Cause
Resolution
The issue occurs because the operating system cannot immediately recognize the new monitor's properties when it resumes from hibernation.
When this happens the operating system forces a restore to the 4:3 resolution (1280x1024). This lasts until it identifies the new monitor's aspect ratio, and the temporary aspect ratio distorts the startup animation.
Rebooting or restarting the computer fixes this issue, since the new resolution is restored after a restart or reboot.
