What owners think
The Word on the Street
The proof
Performance
The 0.03ms response time is basically instant, and the 165Hz refresh rate keeps everything buttery smooth. What surprised us most is the AI upscaling. It actually works. Feed it a 1440p signal and it sharpens things up to near-native 5K2K quality without needing a GPU upgrade. The MLA+ panel tech also pushes brightness higher than typical OLEDs, which helps in brighter rooms. This thing sits in the 97th percentile for performance, and it shows.

vs Competition
The ASUS ROG Strix XG27UCDMG is a 27-inch 4K OLED that's faster on paper but tiny by comparison. The MSI MAG 271QPX QD-OLED E2 is a great budget OLED, but it's 1440p and flat. The Samsung Odyssey G60SD is a solid 1440p ultrawide, but it can't touch the 5K2K resolution here. The Dell UltraSharp U4025QW is the closest competitor for productivity, but it's 60Hz and not OLED. For pure gaming immersion, the LG wins.

Price
Value & Pricing
At $2,000 USD, this is not a casual purchase. But for what you get, it's actually reasonable. A 5K2K OLED with this refresh rate and response time would have cost double a few years ago. If you're a serious gamer or content creator who wants one display for everything, this earns its price tag.

Overview
The LG UltraGear evo 45GX950B-B is a monster of a monitor, and I mean that in the best way. It's a 44.5-inch 5K2K OLED that wraps around your face with an 800R curve, and it's easily one of the most immersive gaming displays we've ever tested. The headline here is the resolution: 5120 x 2160 on an OLED panel with a 165Hz refresh rate. That's a combination that simply didn't exist until recently, and LG nailed it.
Common Questions
Q: Is this using a Tandem OLED display?
No, it's using LG's MLA+ (Micro Lens Array Plus) OLED panel, not the newer Tandem OLED tech. MLA+ helps boost brightness by reducing light loss, but it's not the same as the dual-stack Tandem panels in some newer laptops and tablets.
Q: Can my GPU handle 5K2K at 165Hz?
Most modern GPUs can push 5K2K at 165Hz for esports titles, but AAA games will need DLSS or FSR to hit high frame rates. The built-in AI upscaling helps too, so you don't need a flagship GPU to enjoy it.
Q: Is the 800R curve too aggressive?
For gaming, it's fantastic. For productivity work like spreadsheets or video editing, some people find it a bit much. If you do mostly work and light gaming, a gentler curve or flat panel might be better.
Who Should Skip This
If you're looking for a productivity monitor for office work, this isn't it. The aggressive 800R curve and OLED burn-in risk make it a poor fit for all-day spreadsheet duty. Go get a Dell UltraSharp U4025QW or a flat IPS panel instead.
Verdict
The LG UltraGear evo 45GX950B-B is the best ultrawide gaming monitor we've tested, period. The 5K2K OLED panel, 165Hz refresh rate, and AI upscaling combine into something genuinely special. If you have the desk space and the budget, this is the one to get.
