Do I need to buy an extra video card to run another monitor or can I buy a USB to VGA converter cable?

most modern video cards have at least 2 outputs.

if your computer is from best buy or similar, then you may need a video card in the first place to run 2 monitors

No such thing as a USB-to-VGA converter cable. Anything that appears to be one must have a tiny video card built into it somewhere. Not the best approach if you want the second screen to be capable of displaying anything more complicated than still images.

Seriously?! Stop giving advice in here ...

OP: There are shitloads of them on the market and they work wonderfully for most practical applications. We use the EVGA ones in our dispatch center, they have 5 monitors split between 2 computers.

I can't vouch for the performance, but he's right about there not being any USB-to-VGA ADAPTERS. They're basically mini GCs that you can plug in via USB.

Dude, seriously? Do you notice the large boxy thing on one end of each of those cables? Those are the video cards. They're just video cards that connect using USB instead of PCI Express. Yes, I'm sure they work fine, but they're not just "USB to VGA cables" like the OP thought they were. THAT is what I was clarifying.

USB 3.0 might have sufficient bandwidth to run a 3d-accelerated video card, but USB 2.0 doesn't have enough bandwidth. Keep that in mind when buying one of these.

Most modern computers have two adapters. I can hook up four with mine but I only use three. I have two NVIDIA Quardro NVS 280 PCI's and an NVIDIA GeForce2 MX/MX 400's. I dont game so they work fine for me. Plus, the Quadro's both have a double VGA chord.
