Hi,
I had made my LabVIEW vi window Size to 680X480 in properties & developed the control under this size.
Than I make out Executable & installer for the same.
I run that installler on my 680X480 resolution monitor & it works perfect as i have few control & indicators on front panel.
you can set your screen resoltion in win7 by going into Advance setting for screen reslotion.
