RE: Alienware Laptop has vertical flickering pixels across the screen

Hi PEEWEEDAPLUMBER,

What is the exact system model? Is the distorted screen persistent or random. Does the system overheat? When do you encounter the screen distortion?

Connect an external monitor and check if it works fine. 

Run the LCD bist - Turn off the system and press and hold the "D" key + power button to turn on the system and it should run the LCD built in self test - see this link for more info - http://dell.to/1SkXNrG

Restart the system and press f12 key on startup - choose diagnostics. Let it run the diags and if you encounter any errors - make a note of the complete error and report the same to us.

Restart the system and press f2 key to enter BIOS and check if the distortion is seen there as well.

If the system is under warranty, write me a private conversation with the service tag and your contact details. If there is no warranty, then we can help with a paid service call if required.

Keep us updated.

Thanks and Regards,
