My screen is glitching, double vision. Why?
So my screen is sorta glitching upwards and I have no idea how to fix it. This happens randomly and goes away randomly too.
Try connecting an external monitor to the laptop and check if the problem occurs on it as well.
If not it may be a loose or faulty video cable between the motherboard and the LCD panel or a faulty LCD panel.
If it does, does it happen regardless of which GPU is being used? (I think that your model has an Intel and a Nvidia GPU, is this correct)?
