Okay till it broke

Had some screen tearing before complete failure after one month of daily use; LG support says I have to wait a month till they can even see if the parts come off back order and if they can repair it. Even with the LG "premium" care Also, the AI scene optimization feature typically would flicker between slightly brighter and darker images on a 4090 and 5090 Video card while using it for non-gaming use. I found it best to turn that feature off. Besides that, the perfect size/ratio OLED looked great

An Incredibly Immersive Gaming Experience

[This review was collected as part of a promotion.] I've been really impressed with the LG 39GX950B-B. The performance is excellent, especially when gaming. Playing Forza Horizon 6 feels incredibly smooth thanks to the high refresh rate, and the resolution is stunning, making the experience feel really immersive. Connectivity is another strong point. It offers plenty of connection options, and the Dual Mode feature is particularly useful as it lets me easily connect and use my laptop alongside my main setup. The setup process was very straightforward and didn't take long at all. The only thing worth noting is that the power supply comes with a fairly large power adapter, so you'll want to make sure you have somewhere to hide or manage it neatly. Overall, it's a fantastic durable monitor with outstanding gaming performance, excellent image quality, versatile connectivity, and an easy setup process. I cannot see any limitations and I would highly recommend it.

Best PC Monitor for Gaming

[This review was collected as part of a promotion.] A terrific addition to my PC rig. I fly msfs 2024 an awful lot. A bit on the high side fir coat but what a massive enhancement to this flight sim. Had a 27" flat monitor previously. It takes a bit of setting up/configuring, but once done, absolutely well worth a bit of time doing so. Marvelous visuals and ths 39" 1500R curve is spot on for my flight sim. Colour, the blacks are exceptional. And it's a 5K/2K resolution. As you can guess, highly recommended for gamers. Word if caution, you'll require a piweful GPU to run it at 5K/2K Resolution. I have the GEFORCE RTX 5080.

I'm obsessed with this monitor!

[This review was collected as part of a promotion.] I've been using the EVO GX9 5K2K OLED Gaming Monitor for about a week now and I've honestly been loving it. The picture quality looks amazing, games feel super immersive, and the ultra wide screen has been great for both gaming and everyday use.

Imazing Picture Quality but Unreliable

The monitor failed 10 days after I received it, failed again 3 months after LG fixed it, then failed again for the 3rd time a week after the 2nd fix. All 3 times were due to the Cooling Unit not functioning properly. It's unacceptable to have to send the monitor back 3x for the same problem. I expect a lot more from LG in both product quality and how it treats its customers. Other than the cooling problem, the picture quality and the monitor itself was great. Decided to splurge on an expensive OLED monitor for work, but I bought myself a problem instead.

Almost Perfect

The monitor is amazing, but two huge issues I have with it is you pay a super high price, and it doesn't even feature a 240 Hz Refresh rate.(The reason for this is due to people maybe not having GPU's that support DisplayPort 2.1, so they went with 165 Hz as it's easier to drive, but if you're buying this you most likely do.) The other thing is that the AI Upscaling only works with 60 Hz it would be an epic monitor if you could go into dual mode while it's at 330 Hz and use the AI upscaling for the image to get that crisp 5k2k resolution.(Maybe a firmware update at some point?) That in itself would make the price worth it. As I see it right now it's an amazing monitor probably the best ultrawide at the moment, but I'd wait for a sale.

Really, really great monitor. Plug and play!

[This review was collected as part of a promotion.] This monitor has really beaten my expectations. I have needed something that could handle color-accurate video editing during the day and high refresh rate gaming at night, and this hits the sweet spot. A few things I noticed: Colors: Vibrant right out of the box, didn't have to spend hours calibrating. Build: The bezels are super thin so it looks really clean on the desk. The stand is also heavy-duty. My old monitor used to shake when I typed, but this one is rock solid. Setup: Basically plug and play. Took me less than 5 minutes from box open to using it! Overall, if you are a hybrid user looking to downsize to just one really good screen, this is totally worth it. Review submitted as part of a program that provides a purchase discount.

Love it!

[This review was collected as part of a promotion.] I've been using the 39” UltraGear evo GX9 for a little while now and it honestly feels like such a big upgrade. The screen is huge and super immersive, especially for gaming, and the OLED makes everything look so crisp, colors really pop and the blacks are insanely deep. It also feels really smooth during gameplay, which I noticed right away. i like that it's not just for gaming too—I've used the smart apps on it when I just want to chill, which is a nice bonus. Overall, it just feels like a really premium, well-rounded monitor that makes everything look better. Review submitted as part of a program that provides a purchase discount.

Better than expected ZERO Regrets!!!

This monitor is absolutely incredible!!! I've never felt such immersion in a game outside VR. The picture on this monitor is perfect the colors, the brightness, everything is phenomenal! Text sucks because of the PPI but I knew that going in and was fine with that because I bought this strictly for gaming, and media viewing. But honestly while I wouldn't want to go read an ebook on it, the text really isn't that bad and doesn't bother me. I have zero issues reading anything on windows, or website scrolling. I highly recommend this item. Especially like me if your mostly using it for gaming, and media consumption. While 4k would look better I'd rather have the 240hz refresh rate. I haven't messed with WebOS features but from what I can tell it looks easy to navigate and understand. Only negative is it went down $200 the day after I ordered it but I suppose it happens.

An Awesome Product!

[This review was collected as part of a promotion.] In my first few days of using this monitor, I have been nothing but impressed so far. I game a lot and also consume media content and the OLED panel and size is truly immersive. This monitor is the sweet point of not being overwhelming big, but still looking massive. I could not recommend this product anymore! Review submitted as part of a program that provides a purchase discount.
