The Dell UltraSharp U2717D is a decent 27 inch IPS-type LCD monitor with great ergonomics and a wide viewing angle. Its picture quality is decent, and it gets bright enough to suit most environments. Unfortunately, though, it isn't the best monitor for gaming due to its relatively high input lag at its native resolution. Furthermore, its uneven blacks with visible backlight bleed leave a lot to be desired.

Our Verdict

7.1 Mixed Usage

The Dell UltraSharp U2717D is a decent monitor for a mixed usage. It has a wide viewing angle which makes it easy to enjoy from many viewing positions, and its screen is quite bright. Unfortunately, its uneven blacks hinder its picture quality, and its higher than average input lag makes it less desirable for gaming.

Pros
  • Wide viewing angle
  • Very flexible stand
Cons
  • Uneven, cloudy blacks with visible backlight bleed
  • Higher than average input lag
7.4 Office

Good monitor for usage in an office. Its highly adjustable stand makes it easy to set up in a position comfortable for long hours of work. Its pivot feature combined with its wide viewing angles also make it easy to share with neighboring colleagues. It does get decently bright, but its handling of reflections could be a little better.

7.3 Gaming

Passable monitor for playing video games. While it handles motion blur decently, the Dell U2717D's input lag is quite high when used in its native resolution. This is less of an issue for people that use wireless controllers instead of a mouse and keyboard, but the monitor also lacks more advanced features like a high, variable refresh rate.

6.9 Multimedia

The monitor does about average for multimedia consumption. Its picture quality is decent, but its less than stellar blacks leave a lot to be desired. Unfortunately, it also lacks any advanced features such as support for HDR and wider color gamuts.

7.1 Media Creation

Decent monitor for media creation. The Dell U2717D's decent brightness and acceptable color accuracy make it suitable for more casual production of movies of photography. Its decently high resolution is also quite useful. Unfortunately, its relatively low contrast and lack of support for wider color gamuts like DCI-P3 might make it less attractive to professionals.

5.1 HDR Gaming

HDR is not supported, which is common as it is relatively new to monitors. For an HDR model, see the Samsung CHG70.

The design of the Dell U2717D is almost the same as Dell's other monitors in the Ultrasharp range, such as the U2715H. It has a rectangular stand with a small footprint, which feels very stable. It also has a good range of ergonomic adjustments, so finding a comfortable viewing position is easy. Overall, the monitor looks professional and feels high quality.

The gray uniformity is impressive on this Dell UltraSharp U2717D monitor. On the 5% gray uniformity test picture, the most noticeable issues are the darker areas near the edges of the screen, which may be slightly visible when watching movies or TV shows but shouldn't be an issue for most usage. Other than this, the central area of the screen is very uniform which is great as it results in very little dirty screen effect when browsing web pages or watching sports clips.

The 5% gray uniformity is even better, producing a low standard deviation and DSE which is excellent.

The black uniformity is poor. Looking at our test picture, we can see that backlight bleed is visible near the bottom and top edges. This does result in a worse dark scene performance as blacks appear blotchy. There are also some faint horizontal lines, but those lines are not visible while watching normal content, so they are not really problematic.

Out of the box, the Dell U2717D monitor has a decent accuracy. The picture mode with the best accuracy was the 'Custom Color', and this with the default red, green, and blue values (100-100-100). The next more accurate picture modes were the 'Standard' and the 'sRGB' picture mode, which both had a similar white balance dE (5.39 and 5.6) and color dE (3.76 and 3.42).

Looking more in detail the result from the 'Custom Color' picture mode, the white balance dE is a bit high, enough that most enthusiasts would notice the inaccuracies. For the color dE, 2.75, it is in the same ballpark as the white balance. For the color temperature, all picture mode did have a color temperature higher than our desired target of 6500k, which can be a bit too cold for some peoples.

Finally, the gamma was not far from our 2.2 target, but looking at the gamma curve, we see that it overshot the target curve in the dark IRE and did dip in the brighter end.

After calibration, which was also done on the 'Custom Color' picture mode, the Dell U2717D has an excellent accuracy. Both the white balance dE and color dE were brought down by almost half, and are now hovering just above the level which most people would not notice any inaccuracies.

The color temperature after calibration is warmer, but a bit more than our 6500k color temperature, but it is within an acceptable range.

As for the gamma, it is much more on target, especially the curve, which is tracking the target curve much more closely.

Excellent SDR color gamut. The monitor can reproduce the standard RGB (s.RGB) color space almost perfectly. Unfortunately, it does not offer proper Adobe RGB color space tracking, so its performance in the more demanding color gamut is a bit lackluster.

Good SDR color volume. The Dell U2717D has no issue covering the great majority of the s.RGB color volume, with most of its limitation being caused by its lower contrast ratio which stops it from displaying darker tones. Unfortunately, as was seen in our color gamut test, the Adobe RGB coverage is less than desirable.

The Dell U2717D has a great performance while displaying our gradient test image. The 8-bit banding is visible and this is due to the limitation of this monitor, but besides that, only small color issues are visible in the darker shade of color, which does not really results in any problems while looking at normal content.

Very good response time, which is great for watching fast moving content such as playing fast-paced video games or watching sports. Almost all the blur in the photo is due to persistence; only a faint ghosting trail can be seen following the moving logo, and no smearing is visible. The 'Response Time Normal' setting was the most balanced; the 'Fast' setting introduced a lot of bothersome overshoot and so is not recommended.

The Dell U2717D has a flicker-free backlight at all brightness levels, which is great and produces smooth motion when browsing the web. Unfortunately, the monitor doesn't have an optional black frame insertion feature that intentionally adds flicker to clear up motion, but lack of BFI is common for 60 Hz monitors because most people find 60 Hz flicker bothersome.

The native resolution input lag is oddly high, far higher than most monitors. During most usages this high input lag can only be felt if the user is sensitive to input lag, but for gaming it will impact performance in many scenarios. The high input lag was also very inconsistent: when the monitor is allowed to sleep then woken up the lag is ~33ms, when it's powered off for a while then powered back on the lag is ~40 ms, and when it's unplugged or factory reset the lag becomes ~26 ms. Even stranger, non-native resolutions like 1080p somehow avoid this issue and have low input lag. This high input lag wasn't seen on the 2015 Ultrasharp U2715H, so Dell may have added extra processing to this 2017 model that increased the input lag to what it is now.

The monitor has a DisplayPort Out for daisy chaining with another monitor; this allows two monitors to be fed from one DisplayPort on a computer. Also, the lower of the two USB ports on the side supports the USB BC1.2 battery charging standard and has a different icon. This gives it enhanced charging capabilities, such as higher current modes.

This monitor has a DisplayPort Out that supports Multi Stream Transport (MST), which can be used for daisy chaining with another display. This allows a computer to feed the monitor the video feed for two monitors, and the U2717D fowards the second feed to the second monitor, effectively allowing dual monitors using only one port.

Also there is an option to leave the USB ports on while the monitor is on standby, so it can still act as a USB hub.

The monitor has a standard four button control scheme for the OSD, and one power button. The buttons have decent tactile feedback and don't take up much bezel space because the bottom bezel is at an extreme angle, but a joystick would be better for navigating the OSD, like on many LG and Samsung monitors.
