    Great value for the money

    To be honest, the biggest impression I have of this monitor is that “I can’t go back to anything else.”The first time I turned on the OLED, the black levels and color reproduction were in a completely different league compared to a standard LCD. It’s especially noticeable when gaming, particularly in HDR scenes—it’s truly breathtaking.I mainly use it for PS5 and PC gaming, and the 4K + high refresh rate experience is incredibly smooth. Input lag is very low, making FPS games feel incredibly responsive.The only thing that concerns me is the risk of OLED burn-in, so I now have the taskbar set to

    A great display if you know what you're looking for

    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

    Amazing

    The best picture I have ever seen on a display! So much cheaper than a GPU upgrade.

    A great Gaming Monitor unless you want to hear the game sound to match the graphics

    Display is second to none at 32" and sparkling graphics BUT I was pretty disappointed in the quality of the sound coming out of this Monitor. It's a GAMING monitor for God's sake and the sound is squarely in the "wimpy" camp. It also keeps trying to muscle back in when I have switched to KEF bluetooth Egg speakers never to look back. They are awesome sounding but this display needs to step up their game to match the games they want you to play on screen

    Great quality, as advertised, LG has amazing packaging team

    As advertised looks great. Set up was simple. Built well. I have no complaints with the product. And LG does an amazing job packing there products. On the other hand, Amazon whoever packages the items to be shipped doesn't really seem to care about there job they just put the item in the much larger box and shipped it no padding or bubble wrap. But die to LG amazing packaging department the product made it here safely and in great shape so I have nothing to complain about.Edit I have had it for about a week or so and it runs beautifully. One of the most gorgeous monitors I have ever owned. The

    good image, broken firmware (won't wake up)

    For nearly a grand, it's... fine. I would expect it to have been just a bit brighter. Not very many controls on it, even with the app. Easy to switch between the 240 and 480 hz operation with a button, but you have to remember to set it where you want it *before* you start the game, otherwise it get's confused and will likely mess up your settings. The image is good, no screen tearing or ghosting or anything, though games can still feel stuttery depending on your system and (more importantly) the coding for it.Now here's my real gripe. IT TAKES FOREVER TO WAKE UP. Half the time, I have to turn

    Perfect gaming monitor. Wished they also came in TV sizes

    Best display I've ever owned. I wish LG made this exact display feature set in 65 - 80 inch screens for TV viewing. Switching between the 4k at 240hz and 1080p at 480hz is seemless, even when using a Linux OS like Bazzite. By the way, if using something like Bazzite, I recommend keeping VRR off, as some older games through proton will bug out and flicker when launched. Also, be sure to run the Image Cleaning function first, and a few times after manually to get the best picture. After that, it should be automatic anytime the display goes to sleep to image clean. This is my first OLED, and it's

    The 4K OLED of my dreams!

    - Color accuracy: Respectable, great even. Slightly off compared to my production grade monitor, but just as they were advertised! Bravo!- Peak nits: Fantastic, these are the best nits. Everybody knows it.- Refresh rates: So fast you can't even see them. (240hz@4K - 480@1080p - SILKY SMOOTH!!!)- Response time: Not haunted. No ghosts here.- Pixels: There's a lot of them, trust me. Kept losing count otherwise I'd tell you.- Features: One firmware update away from perfection.Pictured is the difference between an LG 27GN950 (left, a 4K edge-lit IPS) and this monitor (right, a 4K MLA OLED).
