My wife’s notebook one day got a blank screen. I tried plugging an external monitor and it also got “no signal input”. I can hear the windows booting/login sounds on the speakers, so I know the system is running. Pressing the “usual key combinations” to switch screens didn’t do the trick. I supposed that it’s an issue with the internal graphics card, so I bought the external USB Display Adapter hoping it would be fully plug-n-play (including boot-time BIOS screens), but screen still was blank (led didn’t switch on too). I could hear windows “usb plugin” sounds detecting something. I transfered the adapter to my desktop computer, and, after booting windows, I had to enter device manager, click USB-DVI device and request “Install Drivers”. It installed beautifully with no further interaction, and worked with a second screen. I even switched it to be the “sole” screen of my desktop for testing. It is good.
Questions are:
- Do I need a working graphic adapter to use the USB adapter? (I was hoping it would function standalone as primary display card of my wife’s faulty notebook)
- If it can be the primary card indeed, do you have any advice how can I install it on Windows, since I can’t see anything on screen before it is working? (funny eh?)
