split screen with grey bar

Any ideas of what's going on here with this sort-of split screen? Trying to get my nephew up and running again. Thanks!

Is it broken? It looks like a dead display

Hardware problem, looks like.

I agree. Not a split-screen, but a defect/damage to the screen, basically a "dead" region.
If you log in to the Mac, and do normal things, does that area stay the same, regardless of what else is on the screen?
