A Dim Laptop Screen Picture
If the screen is very dim and altering the brightness does not make any or no difference then your laptop could be suffering from a back light problem or issue or even be causaed by a faulty inverter if it is an older laptop. Most newer laptop models are now LED screens so backlight problems are no longer much of an issue.
If the screen suffers with any areas of little coloured dots or black and white dots that are on screen all the time this could be a sign of dead pixels. In this instance there is nothing that can be done except replacing the screen. One or two dead pixels is deemed an “acceptable” fault for most manufacturers but if there were a lot of dead pixels, an extreme case of 15 for example, then the manufacturer would probably replace the screen under warranty.
If you notice that your laptop screen is flickering or showing different patterns when you move it, this could be a bad connection but more than likely is a faulty screen. If the picture display flickers as soon as you even move the lid or even if it flickers when you are not touching it this can indicate a loose connection or a faulty laptop screen.
