Strictly speaking, the company’s GXM appliance works with both laptops and desktops, though it is of greater benefit to laptop users. One downside is that using the GXM does mean that additional displays are effectively stuck in a landscape configuration and cannot be switched into portrait mode.

Beyond getting the graphics driver to work properly with the GXM, there is no need to modify the operating system or employ any form of low-level hacks. The advantage of this technique for using multiple displays is that it taps into the inherent graphics processing power of the graphics processing unit (GPU), which means that the visual experience ends up being the most seamless of the multiple display options. Depending on whether the DualHead2Go DisplayPort or TripleHead2Go DisplayPort adapter is deployed, the USB-powered GXM will split up this high-resolution output and deliver it to either two or three side-by-side monitors that are connected to its own video output ports. The technology works by means of a small GXM appliance connected to the laptop’s display output, where it masquerades as a monitor with an extraordinarily high resolution. If you don’t need portability but use a laptop at your workstation you’ll appreciate the Graphic eXpansion Module (GXM) technology developed by Matrox Graphics. Since older laptops may not deliver sufficient current from a single USB port, the ThinkVision and other models typically come equipped with a two-pronged USB cable to alleviate this problem and make it possible to use multiple displays.

Models include the Field Monitor Pro, a 4-pound portable monitor that packs a larger 15.4-inch screen and folks shut like a laptop for stowing away, and the Lenovo ThinkVision LT1421 USB monitor, which tips the scales at just 1.91 pounds (0.87kg) and draws its power entirely from the USB port. Moreover, the availability of faster CPUs on laptops and the high bandwidth available in USB 2.0 and USB 3.0 means that the usage experience no different than that of a conventional monitor for most users-and can even allow for video playback on external monitors. This is made possible by technology DisplayLink developed to compress video data and pump it over a USB link, where it is uncompressed and decoded by a specialized chip made by the company.īy embedding a DisplayLink chip into an energy-efficient LCD monitor and drawing power directly from the USB interface, manufacturers have been able to come up with portable USB monitors that can fit into the same size bag as a laptop. Professionals such as auditors and consultants who may frequently be required to work at various locations will know that a portable USB monitor used with a laptop helps to greatly increase work efficiency.
