USB VGA adapter
We recently added a USB to
VGA adapter to our product line. Before adding it, when I tested it
I honestly had low hopes, but I was pleasantly surprised. We had tested
several other adapters and found them to be unreliable at best. One of
the other technicians tested one that showed the right side of the
screen on the left side–so the sentence “Mary has a dog” would say
“ogMary has a d” We had essentially given up on the idea–I just assumed
that USB couldn't handle the VGA video signals.
The installation was simple, then I connected and powered on the
monitor and it automatically picked it up, I opened a word processing
document, and dragged it over onto the new screen. I expected a lag in
the display, but it worked as fast as I could type. I pulled up images
and other documents, everything seemed to work fine. I installed it on
a laptop computer, agian it was a simple installation and worked
without any extra ‘help.’ I tried playing a DVD on the monitor
connected through the USB adapter. I was actually surprised how well it
worked. The image wasn't perfect. It looked
â€œdigitalizedâ€ It actually reminded me of video clips on
video games. Smooth movements and images, but not quite realistic
textures. It wasn't bad enough to really distract from the movie. (for
me at least)
My primary concern with the adapter is that the drivers haven’t
passed Windows logo testing yet, so you see the error message that
notifies you and asks if you want to continue. The adapter uses three
different drivers, so when you first install the drivers off of the CD,
you see the message 3 times before you have even connected the adapter.
Once you do connect the adapter, it will actually install the three
drivers and so you will get the message three times again. That is
annoying, and some people might be concerned. I tested it on a desktop
system running Windows XP Pro, and on a laptop using XP Home both of
which worked fine, so I am not concerned that it will damage Windows.
Hopefully the drivers will pass the Windows testing soon. One of the
monitors ended up looking a little “washed out” colors weren’t a vivid,
but with the monitor’s image settings it was correctable.
If you want really high quality video on an extended desktop, you
will probably want to upgrade the Video
Card or for a laptop we also have the VT Book But this adapter gives you a portable and simple
extended desktop solution.
