Refresh rate 480Hz works as advertised. OLED blacks very deep. Colours need some tuning out of the box but are beautiful once calibrated. G-sync works great. Minor VRR flicking but only occurs in a few situations and never during actual gameplay, usually just in menu screens. Very easy setup. Stand works amazing and is sturdy. ### ⭐⭐⭐⭐⭐ A great display if you know what you're looking for *by C***E on 4 December 2025* 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. ## Frequently Bought Together - LG 27GX790A-B 27-inch Ultragear OLED Gaming Monitor QHD 1440p 480Hz, 0.03ms, DisplayPort 2.1, True Black 400, NVIDIA G-Sync, AMD FreeSync Premium Pro, HDMI, USB, Tilt/Height/Swivel/Pivot Stand, Black - Silkland 80Gbps DisplayPort Cable 2.1 6.6FT [VESA Certified], [8K@240Hz, 4K@540Hz 360Hz 240Hz] DP 2.1 Cable 16K, DP80 HDR DSC Display Port Cord Compatible FreeSync Gaming Monitor 5090 7900XTX, S1334 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/740468595-lg-27gx790a-b-27-inch-ultragear-oled-gaming-monitor-qhd](https://www.desertcart.us/products/740468595-lg-27gx790a-b-27-inch-ultragear-oled-gaming-monitor-qhd) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-21*
