LG 45GX950A-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.

The title image and description is not what it says.This is 2K not 5K its 3440 and its totally misleading.

Absolute beast of a monitor! sure it might not be as sharp as a 4k screen but the immersion of a 39 inch monitor is something beautiful. My last monitor was a 3440x1440, 34 in wide screen and the difference between 34 and 39 is more than you would think. This display is massive. And beautiful, and OLED is sooo much better than the TN panel in my old screen. Gaming is pure joy on this thing.!

This is NOT the 5k2k version of this monitor, like the images and description suggests. It is the older 1440p version. The model number is the only thing that is correct in the description and again matches the older model NOT the 5k2k version.

This monitor works great. It brings OLED-TV picture quality and vivid color to the desktop. Now I get the same feeling watching movies on my monitor as I do on my TV. Text is very sharp, and the image is clear and colorful.The only drawback I can think of is that they should have used an aluminum stand. For a ~$1500 monitor, it deserves it. Therefore, I give it a rating of 4.9/5.Note: I’ve seen people post photos showing unclear text and incorrect colors. I ran into the same issues when using an older PC that doesn’t support 5K2K, or when using the wrong adapter or cable.It works well with a Mac Mini M2, mac pro M4, 2019 Intel i9 Mac Pro, and ThinkPad X1 Extreme using a direct USB-C connection.

Color and brightness are wonderful but that’s about where the fun stops. The text is so incredibly fuzzy and all black objects have a slight yellow halo line. Additionally had a faulty USB-C port on delivery. Have to return it.

Initially received the monitor with severe panel artifacts (second time experiencing this with LG). Almost returned it again, but Pixel Cleaning in the monitor settings fixed it completely. Works great now, but be aware of this issue before buying. For a premium LG monitor, it shouldn’t be like this out of the box.

First off, the curve is VERY aggressive! However, once you sit in front of it, it's nowhere near as bad as you may think. I have yet to try this on PC; it works mostly great on console. You do have to tweak some annoying settings to get it to register HDR and may have to manually adjust the picture quality but it is very worth it! You can either have the image stretched or cut it down to 16:9. I personally recommened the stretched ratio since it doesn't look as terrible as one might think. In some game, however, it is very noticable and should be switched to 16:9 instead of 21:9. The colors and brightness are beautiful, especially in dark rooms. The high refresh rate makes gameplay look simply stunning and easily worth the discounted price. While the original price is crazy, the cut down price makes this monitor a MUST if you want to get into wide screen monitors! The response time feels practically instant compared to other monitors I've used. The height can also be adjusted to very high or average, which helps a lot. Overall, I give this monitor a 9/10; one point is taken off due to the original full price. But if that doesn't bother you, go for it!

It sais 45GX950SA-B in the product detail and on the picture it shows 5k but it's not the 5K model.

I see a few people saying this monitor looks washed out or faded out of the box but that’s just LG playing it safe for VESA compliance. It’s calibrated to pass certification, not to wow you.Here’s what you need to do the moment you unbox it for HDROn the hardware side (monitor settings)Gamer 1 profileChange Black Stabilizer to 25-30. The default is 50, and it makes everything look flat and hazy.Set Brightness to 100 and Peak Brightness to High.Sharpness : 50Run the Windows HDR Calibration Tool.Minimum Luminance :0Max luminance :1260Full Frame Luminance: 270(Optional): Run a manual screen refresh once if you notice banding out of the box.If you want more visual punch, switch to Gamer 2. but personally, I find it too oversaturated. Gamer 1, with the tweaks above, gives you clean contrast, natural skin tones, and sharp text clarity without sacrificing realism.After calibration, this panel looks stunning. The 800R curve is immersive... sit about 31 inches (80 cm) away for the best experience. Too close = eye strain, too far = immersion breaks.I came from a Samsung G9 OLED, and at first this didn’t look as punchy. But once I made these changes? It won me over. And unlike my G9, which failed just after the warranty expired, I feel much more confident with LG’s build.If you’re hesitant or waiting for Black Friday I got mine on Prime Day, and I have zero regrets.
