Do you need a monitor for programming?  

Technically, almost any monitor can work and, because of this, monitor makers often fail to market their displays specifically to programmers. However, BenQ is addressing this gap with its latest line of programming monitors. We’ve previously reviewed the BenQ RD280U, which is notable for its distinctive 3:2 aspect ratio. However, the company also offers the more traditional RD320U, a 32-inch 16:9 4K display packed with features tailored to meet the needs of programmers. 

BenQ RD320U specs and features 

At its core, the BenQ RD320U is a solid 32-inch 4K display. It has an IPS Black panel (which should improve the contrast ratio) and delivers a sharp image at 3840×2160 resolution. 

• Display size: 32-inch 16:9 widescreen 
• Native resolution: 3840×2160 
• Panel type: IPS Black 
• Refresh rate: Up to 75Hz 
• Adaptive sync: None 
• HDR: Yes, VESA DisplayHDR 400 Certified 
• Ports: 2x HDMI 2.0, 1x DisplayPort 1.4, 1x USB-C with 90 watts of Power Delivery and DisplayPort Alternate Mode, 1x USB-B 3.2 Gen 1 upstream, 2x USB-A 3.2 Gen 2 downstream, 2x USB-C 3.2 Gen 2 downstream, 3.5mm audio-out 
• VESA mount: 100x100mm 
• Speakers: 2x 3-watt speakers 
• Price: $649.99 MSRP 

It’s also jam-packed with ports, including a USB-C port with DisplayPort and USB Power Delivery. Though pitched to programmers, the RD320U’s specifications make it a competitor to high-end home office monitors like the Dell Ultrasharp U3223QE and Philips Creator Series 27E2F7901.

BenQ RD320U design  

At a glance, the BenQ RD320U’s design is basic. It’s clad in various shades of charcoal black that don’t immediately catch your eye. Take a second look, though, and you’ll notice the details, like the rippled pattern that cascades down the rear of the monitor and the lower display bezel. These add a subtle bit of flair that makes the monitor distinct from its competition. 

The star of the show, however, is in fact a moon — or MoonHalo, as BenQ calls it. The MoonHalo is a ring of LED lights centered on the rear of the monitor. It’s like the RGB-LED lights on gaming monitors, but instead meant to provide soft, consistent ambient light. The MoonHalo is always white, but you can adjust the color temperature to match the display. I enjoyed the MoonHalo; it looks nice and I felt it made the display less tiring to view after dark.

The monitor ships with an ergonomic stand that adjusts for height, tilt, pivot, and swivel. The stand is attached to a mid-sized, flat base. It’s a bit wider than it needs to be, but since it’s flat, the desk space it occupies remains usable. I’m not a fan of the stand’s cable management, however. The faux-leather strap BenQ provides for the purpose is attractive but can’t hold many cables. 

While the included stand is nice, BenQ also provides a 100x100mm VESA mount for use with third-party monitor arms and stands. 

BenQ RD320U connectivity and menus  

The BenQ RD320U has four video inputs: two HDMI, one DisplayPort, and one USB-C with DisplayPort. To be honest, I’d rather it had two DisplayPort ports than two HDMI, but that’s a nitpick. This is a solid range of video connectivity.  

In addition to DisplayPort, the USB-C port also provides up to 90 watts of USB Power Delivery and supports data for connections to multiple downstream USB-A and USB-C ports. Two USB-A ports, and one USB-C port, are located on the monitor’s chin, which makes them easy to access. A KVM switch function is included, too. 

A USB-B upstream port provides an alternative way to connect to the monitor’s USB hub, which is useful if your PC lacks USB-C.  

The BenQ RD320U’s USB connectivity isn’t as extensive as the Dell Ultrasharp U3223QE, which has more USB ports and provides Ethernet, so those looking for a USB hub should give Dell’s alternative a look. Still, the BenQ’s connectivity is a hair above average, as it delivers several downstream USB ports and places them in convenient locations.

BenQ’s on-screen menus are accessed with a quick, responsive joystick centered on the monitor’s chin. The menu is large, which makes it easier to see and read (though, unfortunately, the menu’s font is still a bit thin). I also found the menus logically arranged and had no issues finding the settings I want. BenQ, like most of its competitors, also provides a Windows software utility (Display Pilot 2) to access and control monitor settings. 

The BenQ RD320U’s image quality options are a bit underwhelming. It uses vague presets for gamma and color temperature instead of providing the proper, numerical labels. An sRGB color gamut preset is available, but no preset is available for DCI-P3 or AdobeRGB. I understand this isn’t a “creator” monitor, but its performance is certainly good enough to make these presets useful. 

Programmers won’t mind, however, because the RD320U offers several features that come in handy while coding. This includes two preset “Coding Booster” modes that adjust brightness, contrast, and gamma to make code easy to read.  

The monitor also has an ambient light sensor that can automatically adjust the monitor’s brightness throughout the day. The ambient light sensor is pitched to programmers as a way to reduce eye strain, but the feature is just as useful for writers, creators, accountants, and anyone else who spends a lot of time in front of a monitor. 

Speakers are included, but they’re not great. The pair of bundled 3-watt speakers produce sound with reasonable clarity at low volumes but quickly become overwhelmed as volume is increased. They’re fine for listening to a podcast or playing soft, ambient tones, but speakers or headphones will be necessary for true audio enjoyment.  

BenQ RD320U SDR image quality 

The BenQ RD320U is a great example of a monitor that doesn’t necessarily need great image quality to satisfy its intended user. Programmers are staring at code, right? Fortunately, BenQ doesn’t use that as an excuse to deliver half-baked SDR image quality. On the contrary, the BenQ RD320U looks great.

BenQ gets off to a great start in brightness, as the RD320U delivers an excellent 426 nits of peak SDR luminance. That’s a lot, and certainly far more than most programmers will need.  

Still, a high level of SDR brightness means the monitor remains usable in a brightly lit room. That’s good news if your office has sunlit windows or you’re coding in a bullpen that looks straight out of The Wolf of Wall Street.

There’s more good news in contrast, as the BenQ RD320U comes close to delivering a contrast ratio of 2000:1. BenQ doesn’t market the monitor as having an “IPS Black” display panel, but this is a level of contrast I’ve only witnessed in IPS panels of that type. It keeps the RD320U competitive with class leaders like the Dell U3223QE and
