    everything was fine until i turned my back and went downstairs for 20 minutes.

    when i got back, the screen looks like this (i used an empty white desktop to make the problem easier to see)
    the photo is rather crap, but if one could imagine a row of spotlights placed against the bottom of a wall and all shining their beams up the side of the wall is the best i can think of to describe the issue.

    there has never been any problem with the screen.

    2013 mbp 15"

    i have tried rebooting
    reset pram
    reset smc

    any ideas ?

    Some video distortion problems have been attributed to dGPU problems with 2013 MBPs. I do not know if your MBP has a discrete GPU, but if it does and it becomes a problem then the logic board would have to be replaced. Apple has an extended Warranty replacement program for that failure. See MacBook Pro Repair Extension Program for Video Issues.

    You may need to make a Genius appointment at an Apple Store for an evaluation if you want to pursue a video problem.

    looks like you lost some backlighting, but i'm not sure how the backlights in that machine are laid out. Does changing brightness have any effect?
    Here's hoping you are still under AppleCare!

    The backlight is defective.

    at the screen's brightest, the fault is the least "offensive", dimming the screen makes it worse.

    odd that it suddenly happened in the 20 mins the mbp was unattended
