Dell describes the Latitude 14 7440 as "designed to impress". That's a bald claim but at least on specs, the device looks like a compact 14-incher that can be full of features. The amount of goodies under the hood depends on how wide your wallet is because the fingerprint reader, the IR Web camera, the NFC sensor, the LTE / 5G connectivity, and the Smart-card reader are optional. In addition to that, you can opt for a vPro CPU and Intel Evo certification. You choose between a plethora of Raptor Lake CPU options including 15W U-series chips and 28W P models. You also get a fancy Mini LED backlit keyboard that should be more battery-friendly compared to conventional backlight (at least on paper). All notebooks have a dTPM 2.0 chip for enhanced data encryption which is very important for an office machine like this one. The display has a 16:10 aspect ratio - the screen is taller compared to a normal 16:9 panel which is useful for working with spreadsheets or Web browsing. Three 1200p units are available and for those who prefer crisper image quality, there is an optional 1600p variant. The device also boasts Wi-Fi 6E, four speakers, and a modern port selection.

Inside the package, you will find some paperwork and the laptop itself. Depending on the CPU, you get a 60W, 65W, or 100W Type-C adapter. Design and construction The Dell Latitude 14 7440 looks like a typical up-to-date office machine. It has a clean design with minimal branding. Our device is made of aluminum and there is a slightly different (and lighter) magnesium version (branded as "laptop-ultralight"). The lid can be flexed a bit and we saw slight bends in the zone between the Space key and the touchpad. Also, the center of the keyboard deck can be pressed down a bit during harsh typing. The lid can be opened smoothly with a single hand. The starting weight of the laptop is 1.33 kilos - yep, this one is definitely light. The profile thickness is 17.10 - 18.19 mm. The bezels around the panel are narrow. Above the display, you get a Full HD 30 FPS Web camera with a privacy shutter and Temporal Noise Reduction. Two optional IR MIPI units are available - one 1080p and one 5MP model. They support ExpressSign-in - the sensor detects your presence and will wake the system when you are in front of the laptop. The device will be automatically locked when you are away from it. The device can lay fully flat on your desk. The lid has a lever design so it'll lift the back of the base when the angle of opening is wider than 90 degrees. This provides more fresh air to the cooling solution. Two speakers surround the Mini-LED backlit keyboard. It's comfortable for work thanks to the long key travel and the clicky feedback. During typing, the keycaps produce a bit more noise than usual. The power button doubles as a fingerprint reader (option). No complaints regarding the touchpad - it's wide, smooth, and accurate. Two long rubber feet, two speaker cutouts, and a ventilation grill are placed on the bottom plate. The hot air is being exhausted through a vent on the back of the device that aims directly at the lower bezel of the display. Some amount of heat makes its way to the panel during heavy CPU loads. Ports On the left, we can see an HDMI 2.0 connector, and two Thunderbolt 4 / USB4 ports (with power delivery and DisplayPort 1.4 capabilities). On the right, we can spot a lock slot, two USB Type-A 3.2 (Gen. 1) ports (the former supports the PowerShare function), and an Audio combo jack. Display quality, Health impact (PWM), Sound Dell Latitude 14 7440 is equipped with a WUXGA IPS panel, model number LG Display TDVNC-140WU2 (LGD06F9; LP140WU2-SPM1). It comes with a 60Hz refresh rate. Its diagonal is 14" (35.6 cm), and the resolution - 1920 x 1200p. Additionally, the screen ratio is 16:10, the pixel density – 162 ppi, and their pitch – 0.16 x 0.16 mm. The screen can be considered Retina when viewed from at least 53 cm (from this distance, the average human eye can’t see the individual pixels). Viewing angles are good. We offer images at different angles to evaluate the quality. Also, a video with locked focus and exposure. The maximum measured brightness is 267 nits (cd/m2) in the middle of the screen and 254 nits (cd/m2) average across the surface with a maximum deviation of 10%. The Correlated Color Temperature on a white screen and at maximum brightness is 6220К. In the illustration below you can see how the display performs from a uniformity perspective. The illustration below shows how matters are for operational brightness levels (approximately 140 nits) – in this particular case at 55% Brightness (White level = 144 cd/m2, Black level = 0.11 cd/m2). Values of dE2000 over 4.0 should not occur, and this parameter is one of the first you should check if you intend to use the laptop for color-sensitive work (a maximum tolerance of 2.0). We measured a good contrast ratio - 1270:1. To make sure we are on the same page, we would like to give you a little introduction to the sRGB color gamut and the Adobe RGB. To start, there’s the CIE 1976 Uniform Chromaticity Diagram that represents the visible specter of colors by the human eye, giving you a better perception of the color gamut coverage and the color accuracy. Inside the black triangle, you will see the standard color gamut (sRGB) that is being used by millions of people on HDTV and on the web. As for the Adobe RGB, this is used in professional cameras, monitors, etc for printing. Basically, colors inside the black triangle are used by everyone and this is the essential part of the color quality and color accuracy of a mainstream notebook. Still, we’ve included other color spaces like the famous DCI-P3 standard used by movie studios, as well as the digital UHD Rec.2020 standard. Rec.2020, however, is still a thing of the future and it’s difficult for today’s displays to cover that well. We’ve also included the so-called Michael Pointer gamut, or Pointer’s gamut, which represents the colors that naturally occur around us every day. The yellow dotted line shows Dell Latitude 14 7440's color gamut coverage. Its display covers 52% of the sRGB/ITU-R BT.709 (web/HDTV standard) in CIE1976, and 40% of DCI-P3. We tested the accuracy of the display with 24 commonly used colors like light and dark human skin, blue sky, green grass, orange, etc. Below you can compare the scores of the Dell Latitude 14 7440 with the default settings sRGB. The next figure shows how well the display is able to reproduce really dark parts of an image, which is essential when watching movies or playing games in low ambient light. The left side of the image represents the display with stock settings, while the right one is with the “Gaming and Web Design” profile activated. On the horizontal axis, you will find the grayscale, and on the vertical axis – the luminance of the display. On the two graphs below you can easily check for yourself how your display handles the darkest nuances but keep in mind that this also depends on the settings of your current display, the calibration, the viewing angle, and the surrounding light conditions. Response time (Gaming capabilities) We test the reaction time of the pixels with the usual “black-to-white” and “white-to-black” method from 10% to 90% and vice versa. We recorded Fall Time + Rise Time = 26.7 ms. After that, we test the reaction time of the pixels with the usual “Gray-to-Gray” method from 50% White to 80% White and vice versa between 10% and 90% of the amplitude. Health Impact: PWM (Screen flickering) Pulse-width modulation (PWM) is an easy way to control monitor brightness. When you lower the brightness, the light intensity of the display is not lowered, but instead turned off and on by the electronics with a frequency indistinguishable to the human eye. In these light impulses, the light/no-light time ratio varies, while brightness remains unchanged, which is harmful to your eyes. You can read more about that in our dedicated article on PWM. Dell Latitude 14 7440's display doesn't use PWM for brightness adjustment. Health Impact: Blue light emissions Installing our Health-Guard profile not only eliminates PWM but also reduces the harmful Blue Light emissions while keeping the colors of the screen perceptually accurate. If you’re not familiar with the Blue light, the TL;DR version is – emissions that negatively affect your eyes, skin, and your whole body. You can find more information about that in our dedicated article on Blue Light. Health Impact: Gloss-level measurement Glossy-coated displays are sometimes inconvenient in high ambient light conditions. We show the level of reflection on the screen for the respective laptop when the display is turned off and the measurement angle is 60° (in this case, the result is 50.7 GU). Sound Dell Latitude 14 7440's speakers produce a sound of relatively good quality. However, the low, mid, and high tones all have some slight deviations from clarity.

This is a respectable result for a light 14-incher. Still, in medium loads, the chip temperature hits 94°C but at least it settles at 76°C in the long run. Comfort during full load In "Ultra Performance" mode, the fan is audible but not noisy (when the CPU is under heavy stress). For normal usage, the "Quiet" preset is the sweet spot because the fan is almost nearly silent in this mode. During max processor load, the left and the central side of the keyboard don't feel too hot to the touch. This means you can use the laptop for work even when the internals are working hard. Battery Now, we conduct the battery tests with the Windows Better performance setting turned on, screen brightness adjusted to 120 nits and all other programs turned off except for the one we are testing the notebook with. The 57Wh battery lasts for 14 hours and 17 minutes of Web browsing, or 11 hours and 7 minutes of video playback. That's a respectable result considering the modest capacity. To achieve that, you have to apply the “Balanced” preset in the Windows “Power & Battery” menu and select the "Optimized" power plan in the BIOS. Disassembly, Upgrade options, and Maintenance To open this device, you have to undo 8 captive Phillips-head screws. Next, lift the bottom panel in one of the hinge zones to create a small gap between the base and the plate. Then, you can start the prying process from there with a thin plastic tool. The safest way is to pry the sides first, then the front and the backside should be last. Here's how the bottom plate looks on the inside. This machine has the optional 57Wh battery, the default version is a 38Wh variant. To remove it, detach the connector from the motherboard, and undo the 4 Phillips-head screws that secure the model to the chassis. The optional unit lasts for 14 hours and 17 minutes of Web browsing, or 11 hours and 7 minutes of video playback. Sadly, the memory is soldered. On the bright side, the maximum possible capacity is 32GB of LPDDR5-4800MHz in dual-channel mode which sounds future-proof. At least we can have a sneak peek at the memory chips. For storage, there is just one M.2 slot compatible with 2230 Gen 4 SSDs. The preinstalled NVMe is protected by a metal shroud that has a thin thermal pad on the inside. The section on the left of the cooling is dedicated to the optional WWAN slot for LTE or 5G connectivity. Our laptop lacks this feature. The cooling is simple but it seems enough for an iGPU-only device. It has one large fan, a top-mounted heat sink, a thick heat pipe, and a heat spreader. Storage performance Our laptop has a 512GB Samsung PM9B1. Below you can see some benchmarks of this Gen 4 SSD. It reached 66°C during the benchmarking. Verdict The Dell Latitude 14 7440 is a small laptop that performs well. The cooling solution has just one big fan and a single heat pipe, but that's enough for a 2.63 GHz P core clock under heavy CPU usage. This is a very good result for a light 14-incher. Moreover, the fan isn't noisy and the keyboard doesn't feel too hot to the touch when the processor is tortured with Prime95. The 14" 16:10 1200p display has a ridiculously long name - LG Display TDVNC-140WU2 (LGD06F9; LP140WU2-SPM1). Aside from that, it's PWM-free and the viewing angles are good. Still, the sRGB coverage and the color accuracy are nothing to write home about which is normal for an office device that isn't meant for professional color-sensitive work. The battery life impresses us - more than 14 hours of Web browsing on a single charge. Our machine has the optional 57Wh model, if you pick a notebook with the default 38Wh unit and a 28W P-series CPU, maybe the autonomous life will be shorter. Just like many other compact laptops, the memory is soldered. You get up to 32GB of LPDDR5 RAM in dual-channel mode which should be enough for most users. Sadly, there is just one M.2 slot for shorter 2230 Gen 4 SSDs. The input devices are comfortable but the center of the keyboard flexes a bit during fast and harsh typing. The I/O is good for this kind of form factor - two Thunderbolt 4s plus two USB Type-A 3.2 (Gen. 1) connectors. The Dell Latitude 14 7440 is a light office device with a PWM-free display, modern I/O, and a capable cooling system.
