Best 4K: Acer Predator X27

If you’re looking for a gaming monitor that really pushes the limits, then take a hard look at Acer’s Predator X27. It has a 27-inch display with a 4K resolution at 3840 x 2160 pixels, giving you an incredibly clear image. On top of that, it’s an IPS panel, so you’ll get wide viewing angles. That’s handy in case you’re planning to set it up for watching TV and movies as well.

While the monitor runs at a 120Hz refresh rate, it can be overclocked to 144Hz, offering incredibly smooth video game visuals. Although the IPS panel keeps it from being responsive as TN (twisted nematic) panels tend to offer, it manages a snappy four millisecond response time, so your actions will quickly show on the display with minimal lag.

That trade-off is made up for with an incredible picture quality thanks to G-Sync HDR, which offers darker blacks and brighter whites. It also has 384 dynamic backlight zones and meets the VESA standard for DisplayHDR 1000, the display industry's norm for defining HDR quality. You’ll need an incredibly powerful computer to get the most out of this monitor, but if you can run video games at 4K and 144Hz, this is the monitor to do it with full, G-Sync ultimate flair.

Runner-Up, Best 4K: Asus ROG Swift PG27UQ

Asus has another premium option for you to sink into 4K gaming at up to 144Hz with complete G-sync compatibility. Compared to other 4K options, which one is better will really come down to your brand preference. If you have a lot of other Asus accessories, this ROG Swift PG27UQ may blend into your setup better.

Other than some brand and styling differences, this monitor offers up comparable specs. Beyond the 4K IPS display with G-Sync HDR and VESA DisplayHDR 1000, it offers a wide color gamut with 97 percent DCI-P3 and a resolution of 3840 x 2160 pixels. It also has 99 percent coverage of the Adobe RGB color space, allowing for realistic colors and contrast.

On the back, you have the option of HDMI or DisplayPort for your video connections. It also has a USB 3.0 hub, so you can easily wire peripherals through the monitor to your computer.

Best 1440p: Acer Predator XB271HU

While gaming with high frame rates at 4K is tough for even expensive computers, hitting over 100 frames-per-second on a 1440p monitor is much more attainable. That makes them a sweet pick for gamers, and the price isn’t nearly as hard to stomach as a 4K monitor. Acer leads the pack with the Predator XB271HU 27-inch gaming monitor.

This monitor offers a default refresh rate of 144Hz, but it can overclock to 165Hz. And, with G-Sync, you get full variable refresh rates from 1Hz up to that overclocked 165Hz rate. While HDMI is supported, you’ll need to use DisplayPort to get the full benefit of the monitor's speeds. We picked the IPS-panel version for the improved viewing angles, but that limits it to a four millisecond response time. If you prefer faster, it’s also available in a TN-panel variant.

Beyond the crisp display of 2560 x 1440 pixels, you get a highly adjustable monitor stand, support for USB 3.0 pass-through, and dual two-watt speakers for when you need sound but don’t have headphones handy. The Predator XB271HU can also be mounted using a VESA stand.

Runner-up, Best 1440p: ViewSonic XG2760

If you don’t need an IPS panel but still want a 1440p resolution, 27-inch monitor with refresh rates up to 165Hz, ViewSonic has a well-priced option in the XG2760. This is a monitor that offers a good blend of speed and visual quality, with a screen resolution of 2560 x 1440 pixels.

While it has a TN panel, meaning you won’t be getting great viewing angles and will want to keep it directly in front of you, you also get excellent one millisecond response times with overdrive. To hit the 165Hz max refresh rate on this monitor, you’ll need a DisplayPort 1.2a connection, but that’ll also offer your G-Sync variable refresh rates from 1Hz up to 165Hz, so your game always stays free of tearing and stutters.

The XG2760 can also help keep your desk setup clean. There is a USB hub on the back for two USB 2.0 and two USB 3.0 connections. If you want to connect a game console, there’s also an HDMI connector. In addition, the 3.5mm audio jack can let you easily connect headphones or speakers.

Best Full HD: Asus ROG Swift PG258Q

When all that matters to you is speed, you can forget about the extra high resolutions of 4K and 1440p. That trade-off will not only let your computer run games faster, but you can also find monitors that refresh faster. Asus has a blisteringly fast G-Sync monitor with its ROG Swift PG258Q.

You’ll still be getting a clear picture with a Full HD panel that measures 24.5 inches diagonally and a resolution of 1920 x 1080 pixels, but the images can be buttery smooth with G-Sync available from 1Hz up to its maximum 240Hz refresh rate. If you’re into e-sports and want to see all of the action clearly, this monitor will help ensure that you see every frame possible without any tearing or stuttering.

You can connect to the monitor with DisplayPort 1.2 and HDMI 1.4. You also get a USB hub or two USB 3.0 connections, helping you keep your gaming rig tidy. The monitor stand is also flexible with height adjustment, 25-degrees of tilt, and the option to rotate the monitor vertically.

Runner-up, Best Full HD: BenQ XL2740

If you want a lot of screen with clear, 1080p resolution and a blazing fast 240Hz refresh rate, we have another option for you. The BenQ Zowie XL2740 is still pricey, but you get a 27-inch panel for a large picture with smooth imagery at
1920 x 1080 pixels.

This is a G-Sync compatible monitor, so it doesn’t support variable refresh rates from 1Hz up to 240Hz, but it does manage 48 to 240Hz. And, being realistic, it’s unlikely you’re going to drop down below 48 frames per second if you’re usually hitting over 200 frames per second in your favorite games. So, you can be sure you’ll have a stutter-free, tear-free experience at high frame rates as long as you have the computer to pull it off. Better yet, this monitor has a one millisecond response time for uninterrupted gameplay.

Beyond the screen, you get a height- and angle-adjustable monitor stand, two HDMI inputs, one DisplayPort 1.2 input, a headphone and mic jack, and a built-in USB hub. It also comes with detachable shields that can help you focus and block out any background environment.

Best G-Sync Compatible: Acer Nitro XV273K

If you're hoping to get something similar to a 4K G-Sync monitor at a lower cost, we have a G-Sync compatible version that will fit the bill. Acer’s Nitro XV273K is a 27-inch monitor with an IPS panel that boasts a 4K resolution of 3840 x 2160 pixels and a refresh rate up to 144Hz (the G-Sync variable refresh rate supported by this monitor is limited to 48 to 120Hz, though.)

Though the Nitro XV273K drops the price significantly, it still has some higher-end qualities. For one, it supports 1.07 billion colors and VESA Display HDR 400, which improves color and contrast. It also covers 90 percent of the DCI-P3 color space — in other words, the imagery is going to look crisp because of the 4K resolution, and vibrant thanks to the colors and HDR.

The monitor supports HDMI and DisplayPort connections, so you can connect multiple devices. It also has USB passthrough to help you reduce the number of cables you need to run on your computer, as well as dual, four-watt speakers to offer sound when you don’t have headphones.

Best Value: Acer XG270HU

For a solid, middle-of-the-road option, go with the Acer XG270HU. This is an older model, but it was built to support AMD’s FreeSync variable refresh rate technology. Fortunately, it also nabbed a G-Sync compatible label with support variable refresh rates from 40Hz up to 144Hz.

While its age does come with some limited features, this monitor still excels in gaming performance. It boasts a 27-inch, 1440p TN panel with a native 144Hz refresh rate and one millisecond response time. You'll also get an HDMI, DisplayPort, and DVI port in the rear for connecting a video source. For audio, there are 3.5-millimeter audio in and out jacks as well as dual speakers, though they aren’t the loudest. The screen even has narrow bezels on the top and sides.

You do miss out on a USB hub, HDR, and the monitor stand isn’t incredibly adjustable. Still, the Acer XG270HU is much cheaper than a lot of the competition while still giving beautiful gameplay with a resolution of 2560 x 1440 pixels, and G-Sync support just makes the visuals that much better.
