184.108.40.20628 seems to be an OEM driver as I do not see it posted in our web site (at least no longer on it).
Using our generic drivers, versions 3257, 3165 or 3071 @ Download Center,have you checked which display is set as the primary display in that configuration?
Or when you have that "black screen issue", have you tried pressing the designated key in your keyboard to toggle between the screens? (the key or combination of keys may depend on your Original Equipment Manufacturer, and some systems do not have that option)
In addition, have you tried updating your system BIOS and set defaults on it?
