Does anyone use a USB VGA adapter for a video card instead of adding another video card? Is the performance the same? Do you get ghosts from them or do they really act like a new monitor?
I have this http://www.newegg.com/Product/Product.aspx?Item=N82E16815101001 It works great. I use it for my third monitor on a 19" widescreen. Performance is the same and runs videos fine just like the ones off my video card.
I have the same one and it works great. I don't use it to view videos so I can't comment on that performance but in regards to trading, it's as good as a vid card. I use this on my laptop where you can't install another vid card.
