Disable the launching of control.exe on new device detection on Windows 7

[willn]

Hello,

We're using version 7.9 M7.

Is it possible to prevent DisplayLinkUI.exe from starting the control panel when a new device is detected? I saw the following registry values:

HKEY_LOCAL_MACHINE\Software\DisplayLink\Products\D isplayLink Graphics\OnNewDevice /v Launch

HKEY_LOCAL_MACHINE\Software\DisplayLink\Products\D efaultProduct\OnNewDevice /v Launch

Are these relevant?

Thanks very much

Hello,

Would you mind sharing a screenshot of the panel open?
7.9 is not recent and I would like to make sure I'll be asking about the correct thing,

Kind regards,
Alban

Hi Alban,

Yes, this isn't a screenshot from my machine (I just found it on google), but this is the same control panel page that appears:



Thanks very much,

Hmm, apologies if this ends up getting posted twice, I submitted a reply a few days ago but it's yet to appear.

This is not a screenshot from my machine but this is the same settings page I am describing:

It is the window that appears when you type the following command in cmd:

control.exe desk.cpl,,3

Thanks,

Will

I should have said, we are using Windows 7

Hello,

Yes, the value of WDP matches what is being open (Windows Display Panel) to configure the display layout.

Could you try removing the "WDP" value?
This is rather ancient code, so I am having issues finding documentation.

Kind regards,
Alban

Apologies for asking support on an old version, we are hesitant to upgrade as we have a stable embedded system where updating drivers introduces considerable risk.

Does this behaviour occur in newer versions?

I have tried removing the Launch value entirely, but it made no difference. I also tried replacing the string "WDP" with "URL" (based on an error string in the DisplayLinkUI.exe binary it seemed like it might be a valid option.)

Kind regards,

Will

Hello Will,

That's totally fine, it's more the Windows 7 we see much less of now and the driver architecture is radically different.

I need to find an engineer who's been here a while to understand the functionality and options.
Judging by other keys, maybe the value false works, but that's a shot in the dark until I get someone who knows or can look at the code.

Kind regards,
Alban

Hello Will,

Looking into more details a colleague has advised me to delete the full folder (OnNewDevice ) instead.
Removing only one key is likely to mean the default values will be used.

Kind regards,
Alban
