You probably have a staff or colleagues with multiple LCD screens for the computer to see their location. Research at the University of Utah shows that the use of multiple monitors can greatly improve employee productivity. And 'possible to integrate multiple monitors, if the computer had DVI or HDMI, but computers are equipped with this functionality are still rare. Currently, less than 2 percent of the workstations are equipped with more than one monitor. There is aneed for a simpler solution.
A new USB-HDMI adapter module has been introduced in recently that might help. The Grandtec Electronic "Grand HD Cinema" (GHD-2000) adapts a USB port for use as an output for up to 6 monitors (4 for Mac). This is also an easy way to implement an HDTV adapter for a laptop computer. This module is about the size of an AC adapter power supply for a laptop computer. What makes this product different than its competitors is the integrated circuit chips and software drivers, the "Display Link" technology.
Display Link Technology
The critical chips used are made by a company called DisplayLink (formerly Newnham Technology, website: displaylink.com). The company is headquartered in Palo Alto, California, with research and product development in Cambridge, England. DisplayLink is a fabless operation, so the manufacturing of the integrated circuits is probably performed in Taiwan.
DisplayLink technology supports 32-bit color at all resolutions. Whenever native resolution can be detected, DisplayLink will display the native resolution of the screen automatically. The video output format is capable of high definition (720p), and audio functions for a single channel are also integrated. DisplayLink also provides much of the software for automatically configuring the video adapter and the USB port.
DisplayLink compresses the video signal for transport over the USB link to improve bandwidth. Video signals, especially HDTV signals, when uncompressed, require enormous bandwidth. If the original signal source is encoded video (see MPEG) then the computer must first decode the signal. Then the DisplayLink software driver must compress the signal using the proprietary DisplayLink video compression codec. This is basically transcoding, which is one of the reasons that the computer requirements are significant. The compressed signal is then sent over the USB link to the adapter.
Once the signal is past the USB link, the converter uncompresses the signal for broadcast over the HDMI link. HDMI is capable of communicating uncompressed HDTV signals.
There is some misleading information on-line that claims that this product is HDCP capable, which implies that the system is amongst other things, BluRay DVD compatible. Currently DisplayLink technology is not HDCP compliant, since DisplayLink's compression codec cannot manipulate encrypted packages.
Fast moving images may stress the capability of this technology because of the throughput limitations of USB 2.0.
Computer Requirements
The minimum computer requirements for this application are an XP or Vista operating system with a Pentium 4 CPU or equivalent at 2.4GHz. Minimum RAM memory requirement is 512 MB. The converter module relies on the computer CPU to perform the video encoding. The product is Plug and play with included software, and should install quickly.
Power for the converter is supplied from the USB port, so an AC power supply is not required.
Video Wall
It is possible to implement a "video wall" with up to 6 displays, but only a single audio channel can be used. Each screen's picture can be independently rotated in increments of 90 degrees.
The system supports extended desktop video (a single image split over multiple monitors) or mirror imaging (the same image displayed on multiple monitors). A separate USB-HDMI adapter module will be required for each monitor in extended desktop mode.
With multiple USB-HDMI adapters, each monitor can show separate programming. The limitation will be the computers ability to encode each channel because of the process is computation intensive.
Many people now use their computers to watch television and movies. There is a need to be able to easily view the computer's signal on a larger HDTV. The Grandtec Electronic Grand HD Cinema is well suited for this purpose. The Grand HD Cinema currently sells on-line for 0-0.

Will share your videos or photos to your friends? Then you want to share your wonderful journey PPT or video to your friends via your laptop instead of a widescreen TV? You can use your computer to your TV? Here I will show you the way to connect a laptop or desktop on your TV.
Step 1: Connect the jack to the TV or at the door
To make your computer to your TV, your computer must match an output to the TV. It usually has five types ofJacks or connectors are ports.they Composite / RCA (RCA) - One RCA connector, S-Video, VGA, DVI, HDMI.
Step 2: Selecting the right cable to connect your laptop or desktop to your TV.
1 Turn on the computer, and then take it to the TV. Unplug the monitor and other accessories for laptop, but always connected to the laptop keyboard and mouse.
2 Connect the video cable between the output from your computer to your TV.
3 Turn off the TV and set the inputs that correspond to these resultsThe TV. Maybe you need the manual for the TV to read how to do it.
Make sure that the screen size and pixel resolution of the TV and compatible laptop or desktop. Then you can see the video or picture on the TV. If the screen looks stretched, you will probably need to reset the screen resolution in Windows. However, the screen resolution automatically configured Mac laptop and conditions, if necessary, adjustments can be optimized in System Preferences. If Windows is unablenot be seen on the TV, it must again be your laptop or desktop control and the screen resolution before connecting to the TV.
Note Thu: VGA cable, DVI and component video signals do not support audio. However, no HDMI support audio, but do not support all HDMI-enabled graphics cards, dass
