The Dell UltraSharp range has been one of the most popular ranges of displays for over 10 years now. Dell seem to update their models and add new options to the range every year or two and we've reached the time where they've decided to refresh most of their popular models. We have with us now the U2417HJ, the replacement to the very popular U2414H from 2013/14. This screen is 23.8" in size like its predecessor, with the H signifying it is 16:9 aspect ratio - offering a 1920 x 1080 resolution. Much of the design, spec and feature set remains quite similar to the older model, but we will make comparisons with the U2414H throughout the course of the review.
It's worth noting that there are actually 3 different versions of the new U2417H display, all slightly different in terms of features and extras, and with slightly differences with the underlying panel. All 3 versions technically replace the U2414H screen, but there are a few differences you should be aware of before making a decision. As well as this review of the HJ model, we will also shortly be reviewing the U2417H, which will cover the H and HA model performance.
The three slightly different versions of the U2417H are:
U2417HJ - This is the model sent to us first of all for testing and what this review is based on. It is the most similar in design to the old U2414H. It has the same video inputs as the U2414H, including DP, Mini DP and 2x HDMI. The main difference on the new U2417HJ is that it has a wireless charging function built in to the stand for Qi/PMA compliant devices. The stand is the same design we've seen from previous UltraSharp models including the previous U2414H from a couple of years ago. It has a light silver colour used for the stand and base, and an elongated cable tidy hole in the back. The only difference with the stand is the integrated wireless charging point and small LED charging light [see later pictures in this review].
The screens bezel dimensions and appearance are very similar to the old U2414H. The back of the screen is a matte black colour entirely like the U2414H was. There are 4 USB 3.0 ports on this model, 3 on the underside with the other connections, and one on the back [visible in the lower right area above] which also has charging capabilities, again the same as the U2414H. Even is identical and has not been updated with any new options. Dell have forgotten to update the model name in the OSD software so it still reads 'U2414H' in fact. The has been changed though compared with the old U2414H, moving from an LG.Display IPS panel to a Samsung PLS equivalent. So the main changes from the U2414H are the different underlying panel, and the charging function built in to the stand.
U2417H - the "normal" U2417H is more different to the old U2414H. It has a four-side zero-bezel design, minimising the size of the lower bezel from the U2414H and U2417HJ models. It has a two colour toned back as shown in the pictures here [silver and black]. The front of the stand and the base is also a darker silver colour like we had seen on the Dell S2716DG recently, with a circular cable tidy hole in the back as shown above. There are 2x USB 3.0 ports located on the left hand edge of the screen at the bottom too [not on the HJ] for easy access, although there are still only 4 in total.
This H model is missing one HDMI connection and the wireless charging function compared with the HJ. It does have an updated OSD software though, including an additional response time setting in the OSD menu. The HJ model doesn't have a response time setting in the OSD menu although we've seen in the past that actually the 'normal' setting tends to be optimal anyway on models with an additional 'fast' option, so this extra setting probably isn't even missed on the HJ model. The underlying panel is slightly different to the HJ model. Again Dell have moved away from an LG.Display IPS panel from the U2414H and to a Samsung PLS equivalent. It is a different revision in the H model [LTM238HL04] compared with the HJ [LTM238HL01]. We will review the H model separately and make comparisons of the performance between that and the U2414H / U2417HJ displays.
U2417HA - this model is basically the same as the U2417H, with the same underlying panel, four side zero-frame design, two coloured back, 2x USB ports on the left hand edge, additional response time setting in the OSD menu and one less HDMI connection than the U2417HJ model. The difference between this and the normal U2417H is that rather than a monitor stand, it is provided with a mounting arm as shown in the above pictures.

The U2417HJ offers a very good range of connectivity options with DisplayPort, Mini DisplayPort and 2x HDMI [MHL supported] connections offered. There is also a DisplayPort output for Daisy Chaining support. The digital interfaces are HDCP certified for encrypted content and the video cables are provided in the box for DisplayPort > Mini DP only. It's worth noting that the normal U2417H and U2417HA models offer the same video connections, minus one of the HDMI inputs.
The screen has an internal power supply and comes packaged with the power cable you need. There are also 3x USB 3.0 ports located on the underside of the screen with the video connections and 1x port on the back of the screen, which also has charging capabilities. On the normal U2417H and U2417HA models there are 2x USB ports on the underside, and 2x on the left hand edge of the screen instead.

The U2417HJ is part of Dell's 'zero frame' designed UltraSharp range. There is a thin bezel around all the edges giving it a sleek and sharp design, ideal also for multi-screen set ups. Around the sides and top of the screen is a very thin 1.5mm plastic edge, and then a 4mm inner panel border before the image starts [total of 5.5mm black edges around the sides and top]. Along the bottom edge of the screen is a matte black bezel measuring ~15mm. There is a shiny silver Dell logo in the middle of this bottom bezel, and in the right hand corner are the touch sensitive OSD control buttons and power button. It should be noted that the design is very similar to the U2414H which was also a zero-frame screen. The U2417H and U2417HA models move to an even smaller four-side zero-frame design as well, minimising the lower bezel as well.

The stand and base are finished in a light silver colour as shown, while the back of the screen is a matte black plastic enclosure. There is a cable tidy hole in the back of the stand as you can see from the above images. Front and back, it looks pretty much identical to the old U2414H incidentally.
The HJ model features an integrated wireless charging point in the base as indicated above and talked about in more detail in the introduction section of this review. We liked this as a feature and no doubt this will become increasingly useful in the coming years as more and more phones switch to this technology. A cool new feature we would like to see more often.
Above: full tilt range shown. Click for larger versions
The screen offers a full range of ergonomic adjustments. Tilt is smooth to move but a little stiff. It offers a good adjustment range as shown above.
Above: full height adjustment range shown. Click for larger versions
Height adjustment is also available with smooth movement which is a little easier to re-position than tilt. At the lowest setting the bottom edge of the screen is ~95mm from the top of the desk, and at maximum extension it is ~180mm. This gives a total adjustment range of ~85mm which is fairly modest but adequate.
Side to side swivel is smooth but fairly stiff, sometimes resulting in the whole screen and base moving instead of just the screen shifting side to side and the base remaining stationary. Rotation is also offered but is stiff to use, although at least fairly useable on a screen this size. Overall the screen remained stable on the desk with no wobbling.
A summary of the screens ergonomic adjustments is shown below:

The materials were of a good standard and the build quality felt good as well. There was no audible noise from the screen, even when conducting specific tests which can often identify buzzing issues. The whole screen remained cool even during prolonged use as well which was pleasing.
Above: interface connections. Click for larger version
The back of the screen features the interface connections as shown above. There are [from left to right] the power connection, DisplayPort in, Mini DisplayPort, DisplayPort out, 2x HDMI [MHL], audio out, USB upstream and 3x USB downstream. To the right you can also see the additional USB port [with charging capabilities] in the back of the screen for easier access. It's not as easy as when they are located on the side of the screen like they are on the U2417H and U2417HA models, but still a bit easier to get to than those underneath. The lack of DVI or VGA connections may be limiting for some older systems, but most modern devices and graphics cards should be offering HDMI or DisplayPort nowadays.
Above: OSD control buttons on the bottom right hand corner. Click for larger version
The OSD menu is controlled from a series of 4 touch-sensitive buttons on the lower right hand edge of the front bezel. There are 4 small grey circles on the front bezel to mark where the controls are. There is also a touch-sensitive power button which has a small rectangular LED beneath it which glows white during operation and pulsates on and off [white] during standby.
Pressing any of the four buttons pops up a quick access menu as shown above. There are quick access options to get to the preset modes and the brightness/contrast controls by default. Note that we've actually changed the preset quick launch in the photo above to instead offer access to the input selection. These can be customised within the main OSD menu if you would prefer quick access to other settings as well.
As an example of what the quick launch option looks like when selected, the brightness and contrast quick access menu is shown above.
The main OSD menu is split into 8 sections down the left hand side as shown above. We spotted an error on Dell's part here, as the model name says U2414H here at the top left, even though it is the updated U2417HJ model! On the U2417HJ at least, they've used the exact same OSD software and forgotten to update the model name at the top. We have confirmed that Dell will have updated the software properly on the U2417H / HA versions though. Anyway, because of this error we can shamelessly use the images from the previous U2414H review as nothing has changed!
In the top right hand corner is Dell's "energy use" bar which gives you an idea of your power consumption. You can scroll down the left hand menu sections and the options available within each section are then shown on the right.
The input source section allows you to switch between the video inputs as shown above.
The 'color settings' section allows you to access the preset modes and make a few other alterations relating to colour control. The preset mode options are shown above as well for reference.
The 'Display settings' section allows you to control a few advanced features. There is access to the hardware aspect ratio control settings [16:9, 4:3 and 5:4 modes available] and the as well, if you're in a suitable preset where it is available.
The other sections shown above are pretty self explanatory. All in all the menu was fast and easy to use. Navigation felt simple and intuitive and the touch-sensitive controls worked well. No complaints here.
In terms of power consumption the manufacturer lists typical usage of 16.0W and 3, the color displayed is significantly different from the theoretical one, meaning that the difference will be perceptible to the viewer. If DeltaE 100,1000 Euro, requiring extremely high bandwidths and very complicated methods to trigger the correct behaviour and accurately measure the signal processing on its own. Other techniques which are being used since are not conducted by Thomas [he is a freelance writer] or based on this equipment or technique, and may also be subject to other errors or inaccuracies based on our conversations with him since. It's very hard as a result to produce a technique which will measure just the signal processing on its own unfortunately. Many measurement techniques are also not explained and so it is important to try and get a picture from various sources if possible to make an informed judgement about a display overall.
For our tests we will continue to use the SMTT tool to measure the overall "display lag". From there we can use our oscilloscope system to measure the response time across a wide range of grey to grey [G2G] transitions as recorded in our . Since SMTT will not include the full response time within its measurements, after speaking with Thomas further about the situation we will subtract half of the average G2G response time from the total display lag. This should allow us to give a good estimation of how much of the overall lag is attributable to the signal processing element on its own.
Lag Classification
To help in this section we will also introduce a broader classification system for these results to help categorise each screen as one of the following levels:
- Class 1] Less than 16ms / 1 frame lag - should be fine for gamers, even at high levels
- Class 2] A lag of 16 - 32ms / One to two frames - moderate lag but should be fine for many gamers. Caution advised for serious gaming and FPS
- Class 3] A lag of more than 32ms / more than 2 frames - Some noticeable lag in daily usage, not suitable for high end gaming

Class 1
We have provided a comparison above against other models we have tested to give an indication between screens. The screens tested are split into two measurements which are based on our overall display lag tests [using SMTT] and half the average G2G response time, as measured by the oscilloscope. The response time is split from the overall display lag and shown on the graph as the green bar. From there, the signal processing [red bar] can be provided as a good estimation.
The screen showed a total average display lag of only 5.00 ms as measured with SMTT 2. Taking into account half the average G2G response time at 4.35ms, we can estimate that there is ~0.65 ms of signal processing lag on this screen. Basically nothing at all. This puts it on par with the old U2414H model as well which is great news and means the screen should be fine for gamers.
The following summarises the screens performance in video applications:
- 23.8" screen size makes it a reasonable option for an all-in-one multimedia screen, but being quite a bit smaller than most modern LCD TV's of course.
- 16:9 aspect ratio is more well suited to videos than a 16:10 format screen, leaving smaller borders on DVD's and wide screen content at the top and bottom.
- 1920 x 1080 resolution can support full 1080 HD resolution content
- Digital interfaces support HDCP for any encrypted and protected content
- Good range of connectivity options provided with DisplayPort, Mini DisplayPort and 2x HDMI [with MHL] offered.
- Cables provided in the box for DisplayPort to Mini DP only.
- Light AG coating a positive change providing clean and clear images, without the unwanted reflections of a glossy solution.
- Wide brightness range adjustment possible from the display, including a maximum luminance of ~240 cd/m2 and a decent minimum luminance of 30 cd/m2. This should afford you good control for different lighting conditions. Contrast ratio remains stable across that adjustment range as well and is excellent for an IPS-type panel. Brightness regulation is controlled without the need for PWM and so is flicker free for all brightness settings.
- Black depth and contrast ratio are strong for an IPS-type panel at 1228:1 after calibration. Detail in darker scenes should not be lost as a result.
- There is a specific 'movie' preset mode available for movies or video if you want but it is much cooler than our calibrated custom mode. May be useful to some though.
- Good pixel responsiveness which should still be able to handle fast moving scenes in movies without issue. No overshoot issues which is pleasing.
- Wide viewing angles thanks to IPS-type panel technology meaning several people could view the screen at once comfortable and from a whole host of different angles. They are not quite as wide as we would have liked vertically, showing more colour tone shift compared with other IPS panels we've tested.
- IPS glow is moderate meaning you might experience some annoying white glows on darker content from an angle. It is not a low-glow panel like the U2414H before it.
- Very good and mostly easy to use range of ergonomic adjustments available from the stand, so should be easy to obtain a comfortable position for multiple users or if you want to sit further away from the screen for movie viewing.
- No particularly noticeable backlight leakage, and none from the edges which is good. This type of leakage may prove an issue when watching movies where black borders are present but it is not a problem here.
- No integrated stereo speakers on this model but it is compatible with Dell's SoundBar if you want. There is also an audio output connection.
- Moderate range of hardware aspect ratio options with 16:9, 5:4 and 4:3 modes available which should be fine for most uses.
- Picture in picture [PiP] and Picture By Picture [PbP] are not available.
Dell have produced another excellent all round screen here, and one that does the well-established UltraSharp brand proud. The design remains basically identical to the old model but is sleek and attractive, and also very practical for multi-screen setups should you want. As ever, Dell have provided a decent stand and a wide range of connectivity options for what is still a very reasonably priced display. We really liked the addition of the wireless charging function on this HJ model and we hope to see that become more popular as the technology is integrated in to more devices in the future.
The default setup and factory calibration of the screen was strong and we were very impressed with the high contrast ratio from this IPS-type panel. The light AG coating and flicker-free backlight were as welcome as ever of course. Response times were as good as you can hope for from a 60Hz IPS-type panel and lag was non-existent too. We were a little disappointed with the viewing angles of this Samsung panel, being a little more restrictive vertically than we are used to. Also the U2414H had been a nice low-glow panel which has been dropped here which is a shame. It was never part of their spec or anything, but it's a shame they couldn't continue to use a low-glow panel option here.
If we compare it to the old U2414H there isn't a huge amount that's changed. The design, stand and connectivity options are basically identical. On this HJ model they have at least added the wireless charging function which is welcome. Underneath all that the panel characteristics are very comparable in many places, and both offer excellent all round performance. The pixel response times and lag are basically the same, flicker free backlights are used on both and of course things like the resolution remain unchanged. There is a little difference between the two though. We felt the U2417HJ had the edge in terms of the out-of-the-box setup, with a more accurate factory calibration and certainly a decent contrast ratio improvement. On the flip side, the viewing angles were a little more restrictive, it didn't use a low-glow panel like its predecessor and the uniformity wasn't as good [on our sample]. There's not really much to separate the two unless you specifically want the wireless charging function, or if the U2414H is no longer available to buy.
In terms of the 3 versions of this U2417H, again that really just comes down to whether you want the wireless charging function and additional HDMI port that the HJ model offers. Regardless, all 3 should offer very good all round performance and would be excellent choices in the 24" space we expect. Our U2417H review should be published soon as well to compare if you are more interested in the H / HA models.
