Welcome to a Laptop AC Adapter specialist of the Dell Ac Adapter
While most business travelers prefer to use a thin and light notebook with a small screen and a small footprint as their main travel PC, the reality is that small screens aren’t always ideal. If you need to give a sales presentation to clients in a small office space then you probably wish you had a second, larger screen to share with others while you work on your own laptop screen. HP’s solution is the EliteDisplay S140u: a USB-powered 14-inch LCD perfect for on-the-spot presentations or multi-screen multitasking.
As with most of the USB-powered mobile monitors on the market, the HP EliteDisplay S140u ($169) is a simple 14-inch LCD that weighs around 3 pounds and is less than one inch thick. Although a 14-inch monitor might sound small for a business presentation it makes perfect sense if you ever have to share PowerPoint slides with someone sitting across a desk. Also, a USB monitor makes the perfect companion if you’re used to working on a dual-screen setup at home or in your office and still want to have a second display while traveling.
One of the key design aspects that separate the EliteDisplay S140u from its competitors is the included magnetic protective travel cover that also doubles as a support stand. The case itself is black vinyl but has a faux leather exterior that gives the protective case a premium appearance.
The interior surface of the of the travel cover is soft microfiber-like material that protects the screen from accidental scratches while it’s inside your laptop bag. The case also folds over on itself to function as the stand for the LCD. It’s a simple yet functional design that gets the job done without any extra frills.
The back side of the display itself features a power button and a simple plus and minus button for controlling the screen brightness.
As with most USB monitors, the EliteDisplay S140u doesn’t feature much in terms of monitor inputs. Both the monitor’s power and video input are delivered via a single USB port on the right side of the monitor. This single input eliminates the need to carry an AC adapter with such as Dell Latitude D520 AC Adapter , Dell XPS M1530 AC Adapter , Dell Precision M65 AC Adapter , Dell Inspiron 1525 AC Adapter , Dell inspiron 1520 AC Adapter , Dell inspiron 1526 AC Adapter , Dell Latitude XT AC Adapter , Dell Studio 15 AC Adapter , Dell Latitude E4200 AC Adapter , Dell Latitude D830 AC Adapter , Dell Latitude D530 AC Adapter , Dell Latitude D630 AC Adapter or video cable but that added convenience comes with a minor inconvenience. The unfortunate side effect of using USB for the display input and power is that the 14-inch LCD panel with 1600 x 900 resolution technically requires either a single USB 3.0 port or two USB 2.0 ports in order to supply enough power.
In short, if you are connecting the EliteDisplay S140u to a USB 2.0 port, you’ll need to connect both ends of the USB “Y” cable to two USB 2.0 ports on your laptop. If you’re using a USB 3.0 port you only need to connect the cable to one USB port on your computer.
The box for the HP EliteDisplay S140u includes the monitor, magnetic cover, a USB “Y” cable, and a small package including a CD-ROM of the USB graphics drivers, the user manual printed in multiple languages, and a one-page sheet entitled, “Compatibility Issues with USB Graphics Drivers.”
That last part is the only thing you might have to worry about.
The dirty little secret of USB monitors is that there are very few companies developing graphics drivers to support displays connected via a USB port. In fact, the overwhelming majority of USB monitors on the market use DisplayLink graphics drivers. The problem is that DisplayLink graphics drivers don’t always “play nice” with every PC. The compatibility issues can be even worse if there are multiple versions of DisplayLink drivers installed on your PC (which might be the case if you happen to use a USB docking station.
For example, we connected the EliteDisplay S140u to three different PCs (Asus Transformber Book T100, Lenovo Yoga 3 Pro, and HP EliteBook 8540p) and experienced no problems whatsoever. However, when we connected the S140u to an Dell laptop which was also using a Dell USB docking station, and installed the DisplayLink Drivers from HP the driver crashed in such a way that the Dell laptop would no longer reboot into Windows and we had to use the restore partition on the hard drive to get the notebook to work again.
The bottom line is that prior to using the EliteDisplay S140u we recommend that you uninstall any DisplayLink drivers that are already installed on your PC and then download and install the latest drivers from the HP support page for the EliteDisplay S140u. Although HP doesn’t officially support Macs, Mac users “may” be able to get this USB monitor to work using the latest Mac OS 10.9 Mavericks drivers from the DisplayLink website.
