Dell UltraSharp 34 Curved U3425WE Monitor Review: Jack Of All Trades

Productivity and content creation are a core focus of this particular monitor, and that it does very well. To test Dell’s claims of maximizing eye-comfort, I set out to make this my main work machine for an extended period of time to see how my eyes reacted. Starting with the immersive WQHD resolution and 34-inch size is a great step, with my entire workflow layout spread out in front of me.

Panel quality with its IPS Black technology is excellent. Text is clear, sharp, and colors look beautifully saturated along with this display’s 2000:1 contrast ratio. Brightness was good with display HDR600, and the light sensor worked in the background to keep the experience consistent across a variety of room lighting conditions. 

We easily connected to the 2019 Apple Mac Pro with its Thunderbolt cable for the display connection, and to a PC via its DisplayPort cable. A major consideration professionals will always appreciate is richness of connectivity options, and in this regard the UltraSharp 34 U3425WE delivers in spades. The ability to use Thunderbolt 4, USB A / C, Ethernet and various other display connectivity is essential for many use cases. 

video editing

Video editing was also very enjoyable on this monitor, once again owing to its expansive 34-inch panel size and high-quality display. Colors appeared accurate and vibrant and with good levels of contrast out of the box, without additional calibration. Of course, we still wanted to calibrate this display for testing and to quantify some of its capabilities.

displaycal

Using DisplayCAL with a Calibrite Color Checker to measure the characteristics of the display provided excellent results. Dell claims Delta E is less than 2 on average, and the tests provided an excellent result of 0.14 average with a maximum shift of 2.84. Gamut coverage is also very good, with near 100% sRBG coverage and over 91% actual measured coverage of DCI P3.

In real world use, we also paid special attention to the eye-comfort levels to see if we noticed any difference from our Apple Studio Display when working. The Dell U3425WE did seem easier on the eyes, without any noticeable strain even after many hours of use. The ComfortView technology also worked behind the scenes to keep blue light emissions low. Blue light will be less than 35% according to Dell, a marked improvement for the usual 50% or so experienced on other monitors not tuned for reduced blue light emissions.

The ambient light sensor also seemed to do its job very well, adjusting brightness as needed when we turned off some office lights. DisplayCAL’s uniformity test (above) proved the display has some excellent brightness characteristics across the entire panel, tested on 5×5 grids to break the panel down into 25 individual zones. As you can see, uniformity is essentially perfect — all of the 25 zones are within expected tolerances, as represented by the green outlines in the image above. Displaycal will highlight a non-uniform zone with amber, when it’s only slightly out of spec, and red, if uniformity is particularly bad. Uniformity is a non-issue, at least with our particular sample, which was near perfect. Coupled with the 120Hz refresh rate, fluid and smooth on both Mac and PC as well.

The Dell U3425WE also comes with built-in speakers, which proved to be rather enjoyable. While typing and writing, we played classical music such as Bach through the speakers, and they provided a clear, nicely full-bodied sound. Editing video also proved successful with this setup, and they were adequate for most tasks. While some users may prefer to use discrete external speakers for higher audio fidelity, the ones included in this Dell display will surely do the job some folks.

Adobe Photoshop was a pleasure to use on this monitor. Once again, the expansive panel size and relatively high resolution made it a great companion. Color accuracy and vibrancy are the main attractions here, with the 2000:1 contrast ratio helping with editing photos. While this is a matte display, occasionally you can get some minor glare from brighter light sources as seen in the above photo on the top left of the panel, but that is as expected. The monitor reacts very well to light, especially within a normal brightness range.

For use cases where you’ll want two systems connected, KVM functionality is built in and can be used over a network or the traditional way with discrete cables. We connected a Mac to the Thunderbolt display connection, and a gaming PC to the DisplayPort. Both functioned perfectly, and it was easy to switch inputs with the joystick and menu system as needed. On the Mac, the volume control wasn’t available directly as it would normally be on the Apple Studio Display, but there are some work arounds for that option. Volume control via the keyboard worked fine with the PC, however. This is true of most monitors and Apple Mac systems when using HDMI or Thunderbolt, so it is not a reflection on the Dell UltraSharp 34’s capabilities itself. 

viewing angle
Excellent viewing angles make for a flexible, and comfortable, experience. 

Excellent viewing angles add to the high-quality experience of this panel, with 178 degrees vertical and horizontal. This delivered real-world comfortable visibility in many lightning and seating conditions, regardless of more obtuse angles. We don’t all always have perfect posture, and remain dead center of our displays, so maintaining accuracy at wider viewing angles is definitely helpful, and one of the main advantages of IPS display technology.

How Is The Dell UltraSharp 34 Curved Thunderbolt Hub U3425WE Monitor For Gaming?

Gaming may not be the apparent as the target for this monito, but it does pack an impressive 120Hz refresh rate, which combines for an excellent gaming experience coupled with its immersive 34-inch size. 

Response time is a minimum of 5 ms for gray-to-gray, which is good for productivity, and still falls within a decent range for gaming. The fastest gaming monitors on the planet will have even faster response times that eclipse the Dell U3425WE, but this display strikes a good compromise for the type of panel that it is. Plus, you’re still getting the same eye-comfort benefits when gaming too, which is sure to be a relief on your circadian rhythms after a long night of gaming fun.

Gaming was an absolute joy, with Ratchet and Clank showing the vibrant and colorful image reproduction that this monitor has. Its DisplayHDR600 certification will fall short of the HDR capabilities of other high-end panels geared for gaming, but it proved to deliver a wonderfully rich output with excellent contrast and brightness. 

Motion was smooth, with no ghosting or other issues, and response time proved more than adequate for this single player game. The U3425WE’s IPS Black technology did a great job in keeping darker scenes clear and with a good balance in requisite areas. While not as deep as OLED panels, black levels and color vibrancy were excellent. 


The integrated speakers of this display provided to be good for gaming, too. While not on the level of a good soundbar or separate audio system, it can do the job for those just wanting clear, balanced sound from the monitor itself.
