I have been researching and have been unable to find my answer. My former employer used dual monitors on their computers. Each time a window opened, next to the "minimize" "full screen" and "exit" buttons, there were two additional buttons for the option to send that program window to the "other monitor" or "stretch between both monitors." I know this is probably a poor explanation, but hoping I can get some help. I do not know the video card from my former employer. However, my video card is nVidia GEForce 8400M GS and would like to add it to my computer. I looked at the nVidia site and unable to get an answer.
