How Can I Test For GPU Errors?
Have a late 2011 15" MBP don't know much of its history as it was an eBay buy.
Seller stated in listing that the video card was fried. Have received it and it seems to be up and running fine. If he hadn't mentioned it in his listing i wouldn't have thought anything was wrong.
I would like to test it to confirm if GPU is failing, so if there is any test or way to find out 100% could you all please suggest, thank you in advance.
