Greatest Costs At the moment: Dell Professional 34 Plus USB-C

Ultrawide displays are a terrific possibility for workplace productiveness, and, at a look, the Dell Professional 34 Plus appears excellent for the house workplace. It has a 34-inch IPS panel with good brightness and readability, in addition to intensive USB-C connectivity. Nevertheless, the monitor’s pricing and general picture high quality slim its attraction.

Learn on to study extra, then see our roundup of the very best displays for comparability.

Dell Professional 34 Plus USB-C P3425WE specs and options

A take a look at the Dell Professional 34 Plus USB-C’s spec sheet rapidly reveals what the monitor is about: connectivity. The monitor has a USB-C port with as much as 90 watts of Energy Supply. That connects to 1 USB-C and three USB-A downstream ports. Ethernet is supported, too.

• Further options: KVM swap, Dell Show and Peripheral Supervisor help

Nevertheless, the monitor’s options are in any other case reserved. The monitor notably lacks the IPS Black know-how present in Dell’s flagship widescreen displays. It doesn’t have built-in audio system both, and has a restricted vary of picture high quality customization.

Dell Professional 34 Plus USB-C design

The Dell Professional 34 Plus deviates a bit from the design of prior ultrawide displays. As an alternative of a silver or white colorway, Dell has moved again in the direction of a conservative, all-black look. It is smart for the monitor’s supposed patrons, which embrace each companies and residential workplace customers, but it surely’s bland.

Surprisingly, the monitor stand continues to be silver. It appears like Dell caught with an current silver monitor stand as a result of, uh, that’s what that they had readily available. It’s not the top of the world, but it surely’s not nice. Seems to be apart, the monitor’s materials high quality is sweet. The plastics really feel agency and have a lovely texture.

It’s a curved monitor, as properly, although solely simply. The curve is clear when viewing the monitor from above or beneath, however not apparent when viewing the monitor straight-on. Whereas I’d desire a flat display for an workplace monitor, the Dell’s curve is adequately subtle that I didn’t thoughts.

The stand gives a better-than-average vary of changes for top and swivel, with 150mm for the previous and 60 levels for the latter. The stand can’t rotate 90 levels to be used in portrait orientation, however that’s typical for an ultrawide monitor. It’s just too extensive to virtually help it.

A 100x100mm VESA mount can also be accessible to be used with third-party monitor stands and arms. The panel (with out stand) weighs lower than 16 kilos, so high-quality monitor arms will simply help it.

Dell Professional 34 Plus USB-C connectivity

As I’ve talked about in previous critiques, connectivity is commonly not simply good to have however, moderately, your entire motive to purchase a monitor. And the Dell Professional 34 Plus USB-C has loads of connectivity.

The star of the present is the USB-C port. It helps USB-C with knowledge charges as much as 5Gbps, DisplayPort, and as much as 90 watts of USB Energy Supply. Whereas the info fee isn’t spectacular, the Dell Professional 34 Plus covers all of the fundamentals that must be anticipated from a contemporary USB-C monitor.

Further video connectivity consists of DisplayPort and HDMI. All video inputs can deal with the monitor’s most decision and refresh fee. DisplayPort-out shouldn’t be accessible, although, which is a bit disappointing for a monitor on this class.

The USB-C enter connects to 1 downstream USB-C port and three downstream USB-A ports. A few of these ports are present in a handy pop-out on the monitor’s chin, which makes it simpler to attach USB units. A USB-B enter is offered, too, and may hook up with the downstream USB ports instead of, or alongside, a USB-C gadget.

A gigabit Ethernet port is offered, which suggests the Dell Professional 34 Plus can prolong wired Ethernet to a related gadget. That’s helpful if you happen to’re connecting to a contemporary laptop computer (which, most definitely, lacks Ethernet) and are searching for a wired Ethernet connection.

Dell Professional 34 Plus USB-C menus and options

The Dell Professional 34 Plus USB-C’s choices are managed with a joystick on the rear proper flank. That’s typical for a monitor, although putting the joystick on this location on an ultrawide makes the management just a little onerous to achieve.

You may not want it, nonetheless, as a result of the Dell Professional 34 Plus is suitable with Dell’s Show and Peripheral Supervisor (DPPM). It’s a software program utility that may management most monitor options and picture high quality changes. Most rivals (together with Asus and BenQ) supply comparable choices, however Dell’s utility appears good and works properly. DPPM is suitable with Home windows 10/11 and MacOS, however not Linux.

Sadly, the Dell Professional 34 Plus doesn’t supply a terrific vary of picture high quality adjustment. It has only a handful of picture high quality presets and doesn’t present gamma and shade temperature presets that focus on particular values. Whereas I perceive the Dell Professional 34 Plus isn’t actually meant for homeowners choosy about picture high quality, I nonetheless really feel that, at this value, extra picture high quality changes must be anticipated.

The characteristic listing is a bit gentle, too. The monitor has a KVM swap but it surely doesn’t have built-in audio system, a tripod mount, or an ambient gentle sensor. The dearth of additional options feels stingy, given the MSRP. These searching for extra built-in performance would possibly think about the Dell Professional 34 Plus P3424WEB, a 34-inch ultrawide with digital camera, audio system, and comparable USB-C connectivity, which is bought at an MSRP of $819.99.

Dell Professional 34 Plus USB-C SDR picture high quality

The Dell Professional 34 Plus USB-C is a 34-inch ultrawide monitor with a 21:9 facet ratio, a show decision of 3440×1440, and a standard LCD-IPS panel.

The kind of panel is vital. Dell was the primary firm to promote displays with a brand new kind of IPS panel, known as IPS Black, that has improved distinction, and IPS Black is present in lots of its flagship displays.

The Professional 34 Plus USB-C doesn’t have this new kind of panel, nonetheless, which hampers its SDR picture high quality.

We begin with brightness, the place the Dell Professional 34 Plus USB-C gives a mid-pack most brightness of 327 nits. This stage of brightness is bigger than an OLED competitor, such because the MSI MPG 341C, and a few IPS-LCD displays, just like the BenQ PD3420Q.

Usually, the Dell Professional 34 Plus is vibrant sufficient to be used in a house or enterprise setting. Nevertheless, it might be brighter, as another displays present.

Subsequent up is distinction, the place the Dell Professional 34 Plus USB-C gives a distinction ratio of 1220:1 at 50 % of most brightness. That, as soon as once more, is a fantastic however not unbelievable outcome. The Dell Professional 34 Plus has a greater distinction ratio than the BenQ PD3420Q, but it surely’s inferior to the larger Dell Ultrasharp 4025QW, and clearly not in the identical league as MSI’s MPG 341C, which has an OLED panel.

That is the place the shortage of an IPS Black panel comes again to chew the Dell Professional 34 Plus USB-C. It merely lacks the distinction wanted to offer an immersive picture. It’s not horrible, however buyers can discover price-competitive displays which are significantly better.

Shade gamut is a weak point of the Dell Professional 34 Plus. It achieved a shade gamut that spanned one hundred pc of sRGB, 83 % of DCI-P3, and 78 % of AdobeRGB. That’s not dangerous, however because the graph reveals, it’s not aggressive with equally priced (and even cheaper) displays bought in 2025.

Shade accuracy is sweet, because the monitor achieved a median shade error beneath 2. Usually, shade errors shouldn’t be straightforward to note, and colours will seem like reasonable (or, at the least, true to their supply).

Nevertheless, the monitor noticed slight variants in gamma and shade temperature. I measured a shade temperature of 6700K, which is a bit cooler and extra sterile than the goal of 6500K. I additionally measured a gamma curve of two.3, which is a bit darker than the goal of two.2. These aren’t big swings, however I did discover the colour temperature noticeable. Additionally, the monitor lacks built-in changes that make this straightforward to repair (although software program calibration continues to be an possibility).

Sharpness is first rate. The monitor’s 3440×1440 decision works out to about 110 pixels per inch throughout the 34-inch, 21:9 facet ratio show. That’s not dangerous. Additionally, IPS-LCD displays shouldn’t have the sub-pixel quirks of OLED displays, which suggests the Dell Professional 34 Plus appears sharper than 34-inch OLEDs such because the MSI MPG 341C. However 3440×1440 decision isn’t all that spectacular in 2025, with 4K and 5K displays now available.

General, then, the Dell Professional 34 Plus USB-C’s picture high quality is a little bit of a bust. It’s okay. It does the job. And positively, it’s fantastic for the overall workplace productiveness for which this monitor is meant. Nonetheless, there are lots of equally priced displays that provide higher picture high quality at this value level.

Dell Professional 34 Plus USB-C HDR picture high quality

The Dell Professional 34 Plus USB-C doesn’t help HDR.

That’s principally fantastic for a monitor that targets workplace productiveness. Workplace productiveness apps don’t sometimes profit from HDR, and most don’t help it.

Nevertheless, OLED displays (that are bought at this value) do supply HDR, and a few are fairly good at it. So, in fact, they’re the higher alternative if HDR is vital to you.

Dell Professional 34 Plus USB-C movement efficiency

It shouldn’t come as a shock that the Dell Professional 34 Plus isn’t meant for gaming. Nevertheless, the monitor does present a refresh fee of as much as 100Hz, which is healthier than nothing. Moreover growing movement readability in video games, the elevated refresh fee additionally improves the readability of textual content and pictures as they scroll throughout the display.

Adaptive sync shouldn’t be supported, although, and the monitor quotes an unimpressive gray-to-gray pixel response time of 5 to eight milliseconds, relying on the mode. Movement blur stays apparent, and the monitor can’t sync with an enter gadget for easy body pacing.

Must you purchase the Dell Professional 34 Plus USB-C?

The Dell Professional 34 Plus USB-C P3425WE is a workmanlike monitor constructed for, properly, work. It doesn’t exit of its method to offer additional options or superior picture high quality and as a substitute narrows its focus to connectivity and sensible options, like a extremely adjustable stand.

I don’t begrudge Dell for that focus, however I do begrudge Dell for the value. Listed at an MSRP of $749.99, and at present bought for that value, the P3425WE turns into troublesome to suggest. It’s even $70 greater than the outgoing Dell P3424WE.

A part of me wonders if the bounce in value is the results of ongoing tariff issues. Or, maybe, Dell is just making an attempt to squeeze more money from enterprise and productivity-minded buyers keen to pay lots for a sensible show.

Both method, the value narrows the Dell Professional 34 Plus USB-C’s attraction. It’s a very good possibility for dwelling workplace buyers who need excellent connectivity, together with Ethernet and a number of downstream USB-A ports. When you’re extra involved about picture high quality and movement readability, although, it is best to think about OLED options with USB-C, just like the MSI MPG 341CQPX.
