MacBookPro crash, black lines in display

I have a 2011 MBP, I've recently started experiencing a problem of display problems/system crashing with black lines in the display. I hook my MBP to an external monitor for more screen real estate. I haven't seen this problem when the MBP is not hooked up to the display, so I think it may be related to the problem. What happens is: I am working on the MBP, then the screen becomes distorted, pixelated with black stripes, it looks like the screen has shifted a little too. Keyboard stops responding, although I still have networking because I can still ssh into the MBP. I basically have to do a hard reboot to get the screen back to working order.

Is this a known problem? It's happened 3 times this week, about once a day - I'm worried something on the MBP may be going bad. Any advice appreciated.

Try a hardware test.
Restart while holding Command-D (for diagnostics, eh?)
Run both the standard, and the extended test.
Do you get any error codes? Someone here can help you decipher them.

hmmm

I did run a hardware test (standard and extended) and the results were 'no trouble found'.

This was just concerning to me because it happened 2-3 times in the past week.

Can you use your MBPro for a week, without the external display attached?
If the problem occurs, even without the external, then you can go for a repair - should be less than 12 months old, so it's in-warranty.
If this ONLY happens with the external display, I would suggest trying a different video adapter.

If you read the OP - this is a 2011 model, which does not use Nvidia vid chips.
The 'famous' Nvidia problem is for models from 3 years (almost 4 years) back.
