I have been using a Samsung 24" SyncMaster 245B LCD monitor as the single display on my W7 system. I recently purchased a Samsung T550 LED TV/Monitor to use as a 2nd display. Specifics of my system are as follows:
ASUS Sabertooth 990FX AM3+ Motherboard
AMD Phenom II X6 1090 Processor 3.21GHz
MSI R6870 Twin Frozr II Radeon HD Video Card
Windows 7 64bit SP1
With the single display (Syncmaster) connected to the top socket of the video card with a DVI-D cable the desktop background was full screen and all worked normally.
When the LED monitor was connected to the bottom socket with a DVID-VGA adapter & VGA cable the computer did not recognize the monitor. The 2nd monitor was connected with a DVID-HDMI cable and both monitors recognized. The LED monitor is now the main display but now the desktop back ground is no longer full size with a black border 4” on the sides and 1” top and bottom and desktop icons are only shown on the main display monitor. The mouse does transfer from one display to the other. If the cables are swapped between sockets the display is the same. I have updated the video card driver to the latest version.
My goal when adding the 2nd monitor was to be able to work and between two documents or spread sheets at the same time. How do I configure the displays so that I can view different files from the HD or view email on one display and web page on the other or view two web pages?
