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. Like most 14-inchers, the Latitude 14 7480 offers only an M.2 SSD slot (located right next to the battery) – no 2.5-inch drive bay, unfortunately. Anyway, SSDs with the 2280 standard fit in while the motherboard itself supports PCIe NVMe SSDs. However, our unit shipped with SanDisk X400 M.2 running on SATA III controller, which is a big let-down since the laptop falls into the premium segment. Our Latitude 7480 is equipped with a 4-cell Express Charge Capable battery with a healthy capacity of 60 Wh - good enough for a solid WLAN run time of 12 hours. While the Latitude 5480 with its even higher-capacity battery (68 Wh) lasts about 4 hours longer, the result is still quite impressive - especially when considering that the predecessor with QHD display and a 55 Wh battery didn't even last half as long. The maximum and minimum run time are also surprisingly good for this category. For most usage scenarios, the notebook will easily last the entire workday. The “Design and Gaming” profile is created at 140 cd/m2 brightness, D65 (6500K) white point and optimal gamma in sRGB mode. It appears that the display doesn’t use PWM across all brightness levels making it safe to use for long periods of time in this regard.
The TDP depends on the CPU model but it’s usually equipped with a SoC rated at 15W including the memory controller.The average temperature for the upper side under maximal load is 29.5 °C / 85 F, compared to the average of 29.5 °C / 85 F for the devices in the class Office. The palmrests and touchpad are cooler than skin temperature with a maximum of 24.2 °C / 75.6 F and are therefore cool to the touch. This section provides links to articles about diagnostics and the various error messages, beep codes and Diagnostic LED codes that can help to troubleshoot potential hardware and software issues on your system. At first, we weren’t expecting any mind-blowing results but after the tests, the battery life on this thing is just phenomenal. Thanks to the big 60Wh battery and the energy-efficient ULV (ultra-low voltage) Intel Core i5-7200U CPU, the laptop reaches the second position in our battery ranking table with just a few minutes shy to our current leader – the HP Spectre x360 13. All tests were performed with the usual settings – Wi-Fi constantly running, screen brightness set to 120 cd/m2 and Windows battery saving feature turned on. Web browsing
In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 82% of all devices are better. 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. This means that the measured response time is worse than the average of all tested devices (21.8 ms). SupportAssist, previously called My Dell, provides system updates, detects issues and sends you alerts based on your device, which makes solving and preventing problems easier than ever. This application gives you access to everything you need to take the guesswork out of maintaining PCs and tablets. For more information and installation instructions see the following link:The maximum dE2000 color deviation is 2.7, which isn’t bad since values above 4.0 are usually unwanted especially when there’s color sensitive work involved. The contrast ratio is good – 1010:1. LG Philips LGD0557 tested with X-Rite i1Pro 2Maximum: 344.4cd/m² (Nits) Average: 321.2cd/m² Minimum: 16.08cd/m² The maximum temperature on the upper side is 39 °C / 102 F, compared to the average of 34.2 °C / 94 F, ranging from 21.2 to 62.5 °C for the class Office.
The Latitude 7480 is a high-quality and solid business laptop. Its ever-present coil whine could be a deal breaker for some, however. Excellent review. Thank you. Would like to put a question, which constitutes for me, by now, an issue: what about the keys “Home” and “End” being not dedicated ones, but force us to press 2 keys (Fn+Home) to obtain the same job as in the most keyboards? In comparison, all tested devices range from 0.2 (minimum) to 636 (maximum) ms. » 58% of all devices are better. This profile is aimed at designers who work with colors professionally, and for games and movies as well. Design and Gaming takes display panels to their limits, making them as accurate as possible in the sRGB IEC61966-2-1 standard for Web and HDTV, at white point D65. While not nearly as glamorous as Dell's own 13-inch and 15-inch XPS siblings, the Latitude 7480 is in some way the business-equivalent of those well-received mainstream machines. The good-looking 14-inch laptop is smaller and much lighter than before, but the build quality remains unquestionably high. The chassis is rigid with tight tolerances and features a soft, touch-friendly finish. The display is bright with accurate colors and non-glare as well, so road warriors won't have to deal with annoying reflections. The performance is top-notch - even though the CPU specific tests fall slightly short, the notebook excels when it comes to synthetic benchmarks - and the battery lasts all day even if it shouldn't be complete charged. The input devices are also very good with the keyboard in particular getting our nod as one of the best ones available on the market today.In idle usage, the average temperature for the upper side is 24.5 °C / 76 F, compared to the device average of 29.5 °C / 85 F. Office Work should be used mostly by users who spend most of the time looking at pieces of text, tables or just surfing. This profile aims to deliver better distinctness and clarity by keeping a flat gamma curve (2.20), native color temperature and perceptually accurate colors. CAUTION: Before working on your machine it is worth considering the following safety information: Safety precautions when working with electrical equipment
