    • Nice Monitor
Size: 27 inches Style: 27GX704A-B
Very good display. Clarity, good color, nice brightness. Default settings are adequate with some fine tuning. If your first OLED monitor you'll want to look into the settings for black levels and black saturation. Adjust to your preference. There are two settings. Black Level and Black Stabilizer. All other settings are much like any other monitor besides those intended for OLED care. Of which there are a few of them. I find picture quality to be very good across all applications and media. Games look amazing. So far as movies, streaming, etc? Outstanding with one caveat. And that is you're still at the mercy of the source material, stream quality, output resolution, etc. A OLED display is like putting on a pair of glasses. You'll see better so to speak, but if what you're looking at is low quality, glasses aren't going to fix it. In fact you may see its flaws even more so. So keep that in mind when viewing video content with this monitor. Yes it could look bad. Because it might be bad. OLED won't fix poor streaming quality, video compression, low resolution. It'll just light it up better. Adjust your display as needed in such cases. And when consuming media remember this is a monitor, not a television. It has no fancy image processing hardware, Dolby Vision, self adjusting this and that. Its a simple panel, looks great, and is basic all around. No built in WiFi, apps, its not a "Smart" anything. That is where YOUR components come in. Computer hardware, gaming console, streaming device/services, internet connection. If those are in order and optimized, so will the monitor be. So far as visual enhancements this has HDR. Thats it. I don't use HDR so can't comment, however. Oh...and browsing the internet, social media, etc, is just as well as with any other monitor. It sure is smooth, though. So far as gaming, its great. Responsive, fast, vibrant. You'll want to adjust your component and game settings anew, and get familiar with the Black Stabilizer. Which reduces or increases black saturation for games. But other than that its a very straightforward task to get the most out of this unit. The stand is "fine" and hunkered down with a weighty anti slip metal base. Its adjustability is good, and movement well damped. If coming from a high quality Mini LED ISP or VA panel, you may not appreciate this upgrade as much. OLED doesn't reinvent the wheel after all, its simply a better mousetrap. Its a computer monitor at the end of the day. Is it worth its price tag here in early 2026? Well...my outgoing Dell was purchased just four months ago. Very basic 1080p, ISP budget monitor. I donated that to a place in need. Not because I didn't like it, I did. A lot. But it had to go. So when replacing it I thought "why not?" And so I got this. As of this writing the LG here cost me $315 more than my Dell did. And tbh I consider that a bit of a bargain, and worth every penny. Just based on my brief experience I see no reason not to have an OLED monitor as my primary from here on in. It is impressive, and LG has done a good job here. ... show more

    • Awesome monitor
Size: 27 inches Style: 27GX704A-B
This monitor is fantastic. I went from an aging Nixeus 27" 1440p IPS LCD to an MSI MAG 27" OLED that broke within 6 hours, to this monitor, and am very happy with it. At under $500, it's a solid price given the feature list. The response times (input lag) are fantastic, and it supports 240hz adaptive refresh rate with both Gsync and Freesync. It's got HDMI and Displayport connectivity. And, it's an OLED monitor. Being an OLED means the color reproduction is fantastic and damn near 100%, so coming from an LCD you'll notice a huge boost to color contrast. Blacks will be black, not dark gray, and colors will be accurate, allowing you to notice subtle color gradients and other details you wouldn't notice before. The monitor is easy to use, with a single control knob on the underside that allows you to both turn off the monitor and go into the settings. You can change things like brightness and picture mode, as well as "peak brightness" which impacts the max brightness your screen can hit in localized spots during HDR content. Overall, works great. I will say the colors don't quite pop out as much as on the MSI MAG QD-OLED, but it's also more color accurate and easier on the eyes. Trying to read anything on the MSI had my eyes watering and they felt like they were being poked, so I guess it's sort of a gift that I had to return it and get the LG. ... show more

    • Amazing monitor
Size: 27 inches Style: 27GX704A-B
I got this monitor for around 440$, for this value its absolutely amazing. Of course OLED looks fantastic but its also really smooth and has great colors. The refresh rate at this price is pretty good and the size for me works best, I've tried bigger monitors and for competitive gaming this size works way better for me so I'm not overly looking for the corners of HUD's. The menu has all the options you'd expect also and it gets plenty bright for me. Cant speak on the stand as I immediately mounted it on a desk mount. It incredibly thin, like... wayyy too thin, its super cool, but sometimes I feel like I'm gonna snap it in half moving it closer or further away. I don't think it would actually break like that just what it feels like so no big deal. ... show more

    • Gorgeous Screen - Major Upgrade
Size: 27 inches Style: 27GX704A-B
This really is a top notch screen and worth the money for me if you catch it on sale, or not if you have the budget. Colors are amazing. I'm really glad I went with the glossy OLED too. Reflections aren't an issue for me and I have a light behind me and over me. This really shines on Gray Zone Warfare and Squad. I went from a 32" 1440p ips to this at 27" and I dont miss the extra space. It's gorgeous. ... show more

Let me start off with this first this was my first Oled monitor, so I was skeptical burn in I've heard etc it gets hot etc. I plug it in the screen never gets hot unlike my lcd both 1440p. The screen is full of color the sound is good if you have speakers , though I'd suggest you get longer cords if you have a sound bar. It's been a few months I'm loving this purchase even watching movies looks amazing with the juicy colors , I don't think I'd ever choice to go back to LED ! I definitely recommend you buy this, LG has always been high quality and this monitor is no different! ... show more

    • Great monitor, bad software
Size: 27 inches Style: 27GX704A-B
This is a very well-built monitor with amazing picture and color quality. Seriously the picture looks incredible from ANY viewing angle. There are tons of settings for the display for comfort and picture adjustments, and you can configure the software to change the monitor settings based on what program is running. This leads into the negative - the software is just badly made. There is an on-screen popup every time you start your computer that has to be manually closed. Also, the app causes pretty heavy input lag on your computer any time you're switching apps, and sometimes it lasts 10-15 seconds where the computer is not responsive. The software is not necessary - you can manually adjust things from the buttons on the monitor itself, but it would be nice if they fixed the problems with the software. ... show more

    • An amazing monitor but.....
Size: 27 inches Style: 27GX704A-B
Review Image by SP Tech
I had this a month ago, and with a total of 230 hours, it's been the best upgrade I've ever made.... The quality is good, the sharpness is better compared to my other 1440p monitor, and the colors are great but it needs a proper setup to get the HDR and colors like those shown on display. The Hz are excellent for competitive games like COD, Fortnite, CSGO, or any game that requires precision. For Xbox and PlayStation players: Deactivate the standby option in the monitor settings, which prevents the monitor from waking up when turning on any console. ... show more

This is definitely the best affordable gaming monitor you can buy. High-quality building with a perfect screen that blew my mind the first time I saw it.
