What application is recommended to find dead pixels on LCD panel?












3















I suspect there are few of hot pixels on my panel. As it is still under warranty and by the rules of my vendor I can replace a machine if panel has a 3 dead pixels on it, I'd like to check how many dead pixels there actually are.
In Windows, there are plenty of simple applications that just fill the whole screen with different colors so hot/dead pixels are easily visible. Does something like this exists for Ubuntu?

              You could use GIMP Image Editor to make 4 images that are the same size as your desktop and color them red / green / blue / white.



              Then open them in Image Viewer ( default picture viewer ).



              Then dual click on the picture to get it full screen.



              GIMP Image Editor is available from the Ubuntu Software Center



              Following is a How-To for the visual learners.
