To resolve the issue temporarily, you may need to reset NVRAM. Once you can use the display again, download and install Mac OS X 10.4.8. You can use the Software Update feature of System Preferences, or download the Update from Apple Software Downloads.

If you have updated to Mac OS X 10.4.8 and the issue still seems to occur, you may need to reset NVRAM on your MacBook again.
