    • Great picture, mediocre stand
Size: 27-inch Style: WQHD 180Hz
This looks amazing for the price I paid. Only con: The stand kind of sucks, it flexes a ton so the monitor wiggles if your desk moves at all. But I’m still very happy with the picture. Sound is passable, probably better than a laptop, and what I expected out of built-in monitor speakers. But hopefully you aren’t buying this for the speakers… ... show more

nice monitor! was my first one with a high refresh rate so the difference was extremely noticeable and great. the built in speakers are a nice little bonus despite the mediocre quality because it means I dont need to hook up any speakers if I dont want to wear a headset. HDR supported and whatnot, nice color display, and smooth frames :) stand feels cheap but does the job ... show more

    • Amazing Monitor! The Stand? Not So Much.
Size: 27-inch Style: WQHD 180Hz
This monitor works great and getting it on sale made it even better. 1440p is all you will ever need especially for console gaming. It runs up to 180hz on display port but hdmi it can reach 120hz easily allowing you to maximize your response time for your console and give yourself more time to react. You can quickly switch between different modes for different games and even create user specific modes that you can adjust to your hearts desire. All of the display settings are easily adjustable through the analog button on the rear of the monitor. Also the monitor has settings that can actively adjust your picture for different situations in games (I currently cannot recall the term for it). You can adjust the brightness, saturation, and more. One of my favorite features is the different display presets such as low blue light that can help when working late on the monitor. My only demerit of the monitor is the stand itself is kind of flimsy and is not adjustable. I would advise getting a mount for your monitor of some sort if you are to purchase this monitor. Otherwise this is an amazing monitor I got for an amazing price during Prime Day Deals. ... show more

    • Great product. Better service
Size: 27-inch Style: WQHD 180Hz
I bought two of these monitors at the end of 2025 and was really living them. Crisp colors, very responsive all around great. Then one of them broke. Less than three months and the screen was full of white lines. But I'm still eating these monitors five stars. Because Acer has the BEST customer service I've ever dealt with. The phone call was fast, I wasn't kept on hold long and within two days the monitor was back in their have. Ten days later it was back and working perfectly. No fuss, no hassle and no charge. This is how you keep a customer. ... show more

This is a review after 3 months of usage, spoiler alert, I’m pretty happy with it.* I bought this 27inch 1440p 180Hz (KG271U N3bmiipx) monitor for around 170 usd with offer and taxes. Pros: 1. 2K, very fast 180hz refresh rate, with built in speakers for 170 USD. 2. Pretty high color range (DCI-P3 95%), not verified, but to naked eye, love the vivid colour accurate display, this was important to me. 3. IPS screen, meaning good viewing angles, also important for good viewing experience. 4. Decent HDR for an IPS LCD budget monitor. 5. Didn't notice any flickering. Reasons for asterisk: 1. In standard or other modes, even when set to 100, brightness feels low in well lit environments. Turning HDR mode on solves this issue, probably because of increased peak brightness, but this makes it too bright in dark environments, you won't be able to adjust screen brightness in HDR mode. Switching between standard and HDR mode felt a little tedious. 2. Overshooting is noticeable to naked eye if overdrive setting is set as extreme. Recommend setting it to minimum, or off, then it’s not at all noticeable. 3. Speakers are like what you’d expect in your typical gaming monitors. Pretty mediocre, will get the job done. They lack any base or instrument clarity or separation. In movies or songs, vocals are pretty crisp, but the background music sounds pretty low. Could be solved with headphones or speakers. 4. HDMI connections only supports upto 144hz. 5. Lack of height adjustment for stand. 6. Felt like a thick monitor, build quality is decent, all plastic, does not give you premium feels, but good for it's price. At this point you might be thinking, why did this guy give 5 stars when the cons list is bigger than pros. It's because I compared this with similarly priced Sansui ESA-G27F6Q and Arzopa M1RC side by side, and overall Acer seemed like the best pick in this price range. ... show more

    • Good 1440p monitor
Size: 27-inch Style: WQHD 180Hz
It’s a nice 1440p monitor. It has variable refresh rate, and multiple different settings to adjust color, brightness, and other picture quality things. It also goes together easily and is a good size for the resolution. The only drawback is that it’s an IPS panel and isn’t 100% RGB or whatever, so you aren’t getting the craziest color experiences, but it functions fairly well as is. I would recommend for the price. ... show more
