We’ve talked before about having more than one monitor. If you have two monitors, but only one video card… it can get quite expensive to buy another card. Well, now you don’t have to!

Lewis wrote to me from SewellDirect. They have a device that can save you money, and make use of any available USB port on your computer! With the USB to DVI External Video Card, you can easily connect more than one monitor, while having only one onboard video card.

The USB to DVI supports up to six simultaneous displays, including widescreen displays, extending your desktop and your horizons. Adding a quality DVI or VGA high resolution display through your USB port used to be science fiction. It is now science fact with the USB to DVI-I adapter. With onboard memory and video processor, it is really an external video card you attach to your computer with a USB cable.It used to be that you could add a display via a USB port, but the refresh rate and video quality was lacking. With this USB to DVI display adapter, complete with VGA adapter, you can add either a DVI or VGA display that behaves just like a monitor connected to a standard video card. It operates at a high resolution of 1600 x 1200.

DVI vs VGA

http://live.pirillo.com/ – Quill in the chat room wants to know if there's a way to convert a DVI connection to VGA or, failing that, a way to convert an S-Video port to VGA.

First, don't bother trying to convert S-Video to VGA: it's just not going to be a good experience for you.

If you need to convert DVI to VGA, just pick up a DVI-to-VGA adapter. They're generally pretty cheap – so cheap that most video cards come with a free adapter.

What's the difference between DVI and VGA? DVI is a digital connection, whereas VGA is an analog signal, so you get a slightly higher quality signal with DVI than with VGA.

Generally, you'll find DVI connections on LCD monitors as they handle the video signal in pure digital form, while CRT monitors will use VGA because the video signal remains analog through the entire monitor.

Do you have any recommendations for a good DVI-to-VGA adapter?
