Good morning. With the latest Windows update (8.1 Pro) on June 17th, my display dimmed and could not increase brightness. I could dim it to a black screen with the various controls. After a few other troubleshooting attempts, performed a system restore to date prior to update and dimming issue went away.

Has anyone else noted this? Could this be a driver problem that also will need an update? Does anyone know what I might need to do before I allow this system update to be installed?

Thanks.
