GRANDTEC USB-to-HDMI
![Hdmi]()
You probably have a staff or colleagues with more LCD monitors to their computer workstations to see. Research at the University of Utah shows that using multiple monitors can significantly improve employee productivity. It 'was possible to integrate multiple monitors, if the computer had a DVI or HDMI, but the computers have this capability are still rare. Currently, less than 2 percent of the stations are equipped with more than one monitor. This is aNeed for a simpler solution.
A USB-to-HDMI adapter new module was introduced recently that may help. The electronic GRANDTEC "Grand HD Cinema" (GHD-2000) fits into a USB port for use as output for up to 6 monitors (4 for Mac). This is also an easy way to HDTV adapter for a laptop to implement. This module is about the size of an AC adapter to power a laptop. What makes this product different from its competitors is the integrated circuit chips and softwareDriver, the "link display" technology.
The DisplayLink technology
The chips used are critical from a company called DisplayLink (: displaylink.com formerly Newnham Technology web site) without. The company is located in Palo Alto, California, with research and product development in Cambridge, England. DisplayLink is a fabless company, so that the production of integrated circuits is probably made in Taiwan.
DisplayLink technology supports 32-bit color at allResolutions. If you can detect the native resolution, DisplayLink displays the native resolution of the screen automatically. The video output format is capable of high definition (720p) and audio functions for a single channel is also integrated. DisplayLink also has a great piece of software to automatically configure the video card and the USB port.
DisplayLink compresses the video signal for transmission over the USB connection in order to improve the bandwidth. The video signals, in particularUncompressed HDTV signals, however, require enormous bandwidth,. If the original source video is encoded (see MPEG), then the first computer to decode the signal. Then the driver DisplayLink software to compress the signal using proprietary video codec compression DisplayLink. This is basically transcoding, which is one reason that those requirements are relevant to your computer. The compressed signal is then sent via the USB connection for the adapter.
Once the signal overUSB connection, the drive signal decompression for transmission over the HDMI connection. HDMI is able to communicate uncompressed HDTV signals.
There are some misleading information online, that this product is compatible with HDCP, which means that the system involves, among other things, BluRay DVD-compliant claims. DisplayLink technology is not compatible with HDCP, as the compression codec DisplayLink can not be tampered with encrypted packets.
Fast-moving images can highlight the 'Ability of this technology, since the USB 2.0 speed limits.
Computer Requirements
The minimum system requirements for this application is an operating system XP or Vista with a Pentium 4 2.4 GHz or equivalent. Minimum requirement for RAM is 512 MB. The drive module is based on the computer's CPU to do video encoding. The product is plug and play with the included software, and is quick to install.
Power for the converter is powered bythe USB port, so an AC adapter is not required.
Videowall
And 'possible to implement a "video wall" with up to 6 screens, but only a single audio channel can be used. Each screen can be rotated independently in increments of 90 degrees.
The system supports extended desktop video (a single image split across multiple monitors) or mirroring (the same image is displayed on multiple monitors). A separate USB-to-HDMI adapter module is required for each monitorextended desktop mode.
With several USB-to-HDMI, each monitor shows a separate programming. The limitation is the computer's ability to encode each channel, because the process is computationally intensive.
Many people use their computers to watch TV and movies to see. It 'must be able to ease big is the computer signal to an HDTV. The electronic GRANDTEC Grand Cinema HD is suited for this purpose. The Grand Cinema HD is currently on sale online$ 130 - $ 150
