The consensus
What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, LG's 39GX950B is the new high-water mark for premium ultrawides. Specialist threads on r/OLED_Gaming and r/ultrawidemasterrace point to Monitors Unboxed and TFTCentral coverage praising the 4th-gen tandem W-OLED panel for delivering noticeably higher full-field brightness than previous WOLED ultrawides while keeping the 143 PPI pixel density that finally puts text clarity in the same conversation as 4K monitors. A direct head-to-head writeup on r/ultrawidemasterrace comparing it against the Dell U4025QW concluded the LG won for a mixed productivity-and-gaming workload.
What reviewers liked
- Tandem W-OLED panel praised across r/OLED_Gaming for higher sustained brightness than prior WOLED ultrawides
- 5K2K (5120x2160) at 143 PPI delivers sharp text and UI, addressing the biggest historical OLED-ultrawide complaint
- Dual-mode operation and 165Hz+ refresh well-reviewed by specialist communities for both productivity and gaming
- r/ultrawidemasterrace comparison thread preferred it over the Dell U4025QW for mixed workloads
Where it falls short
- Premium pricing puts it out of reach for most buyers
- r/ultrawidemasterrace commenters flag DisplayPort 2.1 bandwidth as a limitation at this tier
- Aggressive curve takes adjustment for users coming from flat or gentle-curve panels
- All OLEDs carry burn-in risk for users with static UI elements
Across the reviewers we read, LG's 39GX950B is the new high-water mark for premium ultrawides. Specialist threads on r/OLED_Gaming and r/ultrawidemasterrace point to Monitors Unboxed and TFTCentral coverage praising the 4th-gen tandem W-OLED panel for delivering noticeably higher full-field brightness than previous WOLED ultrawides while keeping the 143 PPI pixel density that finally puts text clarity in the same conversation as 4K monitors. A direct head-to-head writeup on r/ultrawidemasterrace comparing it against the Dell U4025QW concluded the LG won for a mixed productivity-and-gaming workload.
The consensus criticisms are predictable for a flagship: it's expensive, the 800R-ish curve is steeper than traditional 1800R ultrawides and takes adjustment, and r/ultrawidemasterrace commenters flagged that at this price/refresh tier the lack of full DisplayPort 2.1 bandwidth headroom feels like a miss. Amazon's rating sits at 3.8 across only 11 reviews, which is too thin a sample to weigh heavily against the broader specialist-community enthusiasm.
