A gaming monitor can make the difference between simply watching what's displayed on-screen and truly immersing oneself in the game. AOC Agon AG27 is one of the better value displays you can buy with a solid refresh rate, response time and support for NVIDIA G-Sync.

Our pick

AOC Agon AG27

FreeSync and G-Sync options, 144Hz refresh rate, and a beautiful 27-inch picture.

One of the first things to know about the AG27 from AOC is that you can have a great gaming time whether you use NVIDIA or AMD graphics. That's because you can get the same basic monitor with either G-Sync or FreeSync support, with the difference being the price; G-Sync costs a bundle more at about $620 compared to about $400.

Who should buy this PC display

When you need to game on your PC, you need a gaming display that can handle all the pixels sent by your GPU. Adding synchronization technology to the mix really makes your game catalog shine, no matter what you play. Partnering up an AMD or NVIDIA GPU with the respective AG27 display makes everything look spectacular.

Is it a good time to buy this display?

It's a perfect time to purchase the AG27. Gaming monitors are refreshed on an irregular basis and while this display has been out for some time, it's still one of the better panels offered by AOC. You'll be good for years to come with the 165Hz refresh rate and available inputs.

Reasons to buy

  • 165Hz refresh rate.
  • Great colors and viewing angles.
  • Low blue light setting.
  • NVIDIA G-Sync and AMD FreeSync.
  • Built-in headphone stand.

Reasons not to buy

  • USB hub is awkwardly placed.
  • Poor calibration out of the box.

Best of both worlds

AOC doesn't play favorites, which is why the company offers two variants of the AG27, one for FreeSync and the other G-Sync. This allows both AMD and NVIDIA fans to take full advantage of both technologies by picking the monitor that matches their GPU. Throw in a refresh rate of 144Hz and a response time of just one millisecond and you have a killer display.

Connectivity is also solid with VGA, Dual-Link DVI, HDMI 2.0, HDMI-MHL and DisplayPort available. There are also four USB 3.0 ports (one of which is a dedicated fast charge port for your smartphone) as well as two integrated 3W speakers.

AOC AG27 makes your games look stunning on PC.

And if you need a place to keep your headset, no problems, it's got a stand for that as well. One final party trick is the included remote, which allows you quick one-press access to up to three different configurations. The main drawback to this display is the out-the-box calibration, which isn't great. You'll want to use a calibrator to really get games looking spectacular on-screen.

Alternatives to the AOC AG27

The AG27 may be our favorite display, but there are other fantastic PC monitors out there for different requirements.

Runner-up

Dell Gaming S2417DG

Small but capable.

For something a bit cheaper and smaller than AOC's 27-inch model, there's this 24-inch gaming monitor. It takes advantage of NVIDIA's G-Sync technology for a smooth and stutter-free picture, and the 165Hz refresh rate is above and beyond what most monitors offer.

It has a 2,560 x 1,440 (QHD) resolution and a one-millisecond response time, and the stand allows it to be set in landscape or portrait mode, perfect for a multi-monitor setup. You can connect with HDMI, DisplayPort, and four USB-A 3.0 ports.

Curved pick

Acer Predator X34

Wrapping the game around you.

If you're in the market for a huge curved monitor, the Acer Predator X34 has you covered. It has a 34-inch LED display with a 21:9 aspect ratio that is, yes, curved. And boy, does it look nice. Bask in its 3440 x 1440 resolution that, while short of 4K, still gives users a beautiful picture. First-person shooter (FPS) enthusiasts will appreciate the 60Hz refresh rate that can be overclocked to 100Hz.

Although this monitor only has a four-millisecond response time (slower than some other monitors), it was also the first curved monitor to feature G-Sync technology. The in-plane switching (IPS) panel also delivers amazing color reproduction. The X34 has some cosmetic, utility, and design features you might also enjoy, like the ambient lighting on its underside, five USB ports (basically a built-in hub), built-in speakers, and a built-in webcam. This monitor comes with a VESA mount adapter that fits on most 100 mm x 100 mm mounts.

Value pick

ASUS VG248QE

When on a tight budget, ASUS has a great monitor for you.

Say you're an FPS enthusiast who really wants to augment their game with a new monitor, yet you don't have the funds to support your ambition. ASUS has you covered. The VG248QE has a 144Hz refresh rate and a one-millisecond response time and can be obtained for about $270. Unbelievable, right? The 24-inch LED display has a 1080p resolution and a 16:9 aspect ratio.

The stand allows for tilt and swivel and can be removed entirely to allow for wall mounting. The monitor has DisplayPort, HDMI, and DVI-DL ports, two speakers, and a headphone jack. Although the ASUS VG248QE lacks some of the utility of other monitors to keep the price down, ASUS chose against cutting performance. If you're looking for a monitor designed for fast response times and refresh rates without breaking the bank, consider the VG248QE.

FreeSync pick

ASUS MG278Q

When on a tight budget, ASUS has a great monitor for you.

NVIDIA's G-Sync technology is great, but those of you with AMD Radeon graphics cards want a monitor equipped with FreeSync — like this one, the ASUS MG278Q. It has a 27-inch LED display with a whopping 144Hz refresh rate and a one-millisecond response time. Coupled with AMD FreeSync technology, expect the smoothest picture while you game.

Native resolution on this monitor is 2,560 x 1,440, and its aspect ratio is a standard 16:9. It has a TN panel, meaning you get the incredible response time with less power draw but suffer from some wide-angle color distortions. This shouldn't be a problem, though, since you're generally seated directly in front of your monitor. Your eyes will thank you during marathon gaming sessions, thanks to ASUS's Ultra-Low blue light filter and flicker-free technology. Connections are versatile; the monitor has two HDMI ports and single ports for DVI-DL. DisplayPort, and USB 3.0.

G-Sync pick

Dell Gaming S2716DG

Sync up your gameplay.

The display is a little pricey for many gamers, but we are talking a seriously good-looking monitor with some killer features that will take your gaming experience to the next level.

Should you have a compatible NVIDIA GPU, the company's G-Sync technology will be able to work alongside the graphics card to reduce screen tearing, input lag and synchronize everything. With a native refresh rate of 144Hz, the 1440p panel will allow for some smooth gaming indeed. Connectivity includes a DisplayPort 1.2a, HDMI 1.4 and a few USB 3.0 ports for good measure. It's not the best, but it could certainly be worse. While it's only a 1440p display, G-Sync adds some cost, which needs to be considered.

Bottom line

There are a number of quality monitors available for purchase, depending on what GPU you use and how much computing power is available. Overall, the Agon AG27 by AOC is a solid panel with excellent visuals.
