A third screen that I connect using the USB->DVI adapter appears as “No Monitor” on the screen resolution menu.
My system has an NVIDIA GEFORCE 9400 T (Dual Head DVI) as my graphics card, which works fine with the two DVI connected, 1680x1050 screens already connected.
When I attach the Plugable adapter, it appears to install properly. I restarted the machine as requested. Then I go to the Screen Resolution screen and choose to Detect the screens and then select the third monitor (using VGA adapter) with resolution 1920x1080.It appears as “No Monitor” in the pulldown menu. If I apply these settings (to extend the desktop to this screen), the third screen appears with the desktop extended but the image is very dark.
Note that this seems to be a hit and miss proposition. If I disconnect the adapter and then try using HDMI, it appears as FPD Monitor in the pulldown and appears as expected on the screen (though it is cut off slightly at the top and bottom). Then, I disconnect from the HDMI and reattach using the VGA adapter and it works (as long as I don’t shut down). If I shut down and restart, it is back to “No Monitor”.
Please let me know if this issue is something do to with my system, a bad unit or if I am doing something wrong in the installation. When it works, it is great! But, having to go through that process each time I want to use the third screen is frustrating. Also note that I would like to use the VGA connection on the HDTV I have as HDMI is being used by the cable box.
Thank you and let me know if there is anything else that you need to hopefully resolve this.!](https://sslproxy.getsatisfaction.com/sslproxy/SWhAdDNLMG5zdGFuVGlWenmLbJDGd3CABhjZermgcystANA4T6nd0pzV0fSzBRRGOd17A4b8ZLwi6-HESbXI0nQ2UVQUxLQLH7VMvm7vCNkQcHPG0Q2JvdPM9X75bZyk9MrU2n5y-QrKRbzqD4AZfQ==.jpg)](http://s3.amazonaws.com/satisfaction-production/s3_images/348530/No-Monitor.jpg)
