I'm using a 39" HDTV as an extended monitor to my HP Elitebook. When I open a file, such as a spreadsheet, and view it on the HDTV, I want to maximize the size on the screen, but when I click on th maximize button the image goes beyond the viewable limits of the screen. I cannot figure out how to change setting for the extended HDTV monitor so that the files will display to fit the screen only. Any suggestions? I'm running Windows7.
