Review: A great display if you know what you're looking for - Overall, this display is absolutely fantastic. I would highly recommend that anyone considering it understand the differences between QD-OLED (Samsung panels; most OLED monitors) and W-OLED (LG) panels. It is also worth learning about the differences between matte and glossy coatings and how they affect the image. The build quality is great; the stand goes together very easily and is extremely solid. It also offers a wide range of height and tilt adjustment. The light on the rear of the housing is a nice touch and has a good selection of colors. Since this is a W-OLED display, the blacks remain perfectly dark even in a bright room. Colors are as good as you'd expect. When the unit first powers on, expect to see some mild to moderate unevenness in the brightness of the image. My unit had some vertical banding which disappeared after a few hours of normal use and an image cleaning cycle. Do not worry if you see something similar on yours! It goes away quickly. Also, there is no discernible text fringing at all. Text does appear somewhat soft, but disabling ClearType in Windows completely fixes this. The image is plenty bright, and HDR content looks great. You can adjust the peak brightness in the settings, so if it seems dim then try that. It is definitely not as bright as a QD-OLED panel, but the perfect blacks make up for this. Keep in mind that bright elements that take up large parts of the screen will cause global dimming. This is normal behavior. The only complaint I have is that the matte coating is somewhat grainy. It is barely discernible at normal viewing distances, and with dynamic content it's even harder to spot; it is most noticeable on static bright pages. Use dark mode whenever you can (which is also good practice for OLED panels generally). For me, the lack of distracting reflections is well worth it. Consider your options carefully when picking an OLED display. There are trade-offs no matter what you choose. If you're looking for a 4K display with a fantastic refresh rate (and 480hz at 1080p!), and you know that the downsides won't be an issue for you, then this is one of your best options.
Review: Mixed emotions but still a good product. - This monitor is gorgeous. Its a very amazing OLED with good response time and a great refreshrate however i have a 4090 and mainly play cs2 and it just doesnt feel like I really got that much more of a boost coming from 240hz. I didnt expect a night and day difference and it could be the game (cs2 is buns with the sub tick system) even on my desktop I still can see my mouse having like a trail (not ghosting) where it just seems like a lower refresh maybe ive gotten to used to super high ones but idk. Overall I would recommend this monitor if its on sale, yoy are upgrading from below 240hz and you want an oled. If you have the 240hz OLED model id probably keep it or find another brand with a higher refreshrate.

### ⭐⭐⭐⭐⭐ The 4K OLED of my dreams!
*by B***N on October 20, 2025*

- Color accuracy: Respectable, great even. Slightly off compared to my production grade monitor, but just as they were advertised! Bravo! - Peak nits: Fantastic, these are the best nits. Everybody knows it. - Refresh rates: So fast you can't even see them. (240hz@4K - 480@1080p - SILKY SMOOTH!!!) - Response time: Not haunted. No ghosts here. - Pixels: There's a lot of them, trust me. Kept losing count otherwise I'd tell you. - Features: One firmware update away from perfection. Pictured is the difference between an LG 27GN950 (left, a 4K edge-lit IPS) and this monitor (right, a 4K MLA OLED). LOOK AT THOSE BLACKS!!! Left is Task Manager on a completely black background, right is a movie during a scene showing complete blacks. Having never owned an OLED before, I couldn't be happier with the decision to go with this monitor. The matte finish obliterates all but the brightest ambient light you would typically throw at it, maintaining excellent blacks and punchy colors. If you're on the fence, just DO IT!
