The Dell S2417DG is a good 1440p gaming monitor with G-Sync variable refresh rate support. It has a TN panel with mediocre picture quality due to the poor native contrast ratio so blacks appear gray in a dark room, and the image also rapidly loses accuracy when viewed at an angle. For gamers though, it has a high 144Hz refresh rate and feels very responsive due to the low input lag. It also has a fast response time, so fast paced motion only has a short blur trail.

Stand
Width
:
9.5" (24.1 cm)
Depth
:
7.1" (18.0 cm)

The stand of the Dell Gaming S2417DG is plastic and very similar to the S2716DG. It supports the monitor well which is great.

Back
Wall Mount : VESA 100x100

The back of the monitor is very plain. It is made out of plastic that is very glossy and reflective. Because of that, it will show the marks of where you touched it.

Borders
Borders
:
0.3" (0.8 cm)

The borders of the monitor are very similar to the ones of the S2716DG. They are not thick and they look good. There is a small gap that runs along the border that also serves as a cooling vent of the monitor. And there is also some gap between the bezel and the start of the pixels.

Thickness
Thickness (with stand)
:
5.7" (14.5 cm)
Thickness (without stand)
:
2.2" (5.6 cm)

The thickness of the Dell S2417DG is average and will not protrude too much when VESA mounted. The stand footprint is small and allows the monitor to be placed close to the wall if necessary.

7.5 Build Quality

The build quality is ok. There are no gaps and the monitor looks sturdy and sound. You should not expect any issues while using it.

Controls

There are buttons on the underside of the monitor. They are shallow and can be hard to press at times, and can hurt your fingers because they're small and stiff.

In The Box

  • Manual and drivers
  • DisplayPort cable
  • USB cable
  • Power cable

Height Adjustment
:

Switch portrait/landscape : Yes
Swivel Range : -45° to 45°
Tilt Range : -17.5° to 10°

The range of ergonomic adjustments is great, so you can adjust it in pretty much any position you like to make it comfortable for your working preferences.

5.2 Contrast
Native Contrast
:
620 : 1
Contrast with local dimming
:
N/A

The contrast of this monitor is disappointing. It is currently the lowest one we have measured. The monitor is not well suited for dim environments as blacks look washed out, and the image is not vibrant. It is very similar to its big sister, the S2716DG.

:
0.854 %
5% DSE
:
0.072 %

The gray uniformity is very good. The Dell S2417DG has very good uniformity in darker shades of gray and looses some of its accuracy in lighter shades. In the 50% gray image, the edges are slightly darker than the center but this a result of the poor vertical viewing angle rather than a gray uniformity issue. This might bother a little those who want to use it for web browsing, and sit too close to the monitor.

The horizontal viewing angle is disappointing. Even slight deviations from the middle angle and the monitor loses color accuracy, blacks wash out, and brightness fades. Those viewing it from the side will not have the same viewing experience to those who look straight up front. This is a typical issue with most TN monitors. It is more apparent, however, the closer you sit to the monitor and the bigger the monitor size.

4.8 Black Uniformity

The black uniformity is bad. Clouding is all over the screen and blacks look gray. The lighter artifact in the top half may be some damage to our unit, either during shipping or because of our mishandling. It is not, however, very noticeable in normal content.

Response Time Normal
Response Time Fast

The monitor has an excellent fast response time. When set to Fast overdrive mode it adds a lot of overshoot, so Normal mode is preferred.

9.4 Image Flicker

PWM Dimming Frequency
:
0 Hz
Black Frame Insertion (BFI)
:
Yes
BFI Maximum Frequency
:
120 Hz
BFI Minimum Frequency
:

The Dell S2417 has a flicker-free backlight and this is great. However, it also has the ability to add flicker so as to remove blur. There is also a Pulse Width option that can change the pulse width of the flicker, and can make motion even clearer. This, however, sacrifices some brightness. Unfortunately, when you activate ULMB it adds some overshoot to pixel transitions, that is seen as inverted ghosts following the pattern in the photo. In normal usage this should not be noticeable.

It should be noted that BFI is only supported on DP and at 85, 100 or 120Hz.

BFI frequency tested: 120 Hz

The monitor has an excellent low input lag in native 1440p resolution. However, when sent a resolution other than 1440p, it does not have a 144 Hz refresh rate.

We also couldn't get any non-native resolutions to work over DisplayPort, hence the N/A in the score (even though the manual states that the display supports resolutions like 1024x768, 800x600 and 720x480).

The vertical viewing angle is mediocre. This is mainly due to the monitor keeping a good color and black accuracy and good brightness levels when viewed from above.

8.3 Gradient

The out of the box colors of this monitor are disappointing. Even at the most accurate mode of Standard the white balance dE was well above our threshold of 3 and the Color dE was almost just as bad. The threshold of 3 is where we believe most people will start noticing the inaccuracies.

Gamma was well below 2.2 and shades looked very dark and the color temperature was too warm, with yellowish and reddish tones.

The SDR color volume is good. Almost 90.1% of the s.RGB color volume is covered mainly due to good very good color space coverage. However, due to the lacking coverage of the Adobe RGB color space, the monitor is unable to cover the Adobe RGB color volume and in conjunction with the poor contrast ratio, it fails to deliver very dark tones.

7.5 Reflections

The reflection handing is good. The monitor uses its light-matte finish to diffuse reflections across the screen, which reduces their intensity while producing some haze. In a very bright room, this might be bothersome to some people but in an average room, it should be ok.

9.9 Color Bleed

7.5 Mixed Usage

The Dell S2417DG is a good monitor for mixed usage. It is very ergonomic and can be positioned to suit any taste and has very good gaming features. It does suffer however from narrow viewing angles as most TN monitors, and its picture quality does not make it a good choice for movie watching.

7.4 Office

The Dell S2417DG is decent for office use. The high brightness capability makes it a good choice for bright lit offices and the ergonomic stand will be well appreciated by the user. Unfortunately, the poor viewing angles will not allow you to work comfortably with other colleagues without having to swivel the monitor.

8.5 Gaming

This is an excellent monitor for gaming. It has VRR support through the G-Sync technology that will help avoid tearing when playing this high graphics demanding game. Also, the BFI feature will help clear the motion. The low input lag, the 144 Hz refresh rate and the 1440p resolution, are all essential factors to gamers and this monitor scores well. So most people will enjoy using it for gaming.

7.2 Multimedia

The S2417DG is a decent monitor for use with media. Although the resolution is good at 1440p and the input lag is low, watching movies in darker environments does not look good due to the low contrast ratio. One other slightly disturbing factor is the limited viewing angle which requires you to sit right in front of the monitor to get an accurate picture. Overall it should not be your first option when choosing a monitor for multimedia usage.

7.4 Media Creation

Decent performance of this monitor in media creation. It has a great resolution, low input lag, excellent refresh rate and good ergonomics that are a big plus while working in video editing or touching up pictures. However, the lack of good viewing angles is hurting the performance of this monitor.

5.6 HDR Gaming

Unfortunately, the Dell S2417DG does not support HDR like the Samsung CHG70.
