You've probably seen an employee or colleague using multiple LCD monitor for the job of the computer. Research at the University of Utah shows that using multiple monitors can significantly improve employee productivity. E 'could be integrated more when the computer monitor had DVI or HDMI, but computers are equipped with this feature is still rare. Currently, less than 2 percent of the jobs have more than one monitor. There is aThe need for a simpler solution.
A new USB to HDMI adapter module has recently introduced can help. The GrandTec Grand HD Electronic Cinema "(GHD-2000) is inserted into a USB port for use as output for up to 6 monitors (4 for Mac). This is also an easy way for an HDTV adapter for a laptop to implement. This module is about the size of a power adapter for a laptop. What makes this product different from its competitors is the integrated circuit chip and softwareDriver, the "Display Link" technology.

Display Technology Link
The chips used are critical to a company called DisplayLink: fact (formerly Newnham Technology displaylink.com, website). The company is located in Palo Alto, California, with research and development operations in Cambridge, England. DisplayLink is a fabless company, so that the production of integrated circuits is probably carried out in Taiwan.
The technology, DisplayLink supports 32-bit color at allResolutions. If you can detect the native resolution, DisplayLink displays the native resolution of your screen automatically. The video output is in a position of high definition (720p) and audio functions for a single channel is also integrated. DisplayLink provides much of the software to automatically configure the video card and the USB port.
DisplayLink compresses the video signal for transmission over the USB connection to improve bandwidth. The video signals, in particularuncompressed HDTV signals, in case of huge bandwidth requirements. If the original video is encoded (see MPEG), then the first computer to decode the signal. Then, the DisplayLink driver software to compress the signal using the proprietary video codec compression DisplayLink. This is basically transcoding, which is one reason that the different needs of the computer. The compressed signal is then sent via the USB connection for the adapter.
Once the signal is overUSB-Link decompressed, the converter, the signal for transmission over the HDMI connection. HDMI is able to communicate uncompressed HDTV signals.
There are some misleading information online, which states that this product is compatible with HDCP, which means that the system is, among other things, implies BluRay DVD compatible. Currently the technology is not HDCP compatible DisplayLink, DisplayLink manipulate because compression codec packets are not encrypted.
Fast-moving images, stressAbility of this technology, since the speed limit USB 2.0.
Computer Requirements
The minimum system requirements for this application, an operating system XP or Vista with a Pentium 4 2.4 GHz or equivalent. Minimum requirement is 512 MB of RAM. The converter module is based on the computer's CPU to do video encoding. The product is plug and play with the included software, and it was easy to install.
Power is supplied to the drivethe USB port, so do not need an AC adapter.
Videowall
E 'possible to have a "video wall" with up to 6 screens to implement, but only a single audio channel can be used. Each screen can be rotated independently in increments of 90 degrees.
The system supports video desktop (a single split image with multiple monitors) (see the same image on multiple monitors) or mirror-imaging extended. A separate USB-to-HDMI adapter module is required for each monitorin extended desktop mode.
With several USB-to-HDMI adapter, each monitor shows programming. The limitation on the ability of computers to each channel, because the process is computationally expensive to encode.
Many people use their computers to watch movies on TV and watch. E 'must be able to easily view the computer to an HDTV bigger. The GrandTec Grand Electronic Cinema HD is suitable for this purpose. The Grand Cinema HD is currently selling on-linefor $ 130 - $ 150
