I have an HP monitor as my primary monitor, and purchased a 2nd 'Wise Wing" brand monitor to serve a secondary. I purchased a VGA splitter and hooked up both monitors, but the the new 2nd monitor is a mirror image of the the primary. I have set up one of these at work and in that instance the 2nd monitor only had an image of the wallpaper until I moved a window over to that area so that was I had an expanded desktop. In this case, I did the same thing. I right click on my desktop, selected "Properties", Display Settings", where I clicked on the "2" square representing the monitor and chose "enable" and extend desktop but no matter what I do it's still just a mirror of whatever I'm doing on monitor 1 so it's useless to have the 2nd monitor. One last note: unlike other times when I have done this as soon as I plugged in this 2nd monitor it came up mirroring the 1st monitor. The other time I installed (at work) the 2nd monitor was blank until I enabled it and when I did it was "extended" and not a mirror. I want to have a 2nd monitor that will let me move windows over to the 2nd monitor for reference while my working monitors are on the primary. How do I resolve this? Thanks.
