What does this error means?

Hi all

Just ran several times Apple Diagnostics - and got this error:
4VDC/1/40000003 VideoControler
What does this Means - I never got any issues with my MBP even in Vista running latest 3D shooters

Might be a bad GPU. See if it qualifies for a free replacement. I've swapped out so many boards for this issue I can whip one out start to finish in under 45 minutes.
