I have a Fujitsu Tablet in a docking station that is connected to a Benq LCD monitor. The included Intel 965 chipset software enables the use of 'extended desktop.' I can do this from the screen (right click) or through control panel/displays.
All works fine and I have a scheme created 'docked.' When the screen saver activates, or I open Task manager, or I start the computer, the system seems to 'autodetect' and resets to the dual display clone.
I can right click and restore the extended desktop but as you can imaging this is a pain since all the open apps rearrange through the process.
I have emailed Intel and they have verified the drivers and software and it isn't causing a prob at their end. SO I have the latest updates to the Intel chipset etc. I have the correct driver for the Benq.
I even downloaded the Microsoft Hotfix for docking problems and external screens but still no success.
