Great picture, mediocre stand
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…

Love it with an asterisk
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.

Great product. Better service
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.

Sometimes I work, sometimes I play – this monitor handles both with ease.
I bought 2 of these to replace my old work-from-home Acer monitors (10 years old) and I gotta say, I’m pretty particular about my tech.First, I was annoyed that the base doesn’t raise, but get some monitor stands and you’re fine. (Amazon has some inexpensive ones and they give you a little nook and cranny under the monitor for your tchotchkes that TOTALLY don’t distract you from those 300 emails in your inbox).The vibrance, color, and quality of pic are great. Acer is .. aces.Setup was quick and easy, make sure you’ve updated your drivers and Windows just in case it gets weird when connecting them, and due to my job, I have to game with them (it’s a hard-knock life, for sure), and they deliver with no problem.They’re lightweight, work great for both work applications and gaming, and the response time is solid.Great price and functionality.

Amazing Monitor! The Stand? Not So Much.
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.

Phenomenal performance and stunning 1440p
I am beyond impressed with this Acer Nitro monitor. Upgrading from 1080p to QHD (2560 x 1440) is a total game-changer; the image density is perfect for a 27-inch screen. The colors on the IPS panel are vibrant and accurate right out of the box, with great viewing angles.The 180Hz refresh rate combined with AMD FreeSync makes gaming incredibly smooth with zero screen tearing. Whether I’m playing fast-paced shooters or immersive RPGs, the responsiveness is top-notch. For the price, you honestly can’t find a better balance of speed and image quality. Highly recommended for any serious gamer!

Me llego el día de hoy y lo he estado probando a lo largo del día. La mejora sobre mi anterior monitor que era FHD es muy notable, lo uso principalmente para gaming y me parece bastante bueno por el precio.

El monitor llego rápido, tiene buena calidad de imagen, solo que a mi me llegó con una leve rayada en la pantalla, el botón de encendido no funciona bien ya que lo tengo que oprimir muchas veces para que encienda y en ocasiones seguidas hace un parpadeo y se marca una línea horizontal. Voy a tener que devolverlo 😓
