Currently, I had problems with mouse movement. To avoid it, I must set special resolution on some screen and set 0.75% scale. That do not solve my problem in 100%.

Solution is to add option to merge screens to columns/rows (if possible). In this case, moving mouse from one column to another will teleport/map cursor on the same y/screen_height of source column to corresponding coordinates of destination column. Similar solution we could use for rows.

Problem with mouse movement was: when I move mouse from bottom of one screen to another, mouse will stay of previous screen, until I do not move on y axis.
