Mulitple Displays

Recently I wrote a blog on the use of travel monitors so even when you’re out of the office you can have multiple displays. Now while in the office I use three monitors, one is my laptop screen, and two external monitors. Now you may ask, “how do you have two external monitors attached?” as laptops only have one VGA port available. The answer is simple, I use a USB video adapter for my third screen. I’ve tested a number of these from makers such as Iogear, StarTech, Kensington, and HP. The problem with a lot of these USB video adapters is the resolution isn’t always the greatest because of the hertz rates they use there can be frequency issues so you’re seeing the screen flicker or streaming lines also you may experience slowness when moving items on the screen. This hardware uses the DisplayLink software to simplify how multi-monitors talk to each other.

I have been using the HP external video adapter (Part: NL571AA) for the last year and a half and I have to say it works great! The resolution is amazing; I experience no slowness, and no flickering. Priced between $49 and $79 the unit is a must have if you’re in need of multiple screens and are a laptop user or even a desktop user and don’t want to hassle with installing a video card into your machine. At home I have to of the adapters installed so that I can use 4 screens on my desktop!
