Brief Problem statement regarding the problem of the display screen in the imx53 board.

The mouse pointer in the case of touch screen is not according to the point of contact. Please refer the video attached with this mail for an understanding of the problem.

The mouse pointer in the display screen matches with the point of contact only at the centre of the screen. As the contact point is moved further to the centre the mouse pointer lags the contact point. Under this situation the touch screen will only work if click is occured at the centre of the screen and the furthest point of the display screen cannot be accessed by the touch screen.
