I use a 14.1" Notebook computer and with an external monitor too. 1) I wish
to open one Excel Sheet in my notebook computer and another worksheet display
in the external monitor so that I read two files at full screen at one time
and also copy and paste data from one worksheet to another. 2) some excel
spreadsheet with many column, I wish to fully utilise the screen of my
notebook computer and also the external monitor. Can I see part of the
worksheet in one screen and then the remaining column in another screen
(extend the display size)
