and desktop productivity
What to know before buying
- 5K2K at 165Hz is demanding on GPU horsepower; the 330Hz mode drops to WFHD.
- Exact coating finish and PWM behavior are still unverified publicly.
- OLED burn-in precautions still apply for static desktop use.

Real-World Interpretation
What the display data means in actual use.
Motion and refresh behavior
Excellent motion for a 39-inch ultrawide: 165Hz native at 5K2K or 330Hz in WFHD with 0.03ms GtG.
Media and HDR fit
Excellent for HDR games and movies thanks to OLED blacks and True Black 500; the 21:9 aspect ratio is immersive but not ideal for all video formats.
Eye comfort context
Likely comfortable for long sessions thanks to OLED contrast and high PPI, but PWM is unprofiled and the large curved panel benefits from a deep desk.
Reading and daily use
Very sharp at 142.5 PPI, making text and spreadsheets look crisp; macOS/Windows scaling will likely be needed for many users at native 5K2K.
