What does the Video System Test (VST) assist in identifying for the MacBook Pro (15-inch, Late 2010)?

The Video System Test (VST) is designed specifically to diagnose issues related to the display and graphics functionality of the MacBook Pro. It is particularly effective in identifying intermittent display freeze problems, which can be indicative of underlying hardware faults, such as issues with the graphic processor or connections between the logic board and display.

This testing tool can help technicians determine if there are failures in the video signal path or if the graphics hardware is struggling under certain conditions, leading to freezes or unexpected behavior during use. By focusing on these symptoms, the VST allows for targeted troubleshooting, ensuring effective repairs or component replacements can be carried out to resolve these specific display-related issues.
