display continuously a pointer at the second pointer location and stop moving the pointer along the trajectory.

6. The apparatus of claim 5 , wherein the at least one processor is further configured to:

determine border edges of each screen of the plurality of screens based on the dimensions of the each screen, the border edges defining the each screen;

determine an in-contact section of each border edge of the each screen that is in contact with a border edge of another screen of the plurality of screens, wherein a corresponding border segment of the each border edge is determined by removing the in-contact section of the each border edge from the each border edge.

7. The apparatus of claim 5 , wherein the at least one processor is further configured to: in response to a determination (a) that the first pointer location is on a border segment and (b) that the trajectory is perpendicular to the border segment and not toward inside of a screen area defined by the border segments of the plurality of screens, display continuously a pointer at the first pointer location and stop moving the pointer along the trajectory.

8. The apparatus of claim 5 , wherein in the arrangement, each two screens of the plurality of screens are top-aligned, bottom-aligned, left-aligned, or right-aligned.

9. A non-transitory computer-readable medium storing computer executable code for operating a thin client, comprising code to:

obtain dimensions of each screen of a plurality of screens of the thin client;

determine an arrangement of the plurality of screens such that each one of the plurality of screens is in contact with at least another one of the plurality of screens and does not overlap with any other one of the plurality of screens;
