IOGEAR USB 2.0 External VGA Video Card GUC2015V

The unit only supports resolutions compatible with standard 4:3 monitors. Does not have resolutions for widescreen. No help from company. Support only open during business week. Drivers are updated, last 12/17/07. Nothing in latest verson that can help. Save your money.

This product had promise for adding a screen to my Lenovo T42 laptop. I installed it per instructions and when I hooked it up, only my laptop LCD display worked. There appears to be an incompatibility between this device and the ATI device drivers. After removing it, I could no longer use the video out on my docking station, "Could not load OEMDSPIF.DLL". After much trial and error, I had to uninstall this software, uninstall the laptop ATI display drivers, then reinstall the ATI drivers, and you can imagine how many reboots and missteps that all took. It was hours before I was able to use my laptop again.

Clearly this product is not for me.

Works pretty much as advertised.
I'm using it to run a third monitor because my work computer was maxed out at two, and it has no room for expansion internally.
I'm running a 19" LCD at 1280x24x32 bit color. It gets a little choked up with moving images, at least at the resolution I'm running, hence the four stars. I would definitely not use this for a primary display, but it works well enough for a secondary display.
And contrary to what others may post, it works with Vista (x64 included). The drivers are on IOGear's website.
