- Noticeable VRR flicker can occur with changing refresh rates during gameplay.
- The 800R curvature is aggressive and may not suit all users or viewing preferences.
- The stand likely only offers tilt adjustment, limiting ergonomic flexibility.

Dimension Scores
The 5K2K OLED panel offers 1.5M:1 contrast, deep blacks, 98.5% DCI-P3 color coverage, and 1300 nits peak brightness, though bright colors are less vivid.
With a 0.03ms (GtG) response time and Dual Mode offering 165Hz at 5K2K or 330Hz at WFHD, it delivers near-instantaneous and fluid motion.
It features DisplayPort 2.1, two HDMI 2.1 ports, and USB Type-C with 90W power delivery, providing cutting-edge connectivity.
The monitor's stand appears to offer only tilt adjustment, lacking height, swivel, or pivot for comprehensive ergonomic positioning.
Best For
- PC gamers who play both graphically intensive story-driven games and competitive FPS titles.
- Users requiring a large, high-resolution ultrawide display for multitasking and productivity.
- Individuals seeking deep blacks and high contrast for cinematic content viewing.
Not Recommended For
- Budget-conscious buyers, given its premium price band.
- Users sensitive to aggressive screen curvature or who prefer flat panels.
- Professionals whose work demands absolute color accuracy for bright hues.
Watch Out For
- Bright colors aren't the most vivid, which can make some HDR content appear less impactful than on other displays.
- Noticeable VRR flicker can be present when the refresh rate changes, potentially disrupting immersion in games.
- The 800R curve is very pronounced; if you're not used to such a tight curve, it might feel overwhelming or distort content initially.
- While LG offers a two-year warranty for the OLED panel in the US, burn-in remains a long-term concern for OLED technology, especially with static UI elements.

What Buyers Say
Users are generally drawn to the monitor's unique 5K2K OLED panel and its dual-mode refresh rate capabilities, which provide flexibility for different gaming genres. The sharp text clarity, attributed to its 125 PPI and updated subpixel layout, is a recurring point of appreciation for both work and gaming. However, some users have noted that bright colors lack vividness and that VRR flicker can be noticeable during gameplay. The aggressive 800R curve is a defining feature that some find incredibly immersive, while others might find it too intense.
“Dude, this 5K2K OLED is insane for gaming, like, the blacks are so deep, but sometimes I wish the bright stuff popped a bit more, and that curve is WILD. Still, 330Hz for Valorant? Yes please!”

Buying Guide
When looking at a monitor like this, you're buying into a specific experience. The '5K2K' resolution means a ton of pixels, giving you a huge workspace or incredibly detailed game worlds. 'OLED' means perfect blacks and amazing contrast, making everything look super punchy. The 'refresh rate' (165Hz or 330Hz) tells you how many times the screen updates per second; higher numbers mean smoother motion, especially in fast games. 'Response time' (0.03ms) is how quickly pixels change color, crucial for avoiding blur.
5K2K WUHD (5120 x 2160) Resolution
This isn't just 'more pixels'; it's a wider canvas. Imagine having two 2560x1080 monitors seamlessly stitched together, but with even more vertical space than a typical ultrawide. It's like upgrading from a small painting to a panoramic mural for your desktop.
0.03ms (GtG) Response Time
Think of this as how quickly the monitor reacts to what your computer tells it to do. A 0.03ms response time is practically instant, meaning there's almost no 'ghosting' or blur behind moving objects, which is critical for competitive gaming where every millisecond counts.
Dual Mode (165Hz WUHD / 330Hz WFHD)
This is like having two monitors in one. You can enjoy the full, detailed 5K2K resolution at a fast 165Hz for single-player games or productivity. Then, with a hotkey, you can switch to a lower resolution (2560x1080) but a blistering 330Hz for twitch shooters, giving you the best of both worlds without needing two separate displays.
800R Curved Screen
The 'R' stands for radius, and 800R is a very aggressive curve. It means the screen wraps around you more intensely than a 1000R or 1800R curve. This is designed to fill your peripheral vision, pulling you deeper into games and making the edges of the screen feel closer, but it's a personal preference and can take some getting used to.
Alternatives
If this monitor's aggressive curve or specific resolution isn't for you, look for ultrawide OLEDs with a less pronounced curve (e.g., 1800R), or consider a 16:9 4K OLED if you prefer a traditional aspect ratio with high pixel density.
