Who is it for?

If you’ve been a fan of G-Sync, or you have been intrigued of how this technology can revolutionize your gaming experience, and if you have budget to upgrade your display for ultimate gaming set-up, then the BenQ XL2420G is for you. This display is best for hardcore gamers who want to experience smooth and nearly faultless gaming. It comes with great set of features and wide selection of I/O ports to complete your gaming rig. And it has the perfect size for dual monitor or even triple monitor gaming setup as well.

G-Sync Technology for the Best Gaming Experience

The best way to test BenQ XL2420G’s G-Sync capabilities is through FCAT of Nvidia's Frame Capture Analysis Tool, allowing users to toggle their display between V-Sync off, V-Sync on, and G-Sync on modes. This display had some minor screen tearing when tested with Heaven benchmark test in Ultra-quality mode at 4x anti-aliasing. It also showed noticeable blur when disabling V-sync. Activating V-sync on the other hand, significantly reduced screen tearing, while providing more fluid gameplay. This performance is further enhanced when switching the G-sync mode on, as the display smoother gaming action.

This monitor had no issues in running big title games like Crysis 3 (one of the most graphically demanding games today and used for benchmark testing for gaming displays). The benefits of G-Sync were even more obvious as screen tearing is completely eliminated.


Ultra-Fast 1ms Pixel Response and 144Hz Refresh Rate, with 9.7ms input lag for Ultra Smooth Gaming Experience

Aside from the G-Sync, the BenQ XL2420G also takes pride on its 1 millisecond pixel response time (currently the fastest in today’s market) and 144Hz refresh rate.

This means the screen is free from any blurring and ghosting artifacts. Along with these fast performance is the 9.7ms input lag, which is the slowest latency we can find today.


Good Color Accuracy and Grayscale Performance for All-Around Use

Chromaticity test shows BenQ monitor has very good color accuracy. Colors red, green and blue stayed pretty close to their ideal CIE coordinates. To compare the Acer XB280HKAOC G2460PGAsus ROG Swift PG287Q and Philips Brilliance 272G5 all have almost similar chromaticity test results, with slightly skewed green, quite a common issue among TN-based panels. The skewed green however, doesn’t affect the color quality in any noticeable way, colors stayed sharp and well saturated, even when playing action-packed Blu-ray movies like Captain America: The Winter Soldier

In terms of grayscale performance, the XL2420G is tested in 64-Step Gray-Scale test, which has been the standard of grayscale test today. The monitor performs pretty well, without any noticeable clipping (washed-out white) or crushed blacks (two or more dark shade appearing black), and no tinting at the middle of the scale.

Standard Viewing Angle Performance, Expected from TN-based Panel Monitors

The viewing angle of BenQ XL2420G is nothing but ordinary, which is what you can expect from a TN-based panel. When viewing from the side, minor color shifting starts at around 60⁰ from the center. The screen also darkens at around 50⁰ from the bottom. Not too bad, but also far from the ideal. Clearly, this monitor is made for gaming, where users have to sit directly in front of their computer screen.


Flicker-Free and Low Blue Light Technology for Longer and More Comfortable Gaming

If your eyes are particularly sensitive, then you will be happy to know that this gaming display comes with flicker-free and low blue light technologies, much like other BenQ gaming displays. The former gets rid of flicker which causes eye-strain and headache, while the latter actively reduces blue light emission from the screen, which also to helps reduce the risk of eye strain and allow hardcore gamers to play longer.


Decent Power Consumption with Power Saving Mode

This BenQ gaming monitor consumes 30 watts at Standard mode, which is about the same to one of its closest competitors like AOC G2460PG, which runs at 32 watts, but way higher than non G-sync gaming displays like AOC E2460SD-TAA, which runs at 18 watts. However, XL2420G comes equipped with Eco mode which brings the power consumption down to 14 watts.


VESA Mounting Holes for Optimum Ergonomic Setup

Should you wish to ditch the fully adjustable stand for full ergonomic setup, and use a more flexible and adjustable monitor stand, LCD arm, or desk mount, then it’s good to know that you can do that upgrade with this BenQ display, as the backside of its cabinet sports VESA standard mounting holes, with optional mounting kit. You can also mount the display on your wall using third-party wall mounts or put two BenQ XL2420G monitors side-by-side for dual monitor setup, or three for triple monitor setup.


Dual Monitor and Multiple Monitor Mounting Options

Many consider mid-sized displays, like 24-inch monitors, as the perfect size for gaming. It’s not too big making it convenient for your eyes to cover all areas of the screen and hover your mouse easily, and it’s not too small to present images and scenes in great details. Also, it makes up for a great dual monitor or even triple monitor setup.

If you’re looking for a cheap dual monitor setup solution, then you should check out the MonMount LCD-194 Dual LCD Monitor Stand. This stand can hold two monitors of up to 26 inches big, and can easily clamp on your desk, with stable and secured support. It comes with very few assembly pieces, making it really easy to put together and set up to your workstation.

If you want a stand that can is completely adjustable, with fully articulated arm, then you can opt for Ergotron LX Dual Stacking Arm. It can fully lift two mid-sized displays side-by-side or in stacking position to dual monitor setup. Also, it comes equipped with the brand’s patented CF (constant force) technology, which means you can move each of your display around independently, and set it to your most comfortable position.

Design and Features

The BenQ XL2420G sports the same design as the previous model in the XL series BenQ XL2402T and the bigger BenQ XL2720ZYou can check out our in-depth review of the latter here.  It’s a 24-inch monitor that utilizes TN panel to run at 1920 x 1080 resolution, and houses it in a 2.4-inch thick matte-black cabinet, with 0.75-inch thin bezels and shiny back panel.

Obviously, BenQ had to use a thicker cabinet to cram all various technologies and features to this monitor, making the cabinet of XL2420G look thicker than many of its G-sync competitors. This also makes the cabinet a little heavier, but surely, it’s a small price to pay for the performance and features it’s able to deliver. And like its older brother BenQ XL2420Z, this one also comes with the same metal carry-handle and headset holder.



Buttons and Controls

The right bezel houses the function buttons, and this gaming monitor certainly has ample buttons to help you set your display conveniently, and easily. There are capacitive sensors for the OSD (on-screen display) button, which are integrated with IR emitter at the upper edge of the monitor, helpful for 3D gaming, alongside with the Switch button.

The five (5) function buttons allow easy Menu access, as well as for changing Picture modes and display size mode (Aspect Ratio), and lets you toggle between G-Sync and Classic (non-G-Sync) mode.

BenQ XL2420G offers lots of Picture settings options, namely Brightness, Contrast, Color Temperature, Black eQualizer, Hue, Saturation and Sharpness. For Picture modes, this monitor comes with the basics, including Standard, Photo, Movie, Eco and sRGB. But it also features three gaming-optimized modes, all designed for different types of gaming, namely FPS1, FPS2 and RTS, alongside with another three customizable modes (Gamer 1, Gamer 2, and Gamer 3.

The Display Mode menu has nine (9) aspect ratios, including settings that emulates the screen size of 17 to 23 inches range, and a buzzer option that lets you set timer for your gaming sessions.


The Trusted S-Switch for Quicker and Easy OSD Access and Intuitive Navigation

Just like its other G-sync gaming display BenQ BL3200PT, the XL2420G comes with a nifty accessory that you need to plug into the back side of the panel - the S-switch. This switch sets this product apart from other G-sync monitors in the market today. It’s a wedge shape device that houses three large red buttons that gives users quick access to any of the monitor’s three (3) pre-selected display modes.

There’s also a small button on top for easy navigation of the OSD, along with a scroll wheel which also works as a selector. The S-switch allows quick and easy navigation and selection of the OSD.


Generous Selection of I/O Ports

One of the few things that set this display apart from other G-sync monitors is its generous selection of video inputs. Most G-sync monitors out there only come with DisplayPort. The BenQ XL2420G on the other hand, has two (2) HDMI inputs, and dual-link DVI input, along with the DisplayPort. It also comes equipped a mini USB port for S-Switch use, and four (4) USB 2.0 ports of two upstream and two downstream ports. Both are nicely placed on the left side of the cabinet, together with the headphone jack, making it easy and convenient for users to connect their peripherals and gadgets to the monitor.


Solid Base, Flexible Stand with Cable Management Slot

The bigger and heavier cabinet means more robust stand, and BenQ did not fail in this category. The BenQ XL2420G is equipped with solid and heavy base, which boasts some pretty impressive adjustability features. This stand sports a T-shaped hinge which allows the adjustments, namely good height adjustment range of 5.11 inches, can tilt up to 25⁰ (5⁰ forward, 20⁰ backward), swivel left and right, and pivot to switch from landscape to portrait orientation mode, and vice versa.

There’s also a red slot at the bottom of the mounting arm that can be used for organizing computer cables, helping you keep your workstation, or should I say gaming station, neat and clean.


Tech Specs

Package includes the DVI, DisplayPort, and USB cables, a resource CD, and a dust cover.

Bottom Line

There’s certainly a lot to love about BenQ XL2420G, it has outstanding gaming performance paired perfectly with good color and grayscale reproduction. When used with Nvidia graphics PC, this display can provide superb gaming experience with crisp and stutter-free gameplay. You can be sure there will be no screen tear or various motion artifacts to distract your viewing and gaming experience.

It may cost $200 more than its close rival AOC G2460PG and other G-Sync enabled monitors, but the cost can be justified with its generous selection of I/O ports, namely HDMi and DVI video inputs, adds flexibility to the monitor’s functionality, as it can be easily paired with various peripherals and connect your handheld gadgets like smartphones and tablets. Plus, it also has advanced picture settings and preset modes to allow users, particularly gamers, to further optimize the screen to fit their gaming needs and different specific applications. Also, it comes with VESA-standard mounting holes, making it convenient for gamers to make dual monitor or even triple monitor setup with the use of third-party ergonomic products such as monitor stands, LCD arms, desk mounts and even wall mounts.

If there’s anything BenQ can improve in this display, it would be in its contrast ratio. USB 2.0 hub is okay, but it would be nicer if they included a couple of USB 3.0 ports as well. The narrow viewing angle is a typical problem among TN-based panels, which makes it not a big issue.

All in all, the BenQ XL2420G is a great display that offers G-Sync functionality, with the usual BenQ build quality that we can expect to last long. It’s an excellent gaming monitor for those who are willing to stump up the cash.
