High contrast images stay on the screen S7-391

Greetings,

 

I just notice that images with high contrast that are displayed for long time on the screen stay visible on the screen for minutes even after the image changes, it's like if the image were burning the screen but they disappear after some minutes.

 

I have posted two images showing the problem on my skydrive:

 

Image 1: Normal desktop view

Image 2: Virtual keyboard opened showing the image problem on the screen, it's like if the keyboard were translucent but it's  not

This happens along all the border of the screen with high contrast images, I haven't tested if this happens on the middle of the screen, I'll soon.

 

Is this normal? Am I the only one with this problem? I'm using an Aspire S7-391

It's normal for this model. It is called screen retention but it is not permanent and never will be. It is a technique to enhance the contrast capability of the panel...a form of over-drive if you like. Personally I am not a fan of this and I haven't seen it for some years as contrast has improved natively on LCD panels that it shouldn't be neccessary. Anyway, the important thing to tell you is that yours is not faulty...its part of the design for this model.
