As the most professional notebook product type, mobile workstations usually has a professional, top-level hardware configuration, such as the use of NVIDIA Quadro or AMD FirePro professional graphics cards, as well as senior management with Intel vPro features CPU, these are mobile workstations features, of course, they also have a cheap price. Perhaps in order to meet its position, Dell PRECISION M4800 uses has a “tyrant” as a symbol of the Tyrant gold, and instantly feel a kind of tall.
To ensure the safety of the body, most of Dell PRECISION M4800 are magnesium alloy body wrap, you can give the screen, powerful internal hardware protection.
In addition to the front side of the body, Dell PRECISION M4800 remaining three sides are covered with various types of interfaces, the type and quantity to describe even with a very rich and never too much. Video output included VGA, HDMI, DP three interfaces, you can achieve multi-screen display; USB interface has four, one of which support the shutdown, hibernate charging function; reader aspect Jiuhe Yi +54 mm ExpressCard inserted media card reader groove combinations, it’s compatible with almost all types of storage media cards;
Dell PRECISION M4800 mobile workstation products belong to, but it has “atmosphere” of the body, the thickness of the aspects of the same size Alienware gaming notebook is similar, regardless of size or weight is not suitable for “move”, especially in the last four kilograms travel weight, women users away, even men do not fit with its traveling.
Before discussing the screen, we take a look at the front side panel of the body of this silver rectangular design, it is easy to guess, it’s opened a switch Dell PRECISION M4800 screen, finger and push it into the body, and put on the screen you can open a screen. You can see the switch on each side of two square-shaped structure, designed with embedded beneath the occlusal form a closure system.
With the further popularization of 4K displays, some ultra-high, quasi-4K, 4K resolution notebook products has been introduced. But many people are skeptical for ultra-high resolution, and some even completely rejected this ultra-high-definition screen, that it is purely a speculation, will drag on hardware performance. In my opinion, the resolution gradually increase is a trend, this ultra-high resolution in certain professional fields still have a greater demand, such as mapping, medical and other professional and industry needs. However, for the average consumer user, just bring ultra-high resolution display quality improvement, at this stage does not make much sense, most applications do not reach such a high degree of compatibility, the video also can not to achieve this level of resolution.
Dell PRECISION M4800 can be equipped with Retina screen is a product, the highest resolution up to 3200 × 1800, PPI is 235, far more than the PPI under the same size 1366 × 768 resolution (100). PPI higher the pixel surface per unit area and more, can present a more crisp and clear images, which happens to be consistent with the positioning of its professional workstation products. Of course, if you are worried about the routine use of ultra-high resolution will reduce the icons, text size, affect your normal use, then I can say that you are worried about is entirely superfluous, Windows system to modify the default text, icons resolution setting, you can the adjustment to the appropriate size, but also guaranteed to watch movies, detail of photographs. The figure shows the ratio of the content shown in the Windows 7 system, when the user selects Windows 8 system, the maximum aspect ratio can be raised to 200%.
Top of the screen is an integrated HD video webcam photosensitive photosensitive project should be optional, not each Dell PRECISION M4800 will be standard, the author uses random with Dell Webcam Central software experience a bit, it will adjust the degree of intensity of the ambient light the brightness of the video screen, automatically fill light. Camera on the right is a white light bulb, it should be LED lights, turn on the camera when the lamp is lit. On both sides of the camera and light bulbs, as well as two holes-like structure, which is an integrated digital array microphone noise removal.
Dell PRECISION M4800 is also a screen can achieve the level of open products, a great convenience for the user, after the 180-degree turn on the screen can show content to others, although the screen at 90 degrees perpendicular to also show to others, but in show when similar engineering drawings, 180-degree horizontal sense more entities. And it’s gone through tens of thousands of times the shaft opening and closing test, user need not worry about the quality of the shaft.
Dell PRECISION M4800 came to control the region, it is equipped with a full-size keyboard input speed can be improved presentation, especially digital aspect. In the bottom right of the keyboard is its fingerprint reader, after a FIPS (Federal Information Processing Standard) certification, is its ability to protect an affirmation. And the fingerprint reader does not like this on the commercial strip to see the kind of mellow recognizer, also requires the user to slide a finger thereon to identify, Dell PRECISION M4800 uses a full-sized fingerprint reader, put your finger in the above can be, without sliding.
In my opinion, a backlit keyboard should be counted as a quasi-standard business notebook design, but more professional mobile workstation then it should be the standard, it can improve the accuracy of text input in a dark environment, but there is little that is beautiful, dark environments it is very “burn” gas. Keyboard backlight brightness level of a total of four, by Fn + → arrow keys can be achieved switch and brightness adjustment.
Dell PRECISION M4800 will power key, the wireless key (body surface), volume keys and mute key independent, because the first two are set independently relatively simple, basically most notebooks have adopted such a design, but the mute button is individually designed on very rare. In fact, this is in order to meet the needs of business users when responding to emergencies, such as when conducting a video conference, video playback or copy entertainment, suddenly received a phone customer or leadership, the user can achieve a mute button, no longer was “Fn + Fx” engage in a rush.
With the traditional two-button design is different, Dell PRECISION M4800 uses a three-button multi-touch touchpad, but to achieve the multi-touch functionality you need to install the Dell touchpad management procedures.
