When i close my laptop: NVIDIA Display Settings are not available

[Rob D]

I might not have been quite clear on my post: my issue occurs whenever the laptop is using external monitors via the port, regardless of the lid ((but I have my built-in screen disconnected when the external monitors are on so closing the lid shouldnt impact the display driver. I had assumed mykdee311's problem was that when the lid is open the NVIDIA control panel can control the built-in screen, but when its closed there are no monitors its capable of controlling hence the error message.

Hello,

Disabling the Intel iGPU *after* having booted has zero effect on indirect displays because Windows uses the GPU used for POST (the one used before and during boot). Disabling in Device Manager will get black screens if the iGPU is really disabled or no change whatsoever because on some architectures it doesn't disable anything.

Unless nVidia changes their application, nothing is going to change.
DisplayLink technology works on nVidia and nVidia is a supported GPU. What the add-on nVidia software does has nothing to do with GPU support.

What is the value of that nVidia add-on application?

Alban,

Thank you for your reply. leavinga side what happens immediately after I disable teh onboard graphics card, if I rebooot the machine this is the situation I end up in (attached.) Is it (a) the onboard card has been disabled and the NVIDIA card is being used by everything, (b) the onboard card has been disabled but the NVIDIA card still isnt being used: the Dell (DisplayLink) adapter software is separate to bothy cards, or (c) Task manager is incorrect and the onboard GPU isnt in fact disabled?

Im hoping its (a), in which case it doesnt matter that teh NVIDIA control panel doesnt work because I dont really need it any more?

Thanks again for your help,

Rob

Incidentally, when I do this I do have one problem that when I start the laptop, it always changes my display settings from extending the desktop over 3 external screens with the built-in screen off, to duplicating the laptop and one external screen and extending it to the other 2. The problem of course is the external screen and built-in one are different resolutions, so I have to correct the setting every time. I dont have that problem when leaving intel card enabled.

Hello Rob,

Unfortunately, the screenshots seem too low resolution to be legible from my end.

Disabling in Device Manager doesn't switch off the graphics in the kernel at run-time.
Microsoft told me there was no point in doing so, any setting after boot is too late. It's about when the change is done regarding to the progress in the OS loading rather than when in time. It may change the behaviour for some applications, not for the OS itself. DisplayLink is not an application: we render pixels we get from the OS, we don't see applications, windows, menus or other objects.. we get computed pixels.
Have you observed any increase of general graphics performance after rebooting?

Upcoming Windows 10 includes a switch in the Windows Settings looking identical to some nVidia and Intel add-on application features. They blogged about it. I don't believe it works either on indirectly connected displays though yet. It's in the queue to be checked internally, but I haven't put it as a high priority as I don't see why it could possibly work.

We all need to keep pushing through the Windows 10 Feedback Hub to show it is important to us. Microsoft asked us to because this is how some new features are prioritised.

You are correct that today it doesn't fundamentally matter if the add-on app returns an error or not as it has no effect, but I feel it would be better if that application could start and understand a standard Windows feature introduced in the Windows 10 Anniversary Update. It most likely is a matter of priority rather than unwillingness to address.

Kind regards,
Alban
