 Re: need help: dual monitor with a tablet PC, pen cursor ends up on other monitor
A mouse is using relative coordinate that cursor’s movement is based on the current cursor position. Mouse does not know what the display orientation is but moves by user’s control. The tablet is a pointing device and is using absolute coordinates; that is (0,0) at top left corner and (max_X, -max_Y) at bottom right. Therefore, the cursor goes to wherever the pen is pointing at and ignores the current cursor position. In your case, the primary display is at left and its origin is (0,0). The tablet PC is at right as a secondary display and its origin will be (1024,0). The tablet (input device) is a separate device from the monitor (output device); it is just happening underneath the tablet monitor. The tablet, likes the mouse, has no way to know what the display orientation is now unless is set by the user via a utility and device driver. You can call ”mapping” or “set tablet offset” utility that tells the device driver to reference an oriented coordinates. You can find a reference info at http://www.writescreen.us/downloads/2nd%20display%20and%20rotation.pdf this file. Your issue can not be solved by O.S. but only by the tablet vendor. Until then, your tablet cursor always goes to the primary display.   |
