Hi. I own a DVD kiosk. It is run by one computer and has two screens. One screen is a touchscreen (rental screen). The other is just a monitor (plays trailers/previews/ads). The monitor screen is not getting a signal. It is not a bad monitor or a bad cable. I have narrowed the problem down to the VGA (blue port) on the back of the computer. My question is this: Can I bypass that VGA port and run a VGA (back of monitor) to USB (on computer) cable to get the video signal to the monitor? I have inserted a link for a page that has what I think I need, but I am not sure if it will work or if this is actually what I need.

Any help is appreciated. Thank you.

Those USB to VGA/DVI adapters are basically just self-contained video cards. It would be better to replace the internal video card. Can you identify the GPU?

Ok, I am sooo not very knowledgeable about this stuff. I know the graphics card is a e-geforce 5200 128mb PCI. The port that is not working is not the same port that is connected to the actual graphics card. Does that make a difference. I know it may not be ideal, but would a VGA/USB adapter solve my problem? Would I need USB to VGA or VGA to USB? Does it make a difference? Thanks for the help.

Oh, so you're using the onboard video for one display?
If you have another expansion slot available, it would be far better to add another internal video card due to bandwidth issues with USB. A USB to VGA adapter will work, but you should not use one unless it is your only choice.

USB: 60MBps
PCI: 133/266MBps
PCIE x16 2.0: 8GBps
