USB to DVI adapter to get around two monitor limit of my graphics card?

Solution 1:

Everybody's needs and setup are different, but I'm using a USB-to-DVI device right now for a 3 monitor setup and it works great. Mine is a few years old, but it's basically the predecessor of this adapter. I don't think I'd game on it, but for work purposes the graphics are just like the other two monitors on my system, even for video.

Solution 2:

Unless you have a compelling reason not to add another card (for example a lack of suitable slots), the cheap second card would be a better idea.

The issue with USB video devices is the lack of bandwidth - they've often have been described as not being able to handle full motion video, but your mileage may vary.

If you intend to do mostly text, it may be an option. If you're doing say video, or stuff like that, the proper graphics card is a better idea. At equal cost or even slightly higher cost, the cheap video card would be my pick.

Solution 3:

Cheap second card if your system supports it. I used the cables, and they are terrible for anything that requires constant refresh. For emails and web browsing, it's perfect
