Very happy with it
So I use oled for primarily console gaming (Xbox series x) only. I previously had the 27gs95qe, this is a step up, I’ve noticed better hdr brightness, and finally lg unlocked the black stabilizer in hdr mode, (on the older 27gs model it was locked out), and can also have a personalized picture mode too, although I’m running it at 4k 120 (Xbox downscales it), I’m happy with the performance, motion clarity colors and brightness, text clarity is decent. Overall can’t beat oled for gaming. Also matte coating does a great job in bright rooms keeping blacks dark and inky.

Absolutely Blown Away – Perfect for Xbox Series X and More!
I am beyond impressed with this monitor. It has exceeded any and all expectations I could have ever had, and works amazingly with my Xbox Series X console. The ultra-smooth, tear-free gameplay at up to 480Hz refresh rate is something you need to experience for yourself. I’ve attached a screenshot of the settings menu showing the capabilities the console recognizes, which proves just how well the monitor integrates.When I first received the monitor, there were some imperfections, including lines on the display, and a stuck pixel. However, the built-in “OLED Image Cleaning” feature that runs every time you turn off the monitor worked its magic and completely self-healed the screen. This is something I had never seen before in a monitor, and it’s absolutely a game-changer!I did reach out to LG Support, and they were incredibly responsive. They reassured me that if the self-healing didn’t fully resolve the issue, I should reach back out. Thankfully, the issue was fully taken care of.While 480Hz at 1440p is impressive, the monitor also performs very well at 4K 60Hz in my testing, which was a nice surprise. The monitor comes with a stand, but I mounted it on a VESA stand, which was super easy to do. Initially, I couldn’t find screws for the mount, but I later discovered they were already pre-installed on the monitor itself.As for the RGB lighting on the back, I opted to turn it off, but it’s a neat touch for anyone who enjoys that feature.This OLED monitor is truly next-gen, offering unbeatable speed, stunning clarity, and an overall incredible experience whether you’re gaming or watching content. Highly recommend!

Super fast display – amazing game play
The monitors super fast display image brings my gaming to the next level. Every intricate detail is immediate and response has no visible lag. Motion clarity is amazing. My PC and PS5Pro never looked this good. HDR color is spot on.The design of the monitor is very sleek and understated in charcoal gray. The edge to edge display avoids distraction with a minimal bezel edge. The narrow bottom chin doesn’t interfere with the image. The RGB lighting on the back accentuates the screen and looks cool as I like to play in the dark. The brightness and color selection is good. You can turn it off if you wish. The monitor has an overall stealthy look. The build quality is excellent as well.The monitor stand is fully adjustable and take up minimal space on my desk. It allows adjustment in every direction to get the perfect viewing height and angle.I used to the image presets to save the fine tuned setting for either my PC or PS5Pro. The settings are easy to access and fine tune. The amazing motion clarity is as good as a still image. The matt screen has excellent brightness. The contrast levels are exceptional too. The overall immersive image made my game playing amazing. I really like this monitor.Though it is expensive, based on the features and performance I find it to be a good value for the money and well worth it.

Never had anything as nice as this monitor!
It feels almost criminal that I’m only using this monitor for Sims 4, but it just looks so good with bright colors and god is the picture smooth as silk! I’ve never had anything this nice before! Mine came perfectly out of the box and setup was easy practically just plug and play. I’m seriously babying this monitor and I’m not the most technically savvy to give a whole bunch of specs but as an OLED monitor the color and depth to the picture and colors are amazing! The refresh rate makes it so that every frame flows smoothly.

Incredible for gaming
I’ve been using this for about a week, and it’s a dream for gamers. The 480Hz refresh rate is no joke – everything feels buttery smooth, especially in fast-paced shooters. The OLED panel delivers stunning colors and deep blacks that make every game look cinematic. I have been absolutely enjoying Black Myth Wukong and Marvel Rivals.The setup was super easy, and it looks sleek on my desk. The inclusion of DisplayPort 2.1 and HDMI 2.1 means it works great with my gaming PC and next-gen console.That said, it’s not perfect. The brightness isn’t the best in a super bright room. But for gaming? Absolute perfection. If you’re serious about competitive play, this monitor is worth it.Overall, this is hands down one of the best gaming monitors out there. If you’re looking for the ultimate gaming experience, this is it. Highly recommend!
