US company DisplayLink, in co-operation with Alereon, has developed a reference model for the wireless connection of monitors with computers.

This development uses wireless USB technology called "Ultra Wide Band". The graphics adapter used allows PCs to be connected with conventional monitors via a wireless link, which means that no cable is needed.

The device uses the AL5000 chipset from Alereon in combination with the technology developed by DisplayLink for network monitors with USB connections. The company already presented a solution at the beginning of the year which allows numerous monitors to be connected to one Vista PC via USB, without the need for each monitor to have its own graphics card.

The manufactures are promising a maximum resolution 1,680 x 1,050 pixels for wireless transfer, with the potential to display 16.7 million colours. The bandwidth of the wireless connection would be sufficient to play back DVDs without juddering.

"If a monitor is connected using our technology, it functions like a monitor connected via cable for the user ", explains Hamid Farzaneh, CEO of DisplayLink. "Given the growing popularity of wireless mouses and keyboards, the availability of a technology that would grant a monitor the same freedom is exactly what OEMs need to create explosive growth within this market ", Farzaneh continues.

The solution is to be officially presented by both partners at the Consumer Electronics Show 2008 in Las Vegas at the beginning of January. It is not yet clear how fast the development will be deployed in relevant products.


The technology is to be made available to hardware manufacturers who are to develop their own models based on it. At the moment, monitors with USB connections are still quite rare. It will still be some time before they can be provided with data via a wireless connection.

The DisplayLink technology has been applied in the Samsung Syncmaster 940UX, which can be connected to a PC via USB. Upon the initial connection with the computer, the driver data is loaded and the screen is integrated into the system. (Source: pte)
