As professionals, we rely heavily on our monitors to provide the tools we need to complete our work. 

A high-quality display is essential for tasks such as photo and video editing, design work, and other charges that require precise color accuracy and detail. The BenQ PD3420Q is a 34-inch ultra-wide QHD monitor that aims to provide professionals with precisely that – a reliable and capable display that can easily handle a wide range of tasks. 


Upon unboxing the BenQ PD3420Q, we were immediately impressed by its sleek and stylish design. The monitor has a slim bezel and an elegant stand that gives it a modern and professional appearance. Inside the box, we found the monitor, a power cord, an HDMI cable, a DisplayPort cable, and some documentation. Including both HDMI and DisplayPort cables is a nice touch, as it gives users more flexibility regarding how they want to connect the monitor to their computer.

Setting up the BenQ PD3420Q was a straightforward process, and we were up and running in no time. The first thing we noticed when turning on the monitor was the excellent image quality. The 34-inch QHD display has a resolution of 3440x1440, which provides plenty of detail and sharpness. The colors were also impressive, with good vibrancy and accuracy. The wide viewing angles were also a plus, as they allowed us to easily view the display from any angle without losing quality.

In use

We put the BenQ PD3420Q through its paces during our testing, and it performed admirably across various tasks. The image quality remained consistently excellent throughout our tests, with good color accuracy and detail. The ultra-wide QHD display was handy for tasks such as photo editing, as it provided plenty of screen real estate to work with. The 100% sRGB coverage and flicker-free technology were also appreciated, as they helped to reduce eye strain and make our work sessions more comfortable.

One feature we particularly appreciated was the low blue light filter, which helps reduce the amount of harmful blue light emitted by the display. This is especially useful for those who work long hours in front of a screen, as it can help to reduce the risk of eye fatigue and other related issues.

In terms of connectivity, the BenQ PD3420Q offers both HDMI and DisplayPort connections, which gives users some flexibility regarding how they want to connect the monitor to their computer. We had no issues with connectivity during our tests, and the display worked seamlessly with our computer.

The BenQ PD3420Q also has several additional features that make it a versatile and powerful monitor. For example, it has a Picture-by-Picture (PBP) feature that allows you to connect two different sources to the monitor and display them side by side. This can be useful for professionals working with multiple sources simultaneously, such as comparing design layouts or working with video and audio files.

The monitor also has a Picture-in-Picture (PIP) feature, which allows you to display a smaller window within the main display. This can be useful for tasks such as video conferencing or keeping an eye on your email while working on something else.

Another feature worth mentioning is the Display Pilot software, which allows you to customize and optimize the display settings to suit your specific needs. The software includes various features such as split-screen options, color temperature adjustments, and more.

In addition to these features, the BenQ PD3420Q has several advanced connectivity options. It has a USB-C port, allowing quick and easy data transfer and charging devices such as laptops and smartphones. It also has a built-in KVM switch, enabling you to control multiple computers using a single keyboard and mouse. This can be particularly useful for professionals working simultaneously with numerous computers.

One potential drawback of the BenQ PD3420Q is its price. It is a high-end monitor with advanced features and impressive specifications, and as such, it comes with a higher price tag that some other alternative options.

While this may be a deal breaker for some, it's worth noting that you get what you pay for, and the BenQ PD3420Q is certainly a top-quality monitor that is well worth the investment for professionals who need a reliable and capable display.

However, if you're willing to invest in a high-quality display that can handle a variety of tasks with ease, the BenQ PD3420Q is worth considering.
