Yoga 3 Pro 1370 Brightness and External Monitor Problem

My daughter has a Yoga 3 Pro 1370 that has a problem controlling the brightness. The brightness is on full and cannot be changed via the keyboard or via Microsoft Mobility Center. There is also a problem connecting to an external display (no display is detect). All this use to work as recently as 2 days ago. The OS is Windows 10 64-bit April Update 1803. The current HD Grpahics 5300 driver is 20.19.15.4642 (3/22/2017) and the monitor driver is Generic PnP Monitor 10.0.17134.1 (6/21/2006). I tried updating both but it says these are the latest drivers. There is no driver rollback available (greyed out). The Lenovo graphics driver (10.18.15.4278_PV) and the latest Intel HD Graphics driver (15.40.38.4963) would not install (indicating not validated for this computer). I also ran the System File Checker and everything is fine. Any help/solution with these problems is greatly appreciated. Thanks.

Re: Yoga 3 Pro 1370 Brightness and External Monitor Problem

Well, I got no help in this forum but the problem was in Windows 10 Version 1803. A cumulative update on 9/13/18 fixed the brightness control problem. The external monitor problem was due to a bad micro HDMI cable.
