Can't make the slim Samsung laptop work with an extrenal monitor

Hello,

This is for a Samsung ATIV Book 9 Lite (NP15S3G-K01US),

I have purchased this machine for a high-end executive of the company I work for and we do not use Windows 8, so I was forced to downgrade this machine to Windows 7 so it would be compatible with our network.

The machine is working great and the Executive is very anxious to receive it. However, the biggest problem that I have had is that I am unable to correctly connect any external monitor to the device.

I have purchased a third part USB-to-VGA cable and while the machine DID detect the device, it said that there was a problem. I tried to run the actual software that came from the manufacturer (j5) and it said there was an error with the WDDM on the graphics card. I looked at the graphics card via Hardware ID and I found that it is a Raedon HD 8500 which IS Windows 7 compatible.

I next tried the official Samsung micro HDMI-to-VGA adapter and nothing has happened. The computer does not recognize the device and nothing new is appearing in the Device Manager.

Please help....
