The Dell Ultrasharp U2415 is an above-average IPS LCD monitor with a PC focused 1920x1200 resolution. Its wide viewing angles, taller aspect ratio (16:10) and highly ergonomic stand make it a great fit for office spaces, and its low input lag makes it a decent gaming choice as well. However, some aspects of its picture quality leave a bit to be desired, and it doesn't support modern features such as HDR or variable refresh rates.

The monitor is quite thin when viewed from the side, and sits quite close to a wall when used with the stand which is good.

7.5 Build Quality

The build quality of this Dell monitor is good. It is mostly made of plastic but feels sturdy, similar to other Ultrasharp monitors such as the Dell U2717H.

6.8

Picture Quality

The Dell Ultrasharp U2415 IPS monitor has a decent picture quality. The passable contrast ratio and poor black uniformity mean that it won't be the best monitor for darkroom use, but when set in a bright room, like an office space, the decent peak brightness and the way it deals with reflections mean the monitor will be much better suited for this kind of conditions. The viewing angles of the Dell U2415 are good and picture quality remains pretty good even if you see the monitor from the side or from the top, which is important if you have a dual monitor setup, where one monitor is set vertically.

The gray uniformity is great and dirty screen effect is really not an issue, no matter what kind of content you are viewing. The out of the box accuracy is very good and the coverage of the sRGB color space is excellent, making any SDR content looks like it was intended to be. Since this monitor is fairly standard, it does not have any more advanced features like HDR and local dimming.

The Dell Ultrasharp U2415 monitor's contrast ratio is not bad. With a contrast ratio just hovering about the 1000:1 mark, it is not in the top performer of the Dell IPS monitor, which hang around 1200:1, but is not far behind. Like with most other IPS monitor though, the U2415 is better suited for bright environments, as when used in a dark room, blacks look rather more like grays than really deeps black, which can be a bit disappointing for multimedia content.

Gray uniformity is great for the Dell U2415, which is good when displaying large areas of a uniform color, such as when gaming, browsing the web or watching YouTube. On the 50% gray test picture, the only visible issue is that the screen looks a bit darker on both sides near the edges and the bottom. Besides this, the screen looks pretty uniform which is great.

Looking at the 5% gray test picture, not much is noticeable, which is good and a sign the screen has a good uniformity. This is great for dark games at night.

4.5 Black Uniformity
Native Std. Dev.
:
3.009 %
Std. Dev. w/ L.D.
:
N/A

The black uniformity of the Dell Ultrasharp U2415 is poor so dark scenes appear blotchy when viewed in a dark room, such as gaming at night. Backlight bleed is visible near the corners and edges of the screen, which contributes significantly to these uniformity issues. This is less noticeable when in a bright room so if the monitor is used for office work, the poor black uniformity should not be too noticeable.

Out of the box, the accuracy is very good. The picture mode with the best accuracy was the 'Custom Color', which for most people, would be good "as is" not requiring any calibration, unless you are a professional who already uses other calibrated monitor, then a calibration could be useful.

Looking more in details, we see that the color are a bit oversaturated and the color temperature is a bit warmer than what we aim for usually, but overal the color dE is still under 3, which is very acceptable. As for the white balance, we still see the trend toward the warm side (a bit more red than necesary) but here again, with a dE under 3, it is still very good. Finally, looking at the gamma, we see the curve diverge a bit from the target curve, but not that much, as least not enought to creat problem, and as for the value, at 2.16, we are really not far from our 2.2 target.

After calibration, the accuracy of the Dell U2415 is excellent. Both the white balance dE and color dE are now under 1, which at this level of accuracy, imperfections are almost not noticeable. The colors are now tracking spot on their target, which before calibration were a bit oversaturated. As for the color temperature, we are now very close to our desired target of 6500K. Finally, for the gamma, the monitor's gamma curve is closer to our target curve, and the value (2.18) even closer to our 2.2 target.

8.8 SDR Color Gamut
sRGB xy

98.6 %
Adobe RGB xy

Very good SDR color gamut. The coverage of the almost universal s.RGB gamut is near perfect thanks to its factory calibration. Its ability to reproduce the Adobe RGB colorspace is however fairly limited, making it less useful for photo or print professionals which might use the larger gamut.

9.1 SDR Color Volume

The Dell U2415 does not produce color bleed.

7.5 Reflections

The reflection handling is good. It has a light-matte finish which produces diffuse reflections and reduces their intensity. It does also cause a light haze, but this shouldn't be an issue for most rooms. In a bright room though, reflections may be distracting.

7.1

Motion

Motion looks decent on the Dell Ultrasharp U2415, but not as good as on many gaming monitors. It has a fast pixel response time and a flicker-free backlight, which is good, but its very ordinary 60 Hz refresh rate and lack of variable refresh rate technology such as FreeSync will be limiting for some use cases like gaming.

Response Time Normal
Response Time Fast

Very good pixel response time, good enough for fast moving content like video games or sports. Most of the blur in the photo is due to 60 fps persistence which is a result of the Image Flicker; only a short ghosting trail can be seen following the moving logo, and very little color smearing, which is great. The 'Response Time Normal' setting is best; the 'Fast' setting adds noticeable overshoot and barely improves the rise time, and so is not recommended.

The monitor has a flicker-free backlight, which is great as it provides smoother motion when browsing the web or for office use. Unfortunately, it can't add optional 60 Hz BFI flicker to help clear up motion, but it's very rare for 60 Hz monitors to have BFI because 60 Hz flicker can be bothersome to people.

Like most monitors, the Dell Ultrasharp U2415 only has a 60 Hz refresh rate and no variable refresh rate feature. While this is good enough for most use cases, all would benefit from a higher refresh rate. Gaming, in particular, will be limited by the mediocre 60 Hz maximum refresh rate and lack of variable refresh rate technology such as FreeSync.

8.3

Inputs

One of the Dell U2415's standout features is its taller 16:10 aspect ratio, making it better than 1080p monitors for height-limited use cases such as web browsing, but still not as good as the many 27" 1440p monitors on the market. The monitor also has great low input lag, which will satisfy all but the most competitive gamers.

Non-native resolution tested: 1920 x 1080

Great low input lag, good enough for all but the most competitive gamers. This input lag is very similar to most other 60 Hz monitors like the Dell U2715H and HP V320; a higher refresh rate is almost required to lower the input lag any further.

7.4 Resolution and Size

Aspect Ratio : 16:10
Megapixels : 2.3 MP
Pixel Density : 94 PPI
Screen Diagonal : 24.0 inches
Screen Area : 260 sq inches

The Dell U2415 uses a taller 16:10 aspect ratio rather than the more common 16:9; this means that it has more vertical pixels (1200) than a normal 1080p monitor like the P2417H, despite having the same number of horizontal pixels (1920). This makes the monitor better for usage that benefits from the extra height, like web browsing, but only as good as a normal 1080p monitor for movie and TV watching. Unfortunately a 27" 1440p monitor would be better than the U2415 for almost all use cases.

The 3.5mm analog audio out jack is a fixed line out intended for speakers, so the monitor can't change its volume. It's possible to use it for headphones by using a computer to change the volume, but when used with headphones, there's a quiet hiss of static that is always present.

Both the HDMI ports support the MHL 2.0 standard for connecting mobile devices such as smartphones.

The lone USB port perpendicular to the back of the monitor supports the BC1.2 battery charging standard, and can provide up to 2A of charging current for supported devices.

Features

The Dell Ultrasharp U2415 has a few useful features like a built-in five USB port hub, and a DisplayPort Out for daisy chaining with other monitors, allowing multiple monitors to be fed from a single DisplayPort on a computer.

Additional Features

The monitor has a DisplayPort Out for daisy chaining with another monitor, allowing multiple monitors to be fed by one DisplayPort on a computer. This works by using the DisplayPort Multi-Stream Transport (MST) standard to send the video data for multiple monitors over a single cable. The U2415 receives the signal, then forwards the other video feeds out its DisplayPort Out to the other monitors in the chain.

The monitor also has a built-in USB hub with five USB 3.0 ports, one of which supports the BC1.2 battery charging standard for faster charging. The monitor also has a setting for leaving the USB ports powered even when the monitor is on standby, which is handy.

On-Screen Display (OSD)
Controls

The monitor uses an ordinary four button scheme to control the OSD; however, the buttons are touch buttons, which are nicer to press but can take some getting used to at first.

7.4 Mixed Usage

The Dell Ultrasharp U2415 is a decent monitor for a mixed usage. Its wide viewing angle and great ergonomics make it a particularly good fit for office use, and its low input lag makes it a decent gaming choice as it feels responsive. Unfortunately, it lacks modern features like HDR, and its picture quality in darker environments leaves a lot to be desired.

7.7 Office

Good monitor for usage in an office. The taller than average 16:10 aspect ratio can be quite useful for productive tasks, and its overall feature set is well suited for office-oriented tasks. Its wide viewing angle and easy position adjustments make it simple to share with others, and its 1200p resolution provides decent screen real-estate. The picture quality is only decent, but many of the dark scene flaws aren't visible in a bright office.

7.7 Gaming

Good monitor for gaming. With a low input lag of 9.1 ms, the great majority of users won't notice any delay following their mouse movements. However, the Dell U2415 doesn't have more advanced gaming feature such as a higher refresh rate to feel more responsive, or variable refresh rate to reduce screen tearing. It also lacks black frame insertion capabilities which can greatly enhance motion.

7.1 Multimedia

Decent monitor for consuming media. While the Dell U2415 does not produce a very high contrast, its factory calibration makes it quite accurate out of the box, allowing you to enjoy natural-looking content. Unfortunately, it lacks supports for wider color gamuts or HDR, and it doesn't have any local dimming feature. Its PC-oriented resolution might be bothersome as well, since full-screen 16:9 content will still feature letterboxing.

7.2 Media Creation

Average monitor for media creation. The color accuracy and wide viewing angles are good features for media creators, but its lack of support for professionally oriented color spaces such as Adobe RGB and DCI-P3 makes it a bit limited. Some might also find its resolution to be a bit low for modern photos or video projects which feature high-resolution content.

5.4 HDR Gaming

HDR is not supported. Lack of HDR is common for monitors within this budget, as only a few high-end monitors (such as the CHG70) support HDR.
