Hi I discovered a row of dead pixels going across the middle of the screen after one day of use. I have the 15.6" Matte Full HD LED Widescreen (1920x1080) on the vortex IV and have read other people have had similar issues. Does anyone know if the problem also occurs with the AUO matte gamut screen as I can't afford to return the laptop a second time as I am at university abroad normally.
