Nothing about the Latitude 5420 suggests it might be a good laptop for anything unrelated to work, so perhaps it’s no surprise the display fails to hold up. The Latitude 5420's display is easily visible outdoors and under bright lights, thanks to its 923 nits of maximum brightness. To put that into context, the average premium laptop's display illuminates to just 329 nits. Viewing angles are also strong; I had no problems reading text no matter where I stood in relation to the laptop. The next figure shows how well the display can reproduce dark parts of an image, which is essential when watching movies or playing games in low ambient light. The display covers 110 percent of the sRGB color gamut, according to our colorimeter measurements. Although that's slightly below the premium laptop average (117 percent), the panel never looked dull.
From the bumpers covering each corner to its magnesium-alloy materials, this laptop's utilitarian design may as well have been contrived in a secret military lab. The fans inside the Latitude 5420 did a reasonable job of keeping this beast cool, but the underside warmed to uncomfortable temperatures. After playing a 15-minute HD video in full screen, the bottom of the laptop, near the hinge, reached 104 degrees Fahrenheit. Fortunately, that was the only location on the laptop that breached our 95-degree comfort threshold. The Latitude's touchpad peaked at just 86 degrees, while the center of the keyboard remained a bearable 94 degrees. Yes, the Latitude 5420 is more beast than beauty, but that's sort of the point. From the bumpers covering each corner to its magnesium-alloy materials, this laptop's utilitarian design may as well have been contrived in a secret military lab. Exposed screws, geometric angles and chunky bezels assure the user that no expense was spared in creating the Latitude 5420's practically indestructible chassis.Apple Silicon still has it beat, though. The MacBook Pro we recently tested handled 14 hours of our battery life, a full four and a half hours more than the Latitude 5420. The speakers sound powerful However, this doesn’t stop the Latitude 14 5420 to provide some computational performance to its users. Interestingly, the laptop is offered with both Comet Lake-U and Tiger Lake processors. Why? We don’t know. What we do know is that the 10nm architecture of Intel introduced a huge boost in performance. Not only when it comes to CPU-intensive loads, but to graphics power as well. So, getting the so-called “11-th Gen” processors would be a priority.
Turn the laptop upside down, and you will find the ventilation grills and the speaker cutouts. Unfortunately for left-handed people, the heat exhaust is placed on the left side of the notebook. Armed to the teeth with high-end components, the 5420 Rugged impressed in our performance benchmarks, scoring a 16,054 on the Geekbench 4.1 test. That strong result tops the premium laptop category average (13,113) by a large margin. Also pre-installed on the Latitude 5420 is a program for adjusting the laptop's discrete AMD graphics settings and an app called eGalaxDr.Touch, which lets you optimize the touch screen for use with gloves, a pen or in wet conditions. Connect confidently:Stay connected with up to 450 Mbps LTE mobile broadband speeds. Wi-Fi 6E allows 7 additional channels (in 6GHz band) for more bandwidth which provides faster, smoother Wi-Fi, especially in high-density areas.* Travel with ease with new eSIM technology that connects to more global carriers without having to switch SIM cards.*
And although its 512GB PCIe NVMe Class 40 SSD couldn't keep up with the category average (526.7 megabytes per second) on our File Transfer Test, it still duplicated 4.97GB of mixed-media files in a reasonably fast time of 10 seconds for a rate of 508 MBps. There are hardly any tablets in this display size range anymore. For subnotebooks, on the other hand, it is the standard format. While the 5420 Rugged is an unquestionably durable machine, it isn't quite as rugged as the more premium (and much larger) Latitude 7424 Rugged Extreme, which survived additional tests, including a drop from 6-feet high, an "explosive atmosphere" and blowing rain. The Dell Latitude 5420 is not entirely hopeless. It has a great keyboard, excellent connectivity, and good battery life.
Our “Design and Gaming” profile delivers optimal color temperature (6500K) at 140 cd/m2 luminance and sRGB gamma mode.The advantage of subnotebooks is that the entire laptop can be small and therefore easily portable. The smaller display also has the advantage of requiring less power, which further improves battery life and thus mobility. The disadvantage is that reading texts is more strenuous on the eyes. High resolutions are more likely to be found in standard laptops.» To find out how fine a display is, see our DPI List.
For that reason, the Latitude 5420 Rugged is the better option for most people, and a highly recommended laptop for the world's toughest jobs.I do have a few minor qualms with the keyboard. For one, some of the keys, especially the arrow keys, are undersized, which could be a problem for those who work with gloves on. Also, the optional handle installed on the front of the laptop doesn't make for the most comfortable wrist rest, and the RGB lighting settings are very basic. Audio quality is not where we’d expect the Latitude 5420 to excel. Work laptops often don’t prioritize audio, and this laptop makes no claims about enhanced sound.

Thời lượng Laptop Dell PIN trâu bò với 4 Cell 63Wh có thể sử dụng lên đến 5 giờ sử dụng liên tục đa tác vụ. The Latitude 5420 we tested had Intel’s Core i7-10610U quad-core processor. It’s an upgrade from the Core i3 processor found in the base configuration, but it certainly didn’t feel like it.
