    • Great panel
Size: 27" 180Hz VA
Great panel, runs good, colors are a little oversaturated / overbold on default settings for non-gaming purposes but easily dialed back. On screen display has many settings and is highly customizable, which may be confusing at first but is nice once figured out. Excellent contrast and certainly bright enough for sunlit rooms. Looks amazing in the dark. Good for movies, office work, text, games, etc. It's a VA panel. On medium overdrive I don't notice any artifacts unless I specifically hunt for them and I'm fairly particular. I haven't thought about it since setting up the display. You do have to turn this on manually in the OSD. IMO it's a non-issue on this panel. Included stand is sturdy, small, and highly functional, providing all necessary mobility (vertical height, 2-way swivel) in many setups without taking up much desk space or requiring you to set up an arm etc. It's flat also, and is a convenient place for thumbdrives, pens, etc. Really nice feature. The styling is right on the edge of being too 'gaming' for a normal person's computer. The minimalist aesthetic used for the stand and front face save it. Would buy again, and recommend as a default 27in display for non-arm setups that require a vivid, high contrast, high refresh rate display. ... show more

    • AOC Q27G4XN 27" Monitor - Great Performance and Value, Highly Recommended
Size: 27" 180Hz VA
I picked up the AOC Q27G4XN for my second setup, and I’ve been really impressed so far. For the price, this monitor delivers a lot more than I expected. SETUP AND FIRST IMPRESSIONS Right out of the box, setup was quick and easy. The stand is sturdy and lets you adjust the height, tilt, and swivel, which makes a big difference if you use it for long sessions. The overall build feels solid and not flimsy like some other budget monitors. DISPLAY AND PERFORMANCE The 27-inch screen with 2560x1440 (2K QHD) resolution looks sharp and clear for both games and everyday use. Colors are bright, and I didn’t notice any dead or bright pixels. The 180Hz refresh rate and 1ms response time make games look super smooth, and Adaptive-Sync keeps things free of tearing or stutter. I tested it with both a PC and an Xbox, and had no issues—HDMI 2.0 and DisplayPort both worked as expected. FEATURES The monitor comes with two HDMI ports and one DisplayPort, so you can easily switch between devices like consoles or a laptop. The 3-year zero-bright-dot warranty is a nice bonus for peace of mind. PROS: Crisp, sharp QHD picture with good color Super smooth 180Hz refresh rate and 1ms response Adjustable stand for better comfort Plenty of ports for different devices Great value for the specs Reliable warranty CONS: Built-in speakers are average (like most monitors) The menu buttons could be easier to use SUMMARY AOC might not get as much hype as other brands, but this monitor is solid. For gaming and everyday tasks, it’s been excellent - especially at the price I paid. Highly recommend for anyone wanting a quality QHD monitor without breaking the bank. ... show more

I'll be honest i bought this because it was among the cheapest 27" i could find. Wasn't expecting much, i had spent alot on the pc and desk, and everything else i just needed any display. I paid $139.99 for this monitor and I've been pleasantly surprised and impressed. It's worked flawlessly with my switch 2 and pc. VA panels have gotten so good in recent years and offer a kind of similar experience to oled panels for a fraction of the price, they're great with high contrast and deep blacks. Obviously nowhere near a good oled panel but lets be honest 140 bucks for this thing is a killer deal. Highly recommend. I love the little channel in the stand for cable management, 2x hdmi is great and even a 1.8mm jack for running speakers if you need, the height and angle adjustmentis very smooth and well thought out. Good product for the price. It doesn't translate well through a picture but it looks really good with all the games I've played. ... show more

    • Absolutely blew away expectations
Size: 27" 180Hz VA
Absolutely massive upgrade coming from an older 27" 1080P 60HZ panel... So if you're worried you will not be impressed from a visual standpoint and have an older 1080P monitor, just get it. This makes everything pop, and the Nvidia control panel showed this had VRR settings with no tweaks needed. If you're worried about the cheaper version with the VA panel not being as good as the oled or whatever, you have nothing to worry about. Honestly, if I ordered the OLED model and they sent me this by mistake, I would have probably thought this was OLED... It's that good. 2560x1400 is noticeably better than 1080P, but then you also have the ability to do this insane refresh rate of 180hz.. for roughly $140 wth... 2025 is a great year to be alive. My rig with a 13700k and 1080ti finally has a monitor that shows its true potential ... show more

    • Great bang for your buck
Size: 27" 180Hz VA
Looks great, has the IPS glow but its not bad at all. I play a lot of milsims and it does a great job with shadows and textures. The controls are easy to navigate. Refresh rate is higher than I need, but the overhead is nice. Definitely worth the money I spend on it.

    • Great monitor for the price, no built-in audio.
Size: 27" 180Hz VA
I got it on sale for about $160. It was easy to put together and set up. It does come with a power cable, a DP and HDMI cable as well. The monitor is flat-screen, which I like. It is quite impressive, with the 2K resolution looks crisp and clear, and the high refresh is buttery smooth. Since it is a VA panel (some type of LCD), I do notice ghosting with dark colors. The contrast is great as well. It has buttons on the bottom, to adjust volume, tweak the display, change source, and a few others, which is nice. The biggest downside to me is that it has no built-in speakers. It does have an AUX jack in the monitor. After a month of use though, I have yet to come across any issues. ... show more

    • Great color and smooth response for World of Warcraft
Size: 27" 180Hz VA
Review Image by Cece
I primarily use this monitor for playing World of Warcraft, and it has worked very well for that. The colors look vibrant and make the different environments, characters, and effects stand out nicely without appearing washed out. The response time also feels quick and smooth during gameplay. I have not noticed any distracting delay or sluggishness while moving through busy areas or during combat, which was one of the most important things I wanted from a gaming monitor. The 27-inch screen provides plenty of viewing space, and the 2K resolution is a nice match for gaming without making the monitor feel excessively large on a desk. For my setup and the games I play, it delivers the color and responsiveness I was looking for. I have not found any real drawbacks so far. It has been a reliable gaming monitor and an easy five-star choice for me. ... show more
