17-inch MBP video errors
Some buyers of the recent 17-inch unibody MacBook Pro have been experiencing a severe graphics error, discussion at Apple's support forums suggests. The error manifests mainly in the form of green lines, though these can be accompanied by speckles. It also appears to be independent of a specific application, though it is thought to be more likely to occur during intense functions such as gaming.
Apple has yet to make an official statement, but the company is said to be offering affected people a replacement notebook. The source of the difficulty may be NVIDIA's GeForce 9600M card; switching to integrated 9400M graphics offers a temporary solution, and similar issues have plagued earlier NVIDIA-based MacBooks. If true, it may be possible to resolve the problem through a future firmware update.
