The Dell Ultrasharp U3417W is an above-average curved ultrawide IPS LCD monitor with a high 3440x1440 resolution. It gets brighter than average and comes with a factory calibration. It has a very wide viewing angle and produces a low amount of input lag, which is good for gaming. Unfortunately, its low contrast and uneven blacks result in only an average picture quality and it lacks motion-enhancing features such as a high refresh rate or black frame insertion.

Design

Score components: Subjectively assigned
Dell U3417W Design Picture
Curved : Yes
Curve radius : 1900R
Weight (without stand) : 16.8lbs (7.6 kg)
Weight (with stand) : 22.0lbs (10.0 kg)

The design of the Dell U3417W is excellent. The width of the screen stands out and the curved screen looks good. The stand is fairly heavy and results in a stable monitor despite the small footprint. Like other ultrawide monitors, it isn't possible to rotate the monitor to display a portrait image. The rear also looks good, and there is a hole in the stand to route cables through and reduce clutter.  The build quality is also great, and shouldn't cause any issues.

Stand

Width : 13.4" (34.1 cm)
Depth : 8.9" (22.5 cm)

The stand has a fairly small footprint, but still supports the monitor well and feels very stable. It has the typical Dell minimalistic design, which is good.

4.7 Ergonomics
What it is: How much the position of the screen can be adjusted to match the viewing preference of the user.
When it matters: All usages, but especially office and gaming use.

Height Adjustment : 4.4" (11.3 cm)
Switch portrait/landscape : No
Swivel Range : N/A
Tilt Range : -20° to 5°

Like most ultrawide monitors, ergonomic adjustments are limited. The only options are to adjust the height by 4.4" or to tilt the monitor. This limited range of adjustments can make it a bit more difficult to find a comfortable viewing position.

Back

Wall Mount : VESA 100x100

The rear of the monitor looks clean and minimal. A hole at the back of the stand provides space for some cable management. All of the inputs are located on the bottom and directed down.

Borders

Borders : 0.4" (1.0 cm)

The borders of the Dell Ultrasharp U3417W are quite thin and look good. They are fairly basic, made of plastic.

Thickness

Thickness (with stand) : 7.9" (20.0 cm)
Thickness (without stand) : 4.0" (10.2 cm)

The Dell U3417W monitor appears quite thick when viewed from the side due to the curve of the screen. It can sit quite close to a wall though, which is good.

What it is: How well built and sturdy the monitor is, and how good the materials used to build it are.
When it matters: All usages.

Dell U3417W Build Quality picture

The build quality of this Dell Ultrasharp U3417W monitor is great. The parts feel high quality and well constructed. It is unlikely to present any issues in normal use.

The Dell Ultrasharp U3417W monitor has a decent picture quality. The sub-standard contrast ratio and poor black uniformity mean that this monitor won't be the best suited for a dark room use, as black look gray and give a washed out look to dark content. Fortunately, as with most IPS monitor, when set in a brighter environment, the picture quality is much better. Viewing angles are very good and whether you look at the monitor from the side or the top, the picture quality remains pretty good.

Gray uniformity is also good and multimedia content is not affected by any dirty screen effect whatsoever. The Dell U3417W is a very accurate monitor out of the box (calibration-wise) and covers almost completely the sRGB color space. Finally, the monitor does not have more advanced features like local dimming or HDR support.

The Dell Ultrasharp U3417W has a sub-standard native contrast ratio and as a result, it is not best suited for use in a dark environment since black tends to look more grayish than really deep blacks. This is particularly noticeable when playing video games in a dark room, as it gives a washed out look to most dark video cutscenes. For this reason, this monitor is best suited for well-lit room, as most other IPS monitors.

Note that the 908:1 contrast ratio is measured with the 'Uniformity compensation' set to 'Off'. We found out that when set to 'Calibrated', the contrast ratio was only of 554:1, and since we did not find any striking advantage when this option was set to 'Calibrated', we decided to leave it to 'Off'.

Very good SDR peak brightness. The Dell 3417W has no issue getting bright enough to be usable in almost all viewing environments. Unfortunately, most picture modes come with the "Uniformity Compensation" feature enabled which reduced the brightness of our units to a mere 200 cd/m2. To achieve the higher luminance level, this setting must be disabled.

Good horizontal viewing angle. As is typical of IPS-type LCD monitors, the Dell Ultrasharp U3417W's black level does not rise significantly when the monitor is used at an angle. Its colors remain decently accurate and it doesn't lose most of its brightness until it is viewed at a fairly steep 50-degree angle.

The Dell U3417W has a great gray uniformity, as seen on both the 50% and 5% gray test pictures. This is great for looking at large areas with uniform colors, such as browsing the web or watching YouTube videos. The only issues we can really notice on the 50% gray test picture are that the 2 sides of the screen look a bit darker than the center, but this is not very noticeable in use.

We tested the monitor with both the 'Uniformity compensation' set to 'Off' and to 'Calibrated'. We found out that the 50% gray uniformity was a bit better with the 'Uniformity compensation' set to 'Calibrated' (see test picture here), but it was the only place that this feature gave a better score. Overall, the monitor was better with the feature turned off, so we suggest you leave it set to 'Off'. In any case, you can try and see it for yourself if you feel that it can help, as it may be different between units.

The black uniformity is poor. Backlight bleed is visible near all 4 corners, with the lower left corner being the worse and it is a noticeable in a dark room. Some faint vertical lines are also visible, but luckily those lines are not really noticeable when the monitor is displaying normal content.

Once again here we did test with and without the 'Uniformity compensation' feature. The black uniformity was actually better when the feature was turned off.

The accuracy of the Dell U3417W 'out of the box' is great. We found the 'Multimedia' picture mode to be the most accurate of the picture mode available, but both the 'Standard' and 'custom color' were pretty close too, so any of the 3 picture modes could have been used and the accuracy would not be too bad.

Overall, when on the 'Multimedia' picture mode, the white balance and color dE are both under 3, which only people like professional that are used to work with calibrated monitors could really notice any problem here (most people would find it fine for sure). The color temperature is also very close to our 6500K target, and for the gamma, both the curve and value are really close to our target, which overall is great for most PC use and gaming.

After calibration, the Dell 3417W accuracy is excellent. The calibration was done on the 'Custom Color' picture mode, which was already good out of the box, but the calibration helped to fix the minor issues. Both the white balance dE and color dE were brought down under 1, which is under what most people would notice any irregularities. The colors are a bit more precise than before calibration, as they are now mostly on targets, as before calibration, the red, green and yellow were a bit over-saturated.

When it matters: Details in shadows, sky and skin tones. Matters more for HDR content.
Score components: Subjectively assigned
Dell U3417W Gradient Picture
Color Depth
What it is: Number of bits per pixel to represent a specific color. Note: we consider 8-bit with dithering to be equivalent to 10-bit, as long as the 10-bit gradient looks smooth.
When it matters: HDR content like HDR video games or HDR UHD movies. Won't matter for regular Blu-ray movies, SDR video game or desktop environment content displayed from a Windows PC. Those are limited to 8-bit color.
Good value: 10-bit.
Noticeable difference: 1 bit.
:
8 Bit

The Dell U3417W has a very good performance when displaying our gradient test image. 8-bit banding is visible, but this is normal since it is an 8-bit monitor. Besides this, the gradient looks smooth and without any striking color banding. Overall, this is pretty good for a PC monitor.

10.0 Color Bleed

The Dell U3417W does not produce a noticeable amount of color bleed. It is well suited for people that are particularly sensitive to it, or for artists that often work with large uniformly colored elements or grids.

8.0 Reflections
What it is: How much light is reflected by the TV.
When it matters: Bright rooms.
Score components: Subjectively assigned
Dell U3417W Average room Dell U3417W Average room off picture Dell U3417W Bright room off picture

The reflection handling is great. The curve results in some distortion of the reflections, which may be an advantage as it tends to diffuse point sources across the screen and reduce their intensity. The light-matte finish helps diffuse them further, so this should be great even in a fairly bright room.

7.1

Motion

Score components:

Motion looks decent on the Dell Ultrasharp U3417W, but not as good as on many gaming monitors such as the Samsung CHG90. The monitor has a fast pixel response time and a flicker-free backlight, which is great, but its mediocre fixed 60 Hz refresh rate is quite limiting for gaming and doesn't feel quite as smooth as some higher frame rate monitors. Overall though, for uses which don't require a high fps, it performs well.

8.4 Motion Blur
What it is: The performance of the pixel response time. Poor response time causes trails to follow moving objects. Response time is one of a few sources of motion blur.
When it matters: When there's fast movement on screen, such as during video games and sports.
Score components:

When it matters: When adjusting the monitor's settings to get the least possible motion blur.
:
Normal

Response Time Normal
Response Time Fast

Very good pixel response time, which is great for watching fast moving content such as playing video games or watching sports. Most of the blur in the photo is due to 60 Hz persistence, which is a result of the relatively long 16.6ms frame time. There is only a very short blur following the moving logo, which is great. The 'Response Time Normal' setting was the fastest; the 'Fast' setting wasn't any faster and added a lot of bothersome overshoot (visible as an inverse ghosting following moving objects), so it's not recommended. Overall, the response time is similar to many other IPS monitors like the Dell U2717D, but not as good as some gaming IPS monitors like the Acer Predator XB271HU.

7.5 Image Flicker
What it is: Luminosity pattern when displaying images
When it matters: Nearly all the time during PC monitor use, but especially during fast movement such as video games

The Dell 3417W has a flicker-free backlight which is great as it produces comfortable, smooth motion. The backlight has a slight 60 Hz wobble, but the wobble isn't deep enough to be noticeable. Unfortunately, the monitor doesn't have a black frame insertion feature. This is disappointing because 60 Hz flicker can be useful to clear up fast motion such as when playing fighting or shooting games. It is very rare for a 60 Hz monitor to have BFI because many people find 60 Hz flicker bothersome, so this isn't too bad.

6.7 Refresh Rate
What it is: How frequently the monitor can refresh and show new frames, and whether it can vary its refresh rate in real time using technologies like G-sync and FreeSync.
When it matters: Mostly for gaming, but does provide a little better motion during normal usage.

The monitor only has a very common 60 Hz refresh rate, without any variable refresh rate feature like FreeSync. While this is good enough for most usages, they all would benefit a little from a higher refresh rate. Gaming, in particular, will be disadvantaged by the mediocre refresh rate and lack of VRR.

8.3

Inputs

Score components:

The Dell Ultrasharp U3417W has an ultrawide 21:9 aspect ratio, a large 34" panel and a sharp 1440p resolution; all of which will impress during all usages. The monitor also has good low input lag which will please all but the most competitive gamers, but, unfortunately, a bug causes the monitor to skip a frame every ~21.6 seconds, which means the input lag rises and falls during that 21.6 second cycle.

7.9 Input Lag

Non-native resolution tested: 2560 x 1080

Good low input lag, which should please all but the most competitive gamers. Unfortunately, the input lag varies considerably over time; the monitor skips a frame every ~21.6 seconds, so the input lag rises slowly over 21.6 seconds then falls back down to its lowest value. This varying input lag is subtle and shouldn't be noticeable to most people, but it does raise the average input lag to 17.2 ms; without the bug the input lag would likely be ~10 ms like the Dell U2715H.

8.8 Resolution and Size
What it is: The number of pixels the monitor can display, and the surface area of its screen.
When it matters: All usages, but especially for office and media editing.
Score components:
Native Resolution : UWQHD, 3440 x 1440
Aspect Ratio : 21:9
Megapixels : 5.0 MP
Pixel Density : 109 PPI
Screen Diagonal : 34.1 inches
Screen Area : 415 sq inches

The Dell Ultrasharp U3417W monitor has an ultrawide 21:9 aspect ratio, a large 34" size and a sharp 1440p resolution; all of which are great for all usages. The ultrawide aspect ratio, in particular, is great for providing immersion while gaming, or for using two windows side by side during office use.

The 3.5mm analog line out can be used for headphones, but the volume can't be adjusted by the monitor itself.

There are also two USB Type-B hub inputs, either of which can be used to connect the four USB 3.0 inputs to a computer. This is explained in more detail in the Additional Features section below. Two of the three USB 3.0 inputs support the USB BC 1.2 charging standard, which allows them to provide more amps of current when charging.

Features

The Dell Ultrasharp U3417W has all the standard features of a monitor, like adjustable image and overdrive settings, but the monitor also has a raft of features not found on most other monitors such as built-in speakers and a DisplayPort Out for daisy chaining with another monitor. The monitor also has several features that make it useful as a shared display for two computers, such as picture-in-picture and picture-beside-picture modes, and USB port switching. The monitor also has a 'Uniformity Calibration' setting that we recommend turning off because it significantly hurts the monitor's peak brightness and contrast.

Additional Features
What it is: Additional features found on the monitor
Score components:
Speakers
What it is: Whether or not the monitor features standalone speakers.
When it matters: When using your computer without headphones or a dedicated pair of speakers.
:
Yes
HDR10 : No

The Dell U3417W has speakers that can get decently loud, but not nearly as loud as headphones or dedicated speakers.

There is a DisplayPort Out on the back of the monitor for daisy chaining, meaning another monitor can be connected directly to the U3417W, so both monitors can be fed by one DisplayPort on a computer. How this works is that the computer uses DisplayPort Multi-Stream Transport to send two DisplayPort signals over one cable. These two video feeds are input into the monitor, which then sends one of the feeds its DisplayPort Out to a second monitor, allowing dual monitors using only one DisplayPort.

The monitor also has many features that make it useful as a shared display between two sources. It has both picture-in-picture (PIP) and picture-beside-picture (PBP) modes, each with a few sub modes; for example, the PBP Aspect Ratio mode shows both inputs side by side but preserves their aspect ratio, even if their aspect ratio is different. The monitor's EDID even has a (1720x1440) entry so an input can fully cover half the screen in PBP mode.

Another useful screen sharing feature is that the monitor's four USB ports can be shared between two computers. The USB ports can be fed by either one of the monitor's two USB Type-B hub inputs, and the hub inputs can be plugged into two different computers. Each hub input can be tied to a video input, such that when the DisplayPort is the active input the USB ports are fed by hub input 1, and when HDMI 1 is the active input the USB ports are fed by hub input 2, for example. This allows the four USB ports to be shared between two computers.

On-Screen Display (OSD)
Controls
Dell U3417W Controls picture

The monitor has a typical five button control scheme: one power button and four buttons to control the OSD. The buttons provide good tactile feedback but are so small and stiff that they can hurt your fingers when used a lot.

Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

The Dell U3417W is an Ultrawide monitor with an office and productivity focus. While the high resolution and large size do make it great for this use, it comes at a high price and for other uses, it isn't as good of a fit.

Samsung CF791

If you've got a large room with wide seating, then the Dell U3417W is a better choice, but if you are interested in gaming in a dark room while sitting directly in front, then the Samsung CF791 is better. The Dell U3417W has an IPS panel, giving you better viewing angles whereas the CF791 has a slight better refresh rate and a slightly faster response time resulting in clearer motion.

Samsung CHG90

The Samsung CHG90 is a bit better than the Dell U3417W, unless you need wider viewing angles. The Samsung CHG90 supports HDR and has much better dark room performance thanks to the higher native contrast. The CHG90 is better for gamers than the U3417W, as it has much less input lag and a faster refresh rate, so motion looks smoother with less blur. The picture quality of the Dell U3417W doesn't degrade when viewed at an angle.

LG 34UC79G-B

The LG 34UC79G-B is a bit better than the Dell U3417W. The 34UC79G-B has a much higher native refresh rate, and much lower input lag, as well as FreeSync support for gaming. Motion looks much better on the LG as it can introduce backlight flicker to reduce motion blur. While both screens are the same size, the Dell U3417W has a higher native resolution, so you can see more fine details.

LG 43UD79

The Dell U3417W is a bit better than the LG 43UD79. The U3417W is a bit brighter and has more vibrant colors due to the better color volume. The U3417W has better ergonomics and it is easier to adjust to a comfortable position, whereas the LG 43UD79 has very limited adjustments. It has lower input lag and the larger screen provides more screen real estate, good for productivity.

Dell U2715H

The Dell U2715H is a bit better than the Dell U3417W. The U2715H has better ergonomics and is easier to place in an optimal viewing position. The U2715H is better for gamers as it has much lower input lag. The Dell U3417W is a larger screen with a widescreen aspect ratio and higher native resolution, so it is easier to multitask.

ASUS ROG PG348Q

The ASUS ROG Swift PG348Q is better than the Dell U3417W. The PG348Q has much better motion handling, with a faster response time and higher refresh rate, as well as NVIDIA G-Sync VRR support. The ASUS also has much lower input lag, making it a much better gaming monitor overall. The Asus also has a better stand that can also swivel, great for sharing work with someone else.

Acer Predator XB271HU

The Acer Predator XB271HU is a gaming oriented monitor with a 144Hz refresh rate and 1440p resolution. It feels very responsive due to the low input lag and excellent motion handling and has a great stand, which makes it easy to share graphics with coworkers. It isn't as accurate out of the box as the Dell 3417W and does have a lower resolution, but is a better choice at a similar price point.

  • 30% Multimedia
  • 25% Gaming
  • 10% Media Creation
  • 5% HDR Gaming
The Dell Ultrasharp U3417W does a decent job for a mixed usage. Its high resolution and large size make it a great choice for multitasking, and its high brightness and large viewing angles mean it will fit most environments without issue. Unfortunately, its uneven blacks and low contrast reduce its picture quality.
Better than average monitor for usage in an office. While its stand doesn't offer much flexibility in movement, its very large size means you're rarely going to move the Dell 3417W. Its wide viewing angle and large virtual workspace make it very useful for productive tasks since you can have many windows open at usable sizes around the screen.
Average monitor for gaming. While it doesn't offer high refresh rates, the monitor's ultrawide aspect ratio makes for a very immersive gaming experience. Unfortunately, it also lacks features such as variable refresh rate and BFI which can greatly improve the motion quality.
Passable monitor for consuming a variety of media. The Dell 3417W's 21:9 resolution allows it to display most theatrical content without black bars, making it quite immersive. Unfortunately, it lacks support for wider gamuts or HDR. Its uniformity issues and low overall contrast also mean that its picture won't look exceptional in a dark room.
The Dell Ultrasharp U3417W is a decent choice for media creation. It comes with a factory calibration with serviceable accuracy, so less demanding workloads can be done straight out of the box. However, its limited coverage of larger color spaces such as Adobe RGB and DCI-P3 limit its usefulness in a professional environment.
HDR is not supported, which is normal as HDR support for monitors is very limited. For a monitor with support, see the Samsung CHG90.
