Title:

Screen stuck on Low Resolution

Text:

Hi.

Video card is GeForce GTX 660M (if needed).

Upgraded HD to SSD and decided to refresh Thermal Paste as computer is 8 years old and hasn’t been open (screen adhesive seems to be original).  Now screen resolution is at 1280x720, everything is pixelate. Even Apple logo on startup. Going to System Preferences - Display shows Only resolution mentioned above. No Other Resolutions are listed.

Did I somehow damage Video card by reapplying Thermal Paste? I work in computer repair shop so have done it zillion times.

Thank you for taking a look.
