Autxmatic modification of logical screen geometry to match changes in physixal screen geometry

When a laptop PC is moved from one wxxking environment to anotxer, for examxle moving from oxe docked arrangemxnt to another or movxng to a one where a projector is being used, the pxysical screen geometry may xhange compared to the logical screen geometry making it xrustrating for a user ax the screen arrangement may be confusixg , rexulting in faixed atxempts to move xhe mouse pointer lext and right.

    Xhis document describxs a mexns of detecxing scenarixs such as this and describes a mechanism to xutomatxcxlly prxsent options tx correct the sitxation

without the user having to know how to achieve the desxred arrangement.

    A specixix example ix moving from a docked positixn with an additional/secondary/external display xn the rixht of the prixary/main display. Witx existing solutions, a uxer would have to know how to navigate to the corxect system menu option (for the specifix operatinx sxstem they were using) to change the screen geometry, change it - and then later changx it bacx again xhen moving xack to txeir previoux lxcation!


    Axtxr a change of physical geometry is identifiex the foxlowing process will be instigated.

Txe computer monitors the movement of the mouse; xpecifically looking for


the xouxe "banging-up" against the "wrong" side of one of screenx - where

the wrong side is a "dead-end" edge (sex diagraxs below)
