Best monitor I’ve used
The 480 hz 1440p oled is really good for its price, there is so many points I want to make though. In gaming it’s 480hz obviously but I think it’s better than 540hz TN or IPS panels because the oled panel makes it more natural and there is WAYY less ghosting than the other panels I’ve come across. The other point I wanted to make is that you need a really powerful gpu to run it without stuttering which is ideally something equivalent to an RTX 5080 which I use with a ryzen 7 9800x3d and also 32gb ddr5 ram. I don’t know if this is with all oled panels but sometimes I do get flickering and I did my research and found out that it is VRR (variable refresh rate) which causes the flickering. Now my monitor doesn’t do that I’m guessing this because I turned off hardware acceleration and instantly it stopped flickering. Also the way this monitor works is really good in games like valorant or Fortnite and even Black ops 6 because i play 2560x1440 on low-medium settings with DLSS on gets me about 500-570fps. The monitors stand I’m a really big fan of because it does not take too much space which is a good thing about this monitor. As a £750 monitor (I bought it for £650) it is still really reasonable for its price and because I’m a very competitive gamer this is truly the best monitor I have ever played on. I moved from 360hz TN panel to this. This monitor is also good for content creators or people that edit pictures or videos which really gives you the colour accuracy since oled is the most natural panel and it’s best known for colour accuracy at the end of the day. One thing I wouldn’t advise is if you want this monitor for office work or just typing emails and stuff then I would recommend a different monitor since this monitor is mostly for gamers and people that have things to do with content creation or just creation in general. This monitor also has oled image cleaning which basically prevents your panel from getting burn in. Also please if you have read this long review put a fully black wallpaper in windows and also auto hide your taskbar to prevent burn-in. Thanks so much for reading this and if you buy this monitor, enjoy it to the fullest

Best screen ever
An amazing monitor. LG panels are the best. This OLED is crystal clear with dark blacks. Was a bit fiddly to set up due to all the different settings but once done it’s stunning. Is an aggressive curve however it hits your line of sight perfectly. Great for productivity and fantastic gaming to boot

A great, responsive OLED, but update the firmware and settings
I chose this LG UltraGear as my new main monitor, specifically opting for a WOLED panel over a QD-OLED. My desk is next to a large window, so I wanted a monitor with a matte screen that could handle reflections well for both work during the day and gaming at night, and this has been the perfect choice for that scenario. Coming from what was a fairly high-end IPS display when it released, the leap to OLED is staggering. It is a huge improvement in every single regard: the colours are significantly richer, the inky blacks are truly perfect, and the responsiveness is on another level. For gaming, this monitor is simply impressive. The incredible refresh rate makes competitive games feel exceptionally fluid, while the perfect contrast ratio is a game-changer for darker, atmospheric horror games. The experience extends to media, too. Watching HDR Blu-rays on this display is a treat; the visuals are so impressive that they even surpass my main TV. The inclusion of DisplayPort 2.1 is also a great touch for future-proofing. However, it's important to address the software. Many of the reported launch issues, like the poor 60Hz responsiveness, have been fixed via firmware updates and hopefully more improvements will come in the future. The update process is easy enough, though the PC application you use feels clunky and has some poor translations. More importantly, I would strongly recommend new owners dive into the settings immediately. The default picture mode has an adaptive brightness that can make the screen unreadably dim at random moments. Switching to a different mode and making a few tweaks makes a world of difference.

Disappointing beyond words.
By far the worst monitor I’ve ever tried. I have an ASUS Zepherus G16 which comes with a 240hz 16inch Oled monitor as standard and this blows the LG monitor out the water. Not only is the picture clarity awful, but the colours appear grey and lifeless regardless of how much you tweak the settings. The grainy and dull image is as bad as the reviews state. I took a risk ordering this instead of other highly recommended monitors and it certainly backfired. Please, if you’re on the fence about this monitor, look elsewhere and save yourself the time and effort.

Fantastic!
As of now this is a 5 star rating. I have only had it around a week. I have no greyscale banding, text is perfectly readable and the semi matte coating does not seem to effect picture quality. The colours are insane and really pop, the blacks are...well...black. I have a black background and when im not using it i cannot tell its even on. The brightness is insane also, i used to use 80% on my old IPS monitor and i have had to lower this down to 55%. The motion clarity is fantastic i was testing various frame rates and at 60 fps with g sync it felt like 100 fps due to the pixel transitions and response times. Either i won panel lottery or the reason it was out of stock for so long is because they fixed some issues. But i am one happy first time OLED user. I did tons of research before purchasing this, so i knew what to expect and what defects ect to look out for and this really has amped up my experience when gaming. I only use this monitor to game, all my desktop icons and web browsing ect are done on my secondary monitor, if im not using it them the screen is just black.
