This question is an exact duplicate of:

I want to set up a system with two displays connected. One display will be a 22inch monitor with a native resolution of 1920x1080. The other display is a 19inch display native resolution 1024x768.

I want to clone the 1920x1080 display on to the 1024x768 display.

I have tried this and the 1080p image is squashed on to the smaller display. Is it possible to set it up such that rather than squashing the image, I can get the smaller display to use a virtual resolution of 1920x1080 and pan the display?

Windows mirroring demands that both monitors be of the same resolution.

The solution is a commercial product - UltraMon ($39.95).

From its documentation about Mirroring :

UltraMon offers a very flexible software mirroring solution:

  • mirror to one or more monitors
  • mirror only a single application, part of the desktop, or the area around the mouse pointer
  • zoom the mirror image or flip it horizontally and/or vertically
  • the source monitor can run at a higher resolution than the mirror monitor
  • pause mirroring (freezes the current image on the mirror monitor)
  • use hotkeys to start/stop/pause mirroring
  • source and mirror monitors can be driven by different video cards
  • To the downvoter : Windows has certainly changed since 2010 when this answer was written. Take some care how you distribute your downvotes. – harrymc Sep 13 '17 at 17:57
