Review Image by Lirim Doda
So, after using this monitor for a few months now, I feel like it's a good time to post a review for others who may be considering this specific model. This monitor was a huge upgrade for me, price wise and feature wise. The 240 HZ at 1440P is beautiful, and my graphics card sends its regards. I don't think I can ever go back to normal 1080P. The quality is very nice and precise, the 240hz especially while gaming is insane. I play games like Valorant, CS, LoL, etc. and the difference is VERY noticeable. I come from 1080p 144hz, and before that it was 1080p 60hz. This monitor also has HDR and G-Sync support, which is pretty nice. I personally don't like using HDR, but I have tested it with this monitor and it works pretty good. HDR in general on Win 11 is kinda shoddy in my opinion, so I just don't use it. It took some getting used to for sure, but the menus are good and have a lot of options. There is an app you can download to control the settings if you don't wanna do it manually, but I didn't like the app and I prefer to set my preferred settings on the monitor itself. With my next PC build, I plan on doing everything ROG Strix to match the monitor. This monitor comes with it's own power brick, which makes sense, but I think because of this there is a technicality with the monitor. When the monitor is turned on, then the output to your computer is on, and vice versa. So basically, if you're using your computer or you wanna leave it running at night, when you turn off the monitor your computer will no longer be receiving input, so in a sense the monitor gets "unplugged" and if you have a second monitor that one will become the main monitor while this one is off. It's a little weird, but I've gotten used to it. My previous old monitors never did this, so I feel it's important to mention here since when I was setting this monitor up for the first time, I thought it was broken haha. So now what I do is: I lock my computer for the night or turn it off, and I just leave the monitor on while the screen times out after 60 seconds. So the monitor technically stays on and doesn't mess with the input, and it also leaves the RGB on the back of the monitor on so it's some nice ambient light which gives me comfort personally. Overall, I can't really find anything negative to say about this monitor. Perhaps the price is a bit much, but if you can afford it, then it's a great investment. This is the kind of monitor I used to dream about having when I was in my teenage years gaming on a low tier PC. Now that I'm older and have the means, this purchase was 100% worth it for me and honestly was one of the best purchases I've made in 2024. You can never go wrong with ASUS in my opinion, they are top tier and it's for a reason. I don't really ever write product reviews, but this one deserves a good rating. ... show more

    • High quality, high refresh, low response, perfect for gaming
Style: 27" Fast IPS QHD 270 Hz G-SYNC USB-C
Great 1440p quality with a bright panel, very fast response time, makes gaming a charm compared to my previous 1080p 144hz monitor. It's very convenient being able to adjust both the viewing angle and the height of the monitor, so I was able to line the screen up perfectly with my smaller second monitor. I think the RGB logo backlight is a bit unnecessary and I'm not a fan of the button setup, especially the power button being on the back. But got this monitor on a great deal and it has exceeded my expectations. ... show more

    • Nice Birghtness
Style: 27" Fast IPS QHD 270 Hz G-SYNC USB-C
Excellent product and it's almost perfect just because it has a slight brownish tint in the blacks, but that's forgivable because it has excellent brightness and colors. I didn't want to buy an OLED because I don't want to worry about the monitor's health in terms of burn-in, and that's why I bought this monitor. ... show more

    • Damaged and missing parts.
Style: 27" Fast IPS QHD 270 Hz G-SYNC USB-C
The box arrived in good condition. When I unboxed the monitor the Power Adapter was missing. I called and a week later the missing power adapter arrived. I plugged in the monitor, only so see there are 3 dead spaces in the middle of the display. To me it looks like someone's fingernails dragged on the monitor surface below the plastic screen. Requested ASUS to call me back. No response. I had to call them 2 days later. They asked me to take a photo of the damage. I do not have a digital camera or a camera on my phone. So, now I am being told someone will have to call me back in the next day or two. Unacceptable, and if I do not have my callback I will just do a chargeback. Quality control and customer service at ASUS is NOT what it used to be. ... show more

Sin problemas de flickering. Excelente tasa de refresco muy buena calidad de imagen y 27in 1440p es justo lo que andaba buscando. El problema es que no puedo ponerlo a 270Hz pues tiende a dar problemas en juegos y sistema.
