hi
i got problems with my MSI GTX 970 on 8.4d. after last update from, i think, 1804 to 1903 windows 10 update my system not showing up brightness controls (laptops Fn keys not doing any trick) and even sleep mode gone from shutdown. also system runnning on my GTX 970, as i can see, but games have very slow fps rate (week before was all fine) and when i trying to get into nvidia control panel, its saying "you are not currently using a display attached to and NVIDIA GPU (i never had second one display). so i installed DDU and uninstalled all nvidia drivers (with all recommended settings). after i restarted, installed fresh nvidia drivers for gtx 970 and disabled dgpu (nvidia nvs5200m) in device manager. after next restart everything happens same - no brightness control (which restores when i launched fresh nvidia drivers installation) and control panel saying same thing. and when i switching to dgpu (which of course either nvidia) brightness controls returns. seems egpu working on some other display (which only one)? i deleted all monitors in device manager, but it not helps (even hidden one, which second, last one). any hints?

i have only one laptop's screen. I deleted all monitors from device manager - nothing changed.

It appears that your Intel HD 4000 is inactive or missing a driver. (Due to it being transparent in device manager and the display being connected to "Microsoft Basic Display Driver") Did you try updating the Intel driver yet? I also assume your Nvidia Optimus icon doesn't appear in the task bar?

 

Maybe try running DDU again with the eGPU disconnected and run it for both, Nvidia and Intel drivers. Also make sure to enable the setting to have Windows not look for new drivers. Make sure to use the latest Intel drivers from https://ark.intel.com for your CPU. Before reconnecting the eGPU reinstall the Intel driver (not sure how Nvidia drivers work for dGPU+eGPU setups and which version you need to pick there, but you might want to leave the dGPU driverless for now).

i have 2 dGPU - intel4000 and nvidia nvs5200, but when optimus engaged - intel 4000 is on, otherwise if optimus off - only nvs5200 on. i disabled Xeon PCI port in device manager, so its all time off (or getting 43 error on eGPU, which either Nvidia). so now i engaged optimus and both cards - intel4000 and gtx970 is working... but i need to set on every game to on it with gtx970 via advanced video setttings (which is not comfortable or game launching with dGPU)... before gtx970 was working with other dGPU nvidia fine with no error and no advanced settings on every game was required.... bloody update done the trick.. i already reinstalled all gpu's with DDU 5 times... same result...
its still strange, but if i disable intel4000 and checking on which adapted monitor working its said Microsoft Basic Video Driver... not gtx970.... when i turn it on (intel4000) and said it working on it... guess microsoft done some changes, maybe, in update, which affects it.

UPD:
I fixed it at last. just to disable some PCI ports through device manager, then enable Optimus, disable and uninstall dGPU Nvidia and reinstall eGPU. and then last drivers. via nvidia control panel activate default adapter for 3d apps which more high powered. and it worked. thanks all! topic can be closed.
