Download latest build here #115

MolotovCherry · 2024-04-09T18:11:52Z

The latest master build has a lot of features and fixes, and is stable.

Between the current stable release and latest master, these are the following feature changes:

no admin access required for state updates to driver (cli tool, python bindings, or future gui)
working cli tool (thanks @kylewlacy!) (set NO_COLOR/FORCE_COLOR env var to disable or force enable colors)
optimized performance when under high cpu load
lots of miscellaneous improvements and fixes
hardware cursor support (for remote desktop apps, this is a big plus!)
up to 16 monitors (minus your only existing monitors, usable number might be slightly lower)
complete bindings for rust, and python (python 3.7+)
- examples on how to use it are here
windows service which does the job of starting persisted monitors on boot (disable or don't install if you're not interested in persistence)
- place vdd-user-session-service.exe wherever you want
- run as admin .\vdd-user-session-service.exe --install to install service
- to uninstall, run as admin .\vdd-user-session-service.exe --uninstall
- (you must keep the exe at the same location, otherwise the system won't be able to find it. if you want to re-locate it, uninstall the service first, move to new location, then reinstall it)

Note: there is currently no gui in master release
driver.zip - updated 10/16/24

To install:

uninstall the driver completely
Follow the manual driver installation steps here (you can skip the registry file step, and skip certificate step if certificate is already installed)

Didnot see the vdd-user-session-service.exe in the folder

Didnot see the vdd-user-session-service.exe in the folder

@psychrabi How did you download it? I see it in the zip from the provided download link in the post

psychrabi · 2024-05-27T07:11:54Z

I redownloaded the driver now and i see the service.exe now

fabiomilson · 2024-08-18T04:56:57Z

The download button on the job is not showing, why? I can't download the driver :(

Where is the documentation on how to use vdd-user-session-service.exe? The help flag isnt really telling much either:

 .\vdd-user-session-service.exe --help
Usage: vdd-user-session-service.exe [OPTIONS]

Options:
  -i, --install    Install the service
  -u, --uninstall  Uninstall the service
  -h, --help       Print help
  -V, --version    Print version

MolotovCherry · 2024-08-30T15:55:38Z

.\vdd-user-session-service.exe --install

@tristan-k As it says in the first post:
As admin, run .\vdd-user-session-service.exe --install to install it
To uninstall it run as admin .\vdd-user-session-service.exe --uninstall

yaole-A · 2024-08-30T15:55:51Z

.\vdd-user-session-service.exe -i

tristan-k · 2024-08-30T15:58:44Z

So vdd-user-session-service.exe is just for installing the service but how do I create and edit virtual displays?

yaole-A · 2024-08-30T16:00:11Z

Will HDR be added to this latest driver later?

yaole-A · 2024-08-30T16:01:03Z

use the cli.exe to add monitor

MolotovCherry · 2024-08-30T16:04:10Z

@yaoleiliu I'll look into HDR when I have time, but right now there's no ETA since I've been very busy.

@tristan-k Use virtual-display-driver-cli.exe to control the virtual displays. How to use it is displayed in the help commands, including subcommands.

.\virtual-display-driver-cli.exe --help
.\virtual-display-driver-cli.exe <subcommand> --help

tristan-k · 2024-08-30T16:11:41Z

Thanks. I just installed the certificate with .\install-cert.bat, the service with .\vdd-user-session-service.exe --install and then tried adding a virtual display with .\virtual-display-driver-cli.exe add 1920x1080 but I do get an error.

.\virtual-display-driver-cli.exe add 1920x1080

you need install the driver after install-cert.bat

Okay, so the prodecure is:

.\nefconc.exe --remove-device-node --hardware-id Root\VirtualDisplayDriver --class-guid "4D36E968-E325-11CE-BFC1-08002BE10318"
.\nefconc.exe --create-device-node --class-name Display --class-guid "4D36E968-E325-11CE-BFC1-08002BE10318" --hardware-id Root\VirtualDisplayDriver
.\nefconc.exe --install-driver --inf-path ".\VirtualDisplayDriver.inf"
.\install-cert.bat
.\vdd-user-session-service.exe --install
.\virtual-display-driver-cli.exe add 1920x108

.\install-cert.bat
.\vdd-user-session-service.exe --install
.\virtual-display-driver-cli.exe add 1920x108

no
the prodecure is:
.\install-cert.bat
.\nefconc.exe --remove-device-node --hardware-id Root\VirtualDisplayDriver --class-guid "4D36E968-E325-11CE-BFC1-08002BE10318" .\nefconc.exe --create-device-node --class-name Display --class-guid "4D36E968-E325-11CE-BFC1-08002BE10318" --hardware-id Root\VirtualDisplayDriver .\nefconc.exe --install-driver --inf-path ".\VirtualDisplayDriver.inf".\vdd-user-session-service.exe --install .\virtual-display-driver-cli.exe add 1920x108

.\install-cert.bat
.\vdd-user-session-service.exe --install
.\virtual-display-driver-cli.exe add 1920x108

If you installed the driver before installing the certificate, it will cause a system error. To fix that, you need to completely uninstall the driver again, make sure the certificate is installed, then install the driver again.

(What yaoleiliu said is the correct procedure)

.\install-cert.bat
.\nefconc.exe --remove-device-node --hardware-id Root\VirtualDisplayDriver --class-guid "4D36E968-E325-11CE-BFC1-08002BE10318"
.\nefconc.exe --create-device-node --class-name Display --class-guid "4D36E968-E325-11CE-BFC1-08002BE10318" --hardware-id Root\VirtualDisplayDriver
.\nefconc.exe --install-driver --inf-path ".\VirtualDisplayDriver.inf"
.\vdd-user-session-service.exe --install
.\virtual-display-driver-cli.exe add 1920x108

Got it. Now it kinda works. Though I'm still unable to connect to Sunshine because I'm using gpu partitioning with hyper-v and ran into an issue . According to the sunshine devs the display has to be connected to the GPU. But this is a different issue proably not related to this project.

Followup question: Is there an easy way with nefconc.exe to uninstall the certificates previously installed?

MolotovCherry · 2024-08-30T19:26:20Z

Followup question: Is there an easy way with nefconc.exe to uninstall the certificates previously installed?

@tristan-k No, nefcon is only for drivers. You have to go into "Manage User Certificates" or "Manage Computer Certificates" and manually delete them.

There's a guide on how to manually install them here. You can just instead find them in those locations and remove them.

Hi there, thanks so much for this program; it's working much better than my old dummy HDMI setup.
The link for the new version has expired. Could you please renew it? I really appreciate it.

@bb12127 Sure thing! Check here once build finishes

From now on I will just attach the artifact to the page to make it easier, and so it doesn't expire
