TechBits: DisplayLink (4.25.12)

{} {} If you need a little extra room on your computer's desktop, it could be as close as your USB port. {}Many manufacturers are coming out with displays or display adapters that use a technology called DisplayLink. {}It allows adding the monitors without having to install a beefier video card.

{} {} There are some things to consider when using DisplayLink. {}Devices draw their power from the USB connection, so some require two free USB ports, as the power drain can be high (the second port provides additional power). {}Also, DisplaLink relies on graphics processing in the computer- so it may not be the best option for gaming and other graphics-intensive applications. {}DisplayLink is also limited by the bandwidth of USB. {}That means it's not ideal for driving high-resolution monitors.
