    • Absolutely Amazing Monitor – Zero Issues
Style: 27" OLED QHD 360Hz
I couldn’t be happier with this monitor. The ASUS ROG Strix 26.5” 1440P QD-OLED (XG27ACDNG) has been flawless so far. The picture quality is incredible — colors are vibrant, blacks are truly deep thanks to the QD-OLED panel, and everything looks insanely sharp at 2560x1440. The 360Hz refresh rate makes a huge difference in competitive games. Motion is buttery smooth, and input feels extremely responsive. Whether I’m gaming or just browsing, everything looks and feels premium. Setup was easy, the build quality feels solid, and I’ve had zero issues with dead pixels, flickering, or any other problems. It just works perfectly. If you’re looking for a high-end 1440p gaming monitor, this one is absolutely worth it. Highly recommend. ... show more

    • One of the best monitors on the market
Style: 27" OLED QHD 360Hz
Ridiculously high quality OLED with great color accuracy, amazing anti flickering tech and surprising brightness. Very good but high priced which makes sense as OLED is very complex to make. Gaming oriented but is great at work tasks too. Honestly 360hz is a perfect refresh rate you likely won't ever need much more than that unless your a top level E-sports player. 1440p also means it hits that sweet spot of high performance and amazing quality so it is the perfect middle ground. One of the best monitors you can buy period. ... show more

    • Great OLED monitor that will serve me for many years
Style: 27" OLED QHD 360Hz
Things I liked -360 Hz, moving the mouse cursor at desktop is silky smooth. No latency delay at all. When playing games, there is no ghosting or anything. -Value, I got this monitor on sale for $629 + tax. Great price for an semi-glossy monitor. I left the plastic coating sheet on the screen and it still looks great. -Built in FPS counter. I use this feature all the time to check what fps am i getting when playing games. Easier than using 3rd party software. -Able to plug in external pc speakers in the headset 3.5 jack and output sound. Perfect if you want to play console gaming on the monitor if on a budget. -Only took me probably 30 mins to set up and it worked fine. I never updated the firmware either. -Brightness is fine. I use the HDR when applicable for games. You have to manually turn on the HDR settings in windows before going into the games. Then you need to turn it off when you done using HDR. SDR colors looks better at desktop than HDR. Things I didn't like. -Can't raise the screen that high, but the monitor is at face level so I quickly got used to it. -Pixel cleaning reminder pop up is a hassle. It kills my immersion when I'm watching movie or playing game and it pops up. You can turn it off but I just do the 5 mins pixel cleaning every 8 hours so I don't risk or delaying getting burn in. So far no burn in after 3 months. Be sure to register your monitor to get the 3 year OLED burn in warranty. -Some old games won't display on this monitor like Resident Evil HD remaster that I noticed. Be sure to have an old monitor handy if you run into some problems. ... show more

    • Best 360hz oled
Style: 27" OLED QHD 360Hz
I've been using this monitor for a few months now; it's the fastest and most beautiful monitor I have ever owned. The colors are amazing out of the box, playing games and watching content looks stunning with 1440p, vibrant colors, and customizable settings it offers. The 360 hz and 0.03ms response time makes fps games very smooth with no ghosting or lag. The monitor has oled care features others don't offer to keep the monitor lasting longer and an efficient custom heatsink along with the 3-year warranty. It's also G-sync and FreeSync compatible so you don't have to worry about having the right GPU. This monitor is worth getting if you're looking for a premium monitor around this price range. ... show more

    • One of the Best 1440p QD OLEDs
Style: 27" OLED QHD 360Hz
Great monitor, bought this one time before but I wanted to try 4K out so I purchased two other variants, the 27inch 4K and 32inch 4K to see how they looked. Long story short I scaled back down to 1440p, to this monitor. The QD OLED panel and 360 Hz refresh rate makes an excellent gaming experience.

    • Great monitor
Style: 27" OLED QHD 360Hz
Perfect, just perfect. There is no flickering or anything. The size is just right for gaming as well. The quality is AMAZING, I seriously cannot go back to my IPS Panel monitor now, good interface and it comes with a warranty that expires in 2029!!! It is a bit pricey but I think it’s worth the price. My only issue has been screen tearing, but that’s not really the monitors fault. It also comes with several bags and stickers, this is a premium item from a premium brand, it’s definitely what I’d pick for others if comfort was their only filter ... show more

    • Came broken.
Style: 27" OLED QHD 360Hz
Screen would turn on for a second then turn off. After messing with it for two hours and contacting Asus support they told me it was a hardware issue. . Sent back and got an Msi one that’s 500hz from Newegg.

I’m coming from a 170 Hz 1440p IPS, and the difference is insane. There’s absolutely no overshoot, the response time is so good it feels like the mouse moves before I even start thinking about the movement. It took me a bit to get used to it, but I ended up setting new records in my Aim Lab playlist, honestly. History games are great too, even tough i'm getting the same fps it feels more fluid, i guess is because of the instant pixel transition, but rdr2 looks and feels great. The blacks are truly black too, it does not really show well in photos, but is really amazing, pixel density is good too, one thing i don't like that much is text clarity, but you get used to it pretty fast, and if it really bothers you too much there are work arrounds for it. ... show more
