AOC Agon AG27

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.

Otherwise, you've got a stunning 27-inch 1440p monitor with a 144Hz refresh rate and one-millisecond response time. So far it ticks all the boxes. The AG27 also has connectivity coming out of its eyeballs, with VGA, Dual-Link DVI, HDMI 2.0, HDMI-MHL and DisplayPort connections. 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 and an audio line in and headphone out.

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. At $415 for the FreeSync model, too, it's a lot of monitor at a great price.

Bottom line: It's a gorgeous display with the option for FreeSync and G-Sync. (The G-Sync version costs $549.)

One more thing: The 144hz refresh rate and a response time of just one millisecond make this ideal for a gaming machine.

Why the AOC Agon AG27 is the best PC Monitor

Not only does the AG27 look good, it performs well enough in games, making this somewhat affordable panel well worth considering.

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. There's even a headset stand that folds out, just to keep everything neat and tidy.

Best curved

Acer Predator X34

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.

Want a big, wide, and curved monitor for your games and willing to pay for the privilege? The Predator X34 doesn't come cheap (it starts at about $1,100), but it should definitely be on your list.

Bottom line: It's a 1440p curved beast of a display that falls a little short in the refresh rate department.

One more thing: This ultra-wide panel sports an aspect ratio of 21:9.

Best budget

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 $250. 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.

Bottom line: It's a really cheap display with decent response time and an array of ports.

One more thing: You can overclock the display to hit a refresh rate of 75Hz.

Best FreeSync

ASUS MG278Q

NVIDIA's G-Sync technology is great, but what about those of you with AMD Radeon graphics cards? Then you want a monitor equipped with FreeSync — AMD's own anti-tearing, anti-stuttering technology. Like this one: the ASUS MG278Q ($450).

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 2560 x 1440, 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.

If you want a gaming monitor to compliment your Radeon GPU, consider the ASUS MG278Q. Its high refresh rate and low response time make it perfect for all types of gaming.

Bottom line: It is perfect for any compatible AMD GPU.

One more thing: It'll operate up to 144Hz for butter-smooth gaming.

Best G-Sync

Dell Gaming S2417DG

The display is a little pricey for many gamers (coming it at $389.99), 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 165Hz, 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: It's a stunning display if you're OK with gaming at 1440p, enjoying one millisecond response time and a refresh rate of 165Hz.

One more thing: There's no VESA mount support, which is a shame.

Conclusion

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.
