Hi daveumali,

Have you tried updating your video driver(s)? or maybe uninstalling them and then re-install them?

If the Display driver update or reinstall doesn't help, update or reinstall the Lenovo function key driver which should be on the Support Downloads webpage for your model PC. There may even be a full software package for this to download and reinstall.
