    • Best improvement I’ve made for gaming pc

    • BEST BUDGET MONITOR
Size: 27" 180Hz VA
Honestly, for the price point, it is a great monitor. The colors were vibrant and the brightness of the screen was great (despite it not being an IPS). You will not complain about the brightness. The HDR functionally really makes your screen pop out and makes the display very nice. I use a monitor stand, so I cannot say much on the functionality of the monitor legs. ... show more

    • Great monitor for the money
Size: 27" 180Hz VA
I’ve been using the AOC Q27G4XN 27” QHD gaming monitor for a bit now, and honestly it’s been a great value for the price. The 2560x1440 resolution looks sharp and clean, especially on a 27” screen, and the high refresh rate makes gaming feel incredibly smooth. Fast movement looks great, input lag feels minimal, and overall gameplay is responsive without spending premium monitor money. What surprised me most was how good it looks for everyday use too. Colors are solid, text is crisp, and it works well for both gaming and productivity. The adjustable stand is a nice touch, and setup was straightforward. No major complaints so far. If you’re looking for a solid 1440p gaming monitor without breaking the bank, this one is definitely worth considering. ... show more

    • Perfect monitor
Size: 27" 180Hz VA
I have had this monitor for a long time now, and I must say I really do love it! The screen quality is nice, and the brightness is great. The size is perfect for a small desk that I have, and the color range for gaming is great!

    • 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

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

    • 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

    • Awesome for the price
Size: 27" 180Hz VA
Picked this up on a slight sale, and it is perfect for the price. I primarily use it for PS5. 1440p at this screen size (assuming viewing distance is 24” or less) is just right. Brightness leaves a bit to be desired but it has great colors and motion handling.
