LG45GX950A-B 45-inch Ultragear 5K2K WUHD (5120 x 2160) OLED Curved Gaming Monitor, Dual-Mode, 165Hz, 0.03ms, NVIDIA G-Sync, AMD FreeSync Premium Pro, HDR True Black 400, USB Type-C 90W, DP2.1, Black

First ImpressionsAfter waiting for the perfect monitor for over 5 years, the LG 45GX950A has exceeded all expectations. It’s not just a monitor—it’s a full-on experience. This 45” OLED monitor is in a class of its own and is a huge upgrade that was well worth the wait. It's large and immersive enough to double as a TV.Performance & Display QualityPlaying games on an OLED panel at 165Hz with this resolution is unprecedented. Text is razor-sharp and extremely legible at 125 PPI. The tiny pixels make individual RGB subpixels invisible even under a magnifying glass. The default brightness is set at 100%, which can be harsh on the eyes, but reducing it to 50% creates a comfortable and rich viewing experience.Design & BuildThe matte finish is an excellent choice, minimizing reflections during daytime use or nighttime movie viewing. Unlike glossy screens with aggressive curves that can reflect the room or even distort the monitor’s own image, the matte surface eliminates internal glare and reflection, which can be problematic on an 800R curve. The monitor also features a stylish, hexagonal customizable LED backlight, and the black rear cover helps minimize ambient light scatter, unlike white back panels.Features & FunctionalityA key improvement over my old LG monitor is the convenience factor. The 45GX950A auto-switches to the active input source—a welcome change from having to switch manually. Also, DisplayPort now carries audio to the internal speakers, which are surprisingly loud and adequate for everyday use.Gaming ExperienceThe 21:9 ultrawide aspect ratio is perfect for cinematic content and immersive gameplay. With a 0.03 ms response time and support for up to 165Hz (330Hz with overclocking), this monitor is lightning-fast. The wider field of view is especially ideal for racing sims, flight sims, and open-world titles. If you've never gamed on an OLED display, the difference in black depth and contrast will feel almost surreal.Power EfficiencyDespite its size and capabilities, the monitor uses only 35 watts for non-gaming activity and 40 watts during gaming when HDR brightness is at 50%. That’s incredibly efficient and allows it to run cool even during extended use.Pros:1. You will feel very giddy at first – in a good way. The curve feels dramatic but quickly becomes natural and immersive.2. Blazing speed: 165Hz/330Hz refresh and 0.03 ms response time.3. Convenience: Auto input switching and DisplayPort audio.4. Cinematic ultrawide 21:9 ratio with a vertical 2160 resolution.5. Immersive and ideal for games and movies with deeper blacks.6. Low power usage and high efficiency.7. Matte finish eliminates distracting reflections.8. Customizable backlight with functional design choices like the black rear panel.Cons:1. A faint white vertical bar appeared at first, but OLED Image Cleaning resolved it quickly.2. On the pricey side, though the feature set justifies the cost.3. Your GPU or CPU may need upgrading to handle the full 5K2K resolution.4. For uncompressed DisplayPort 2.0/2.1 support, you’ll need an RTX 5000 or RX 7000 series card.Final ThoughtsIf you're looking for a monitor that blends stunning visuals, fast refresh rates, immersive curvature, and premium build quality—this is it. I didn’t get to see this in person before buying, but after using it for a day, I can confidently say I will be more than 100% satisfied with it for years to come. Highly recommended.

I never pre-order, but, apprehension due incoming tariffs, compelled me to pre-order so my purchase price would be locked in in case of a tariff-induced price increase. It took 3 weeks to finally get here, and, I'm both relieved, and excited to report this monitor is beyond astounding.Picture quality and response times are top tier.This was intended for use with a new laptop, but, new laptop hasn't arrived yet, and I'm happy to find this monitor will even work with a 10-year-old laptop. This was quite the relief because an additional monitor from another other brand I ordered was either defective, or, just didn't work with this old laptop, so, I sent that other brand monitor back.Anyway, I'm very glad this will work with old laptop until new one arrives.

The picture is quality is the most beautiful I've seen in a monitor. Not sure what the reviewer below was on about because the resolution is exactly as advertised.It fits comfortably in the same space as a 38" ultrawide I've replaced, but with SO much more screen space.My only very minor complaint is that the included stand doesn't adjust down quite as far as I'd like. But the stand is very high quality with a beefy metal base.

This is an awesome looking monitor but I have a few things that make it return worthy:1. First and MOST important: The monitor itself is emitting a high frequency sound that could result in hearing damage or at least temporary Tinitus over time. If you are sensitive to that sort of thing, stay away from this monitor. The sound seems to be coming more from the left and could be a fan or just a crappy component emitting noise.2. Speakers in the monitor are terrible, they shouldn't be there at all.3. LG Software and driver support isn't great on monitors and that's true with this monitor. Especially on MacOS.4. This monitor plays OK with MacOS, and but again we run into Mac scaling issues. Text is clear and sharp, HDR only works on M1/M2 at lower resolutions or lower refresh rates. You need an M3 to take full advantage of this monitors resolution and HDR with variable frame-rate on MacOS.5. Media (even 4k) can look grainy because of the high resolution and short distances - it's ok for media viewing but not as great as hoped.Lastly, I think I'd rather settle for a smaller QD-OLED which is something LG really should have put in this monitor.For the money, I expected to love the monitor with little to no compromises that would make me consider returning it.

Just received the monitor today right out of the box, it has a vertical line.

Absolutely incredible image. That's why we buy LG though. I did sit it right next to the exact same monitor in the 4K version and you can tell anybody that says you can't tell the difference between 4K and 5K just doesn't have enough money... If you want basically the best gaming motor on the planet by this the curves a little bit different than the 4K version so that's infuriating. But overall high quality monitor. I do believe you will need a 50 series graphics card with a 2.1 DisplayPort cable to run this though

This is the ultimate monitor. Gaming, productivity it does it all. Controls are easy to use.

Exceeding my expectations, just the right size and aspect ratio. Amazing looking and love that USB-c port/hub/charger.
