    • Perfect for my needs, some questionable reviews
Style: 27" black
There are some questionable reviews on this monitor. I’ve been using this monitor since early February. The only downside is even though it’s listed at dp 2.1 but it isn’t the full speed, requiring you to run it with DSC, which honestly hasn’t been an issue for me so far. People are saying the brightness is too low and I disagree completely. I’m willing to bet they didn’t know about the peak brightness increase in the settings. This panel gets extremely bright and rivals the brightness of my lg c1 OLED at high peak brightness in hdr. Also someone mentioned a lack of panel care settings and I also disagree, as there are 4 different pixel shifting modes to choose from, panel cleaning when in sleep, and dimming when displaying static content for long periods of time. Someone also mentioned not being able to tell if the monitor was asleep due to no front light, but there is an led ambient light on the back is you choose to enable it that serves the exact purpose they’re complaining about. If you can catch this monitor for $100+ off, it’s an insanely good panel. Impeccable response times, 480hz, bright hdr, amazing black levels, great build quality and stand, there’s not much more I could ask for in a display. I’ve been enjoying games old and new on this panel at extremely high frame rates and I can never go back. 480hz feels like looking through a window, the motion clarity is something you have to see in person ... show more

    • Best 1440p oled right now
Style: 27" black
This monitor is incredible. Smooth as butter gameplay. Deep blacks. Auto screen clean when I’m done on the pc for the day and it detects no input. Premium as can be with metal stand and design. Came packaged great. The image clarity is phenomenal. I’ve had asus oleds and other asus ips, and friends that have Alienware QD-oleds. This thing has the best picture I’ve seen in an oled and the text clarity is great. I 100% recommend this monitor. I was going to write off oled monitor tech and stick with ips and mini led but this monitor changed my mind. I have a LG C3 as well and I believe Lg just makes the best oleds. The height adjust is perfect I don’t need a monitor stand anymore as this can raise very high. The ambient lighting on the back is a nice touch. I’ve gone through two other asus monitors trying to find the right for me and decided on this. No regrets and I’m sure you won’t either. ... show more

    • OPENED BOX SOLD NEW. LG DEALERSHIP NIGHTMARE. 30 DAY RETURN PROCESS.
Style: 27" black
By far the worst experience ever ordering a display from Amazon. WARNING! This doesn’t come from LG directly. Instead, an LG certified dealer will ship your expensive display in a refurbished box that’s opened. Good luck returning the item. There is a reason why this product is marked as frequently returned. I purchased this a month ago and still waiting for my refund. Amazon is experiencing significant delays in processing returns so be ready to wait 30 days for your return to process. I regret this purchase more than anything! I would’ve avoided all of this had I read the reviewers. I trusted LG and didn’t feel the need to investigate the product. Don’t fail like I! Please do your research and stop ordering from Amazon. Otherwise, they will continue to take us customers for granted. Imagine if we all stopped ordering this product? Amazon would have no choice but to act and make it right to us customers. They can care less for the customers experience as long as the money keeps flowing. ... show more

    • The epitome of monitor technology
Style: 27" black
The epitome of monitor technology. It's the perfect monitor guys. The blacks, the colors, the motion clarity, the 0 ghosting. Just wow. How does it get any better than this? OLED first timer here so. 480Hz is noticable, the smoothness. Maybe hardly noticable from a 360Hz but still counts. Colors might look a bit weird on default color settings, has a red tint. But once you change to 50 Red, 58 Green 58 Blue it's just perfect. I also keep my hues on 60 as well so the colors pop. You will never go back from OLED. I tried really hard to find out why this 'matte' coating is bad as people out there say but there is just no way. Okay maybe QD OLED might have 5% better colors and contrast it wouldn't really make a difference for me. The ASUS 480Hz or this or Sony one it's all the same thing. Just get the best deal out of them. For some a 240Hz OLED may be enough. But 480Hz just looks stunning for me. It's really personal preference to be able to notice such detail. ... show more

    • LG cooked with some heat here.
Style: 27" black
Bright even at 50% in SDR, VIVID oled my panel did not have weird dirty whites like some claim upon setup but I also recommend color calibration these colors are very nice in HDR. Great monitor heavier than I was expecting panel settings in windows claim it can do 4k as well, have not tried that 1440p is why I bought the panel. Extremely fast response out of the box. ... show more

Why did you pick this product vs others?: Just purchased and received this product. I picked LG because I've always enjoyed their OLED screens but this one out of the box could not display right side of the screen. Completed factory reset which fixed the issue momentarily but defaulted to this issue. Changed HDMI input, changed cable, changed HDMI source (computer & PS5), changed power outlet monitor plugged into. Also, brightness on this panel is strikingly subpar despite vivid colors. Unfortunate and wish I wasn't returning this product. ... show more
