I wonder if anyone else has had issues trying to install this device manually with device manager. I've tried this while running device manager as an administrator and ran the bat file first. Even after rebooting I still get

"An error has occurred during the installation of the device."

I hope something can be done, it'd be lovely to enable a few extra monitors for VR use.

Sorry for making an issue for this, but discussions are disabled. Anyway... how exactly did you get https://github.com/akatrevorjay/edid-generator to create an EDID with multiple display modes? It seems to me like it only supports building an EDID with a single mode. Or am I understanding this wrong and windows gets the mode list for settings from something different?

I have installed the IddSampleDriver on 2 versions of windows on the same machine, the first one on an original installation of windows worked perfectly, but the second one is a tweaked windows called AtlasOS, and even through all other apps and services have been working so far, the driver install the certificate rightly but when I install it gives me code 19: "Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)" I have tried to uninstall the driver and install again and many other already given solutions on the others issues but nothing seems to work, and I have no idea on how to make it work as a virtual monitor became basically essential to some of the tasks I do daily, so if anyone can help I'm going to be very happy about it.

I'm using this to try and get Parsec working on a headless computer, and after installation I set the resolution of the virtual monitor to the same as the monitor I had temporarily attached (1920x1080) and set it to duplicate, as I assumed (wrongly, it appears) that it would need to be that way for it to show the "normal" display on the virtual one for Parsec to use. But every time I try, it just resets it to an extremely low resolution, which makes everything big and messes up all my windows, which are now all resized very small and moved around when I revert back to extended vs duplicated. This is on a fairly recent Win10 ver (21H2 I think) and a GTX 770 with updated drivers outputting via HDMI to a FHD monitor, using the latest version (0.0.1.2) of IddSD.

See https://github.com/roshkins/IddSampleDriver/issues/26. Pointed the fork to the main page instead of in the releases as I have added important information in the readme.

Device Manager reports this in the device status. "This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)

The ALPC message requested is no longer available." If it helps, I'm running on Windows 11.

This works well, but I have two issues. I can only scroll through 3 resolutions, 1920x1080, 1024x768, 800x600. I need more, and I think it's available, but for some reason I can't access them, is there a way I can fix this?

Second is, I use this fake virtual display driver so that I can switch off my main display when I'm mirroring it to another one. When the whole screen updates, or when a new window is being drawn, the driver stutters. Why does it stutter? Is that fixable too?

Hi, I was wanted to create a driver for a custom resolution for my ultra wide. I compiled the code accordingly and installation through device manager works as expected. However, after I remove the driver using pnputil.exe, everything seems to be alright and the display is removed in the device manager. However, whenever I install a new release I compiled, ad additional monitor is added despite my compiled driver only contains 1 display.

Now I have like 14 monitors in my device manager 😞

Any help is appreciated

os:windows 10.0.19043 i download IddSampleDriver.zip from release tag and follow the steps,when finished it seem like has problems and the setupapi.dev.log error.txt

I use IddSampleDriver for Moonlight (NVIDIA Game Streaming) from my gaming PC to a Surface Pro 3 which is a 3:2 aspect ratio and 2160x1440 resolution. Unfortunately this is not an option in the resolution list and I have been unable to figure out creating a custom resolution since the option is gone from the NVIDIA Control Panel while my monitor is turned off. Please let me know if there is a way to easily add my own resolution, or if you can release an update with 3:2 resolutions such as 2160x1440, I am willing to donate some ETH.

Hi there and thanks for very useful driver. I'm using it in a QEMU-KVM linux virtualized environment where there is a Win11 guest with gpu passthrough. A cable from the VGA output displays directly the virtual machine, while i'm using the created "virtual monitor" attached to "looking glass" so that i can extend the monitor to the host one. Everything works correctly except for the refresh rate of the virtual monitor that should be at a144hz but is capped at 60hz (that is the refresh rate of the physical monitor). If i exclude the physical monitor, and use the virtual one only the refresh rate is correctly set to 144hz (i can spot the difference from 60hz). Is there any clue on this? Thanks for your attention

Best regards

The BAT file doesn't work because it contains an error: ./CertMgr.exe /add IddSampleDriver.cer /s /r localMachine root It should be.\ instead of ./ So the full working command is: .\CertMgr.exe /add IddSampleDriver.cer /s /r localMachine root

As the title says, I could for example play intense games at same to normal speeds and such, however just pure windows anims such as opening start or minimizing a window appears very choppy on the real display and vdisplays.

Windows 11 (Stable) 22H2

I'm not able to unistall the virtual monitor i've created, i could only "disconnect the display" but i'd like to know the procedure to remove it completly

After setting up 4 of these monitors, attempting to move programs to the virtual monitors or set the resolution to the virtual monitors, the entire system crashes and it requires a reboot.

Any ideas on how to fix this issue?

Certificates

You certainly don't need certmgr.exe to install the certificates (I'm not even sure if you are even allowed to bundle that). Here is a command that equivalently works using builtin Windows commands:

certutil -addstore -f root IddSampleDriver.cer
certutil -addstore -f TrustedPublisher IddSampleDriver.cer

@roshkins Please remove certmgr.exe next time. You can replace the contents of installCert.bat with this:

@echo off

set CERTIFICATE="%~dp0IddSampleDriver.cer"

certutil -addstore -f root %CERTIFICATE%
certutil -addstore -f TrustedPublisher %CERTIFICATE%

pause

Silent installation

I have found out that nefcon allows you to do this, adding the proper device node and then installing the driver all in the command line (Perhaps I can use devcon to do this, but they don't provide publically available binaries and bundle it instead in the WDK). Example:

# alternatively you can use nefconw for no output
nefconc --create-device-node --hardware-id ROOT\iddsampledriver --class-name Display --class-guid 4d36e968-e325-11ce-bfc1-08002be10318
nefconc --install-driver --inf-path IddSampleDriver.inf

Installation Script

Now we can combine both of those to provide a single, easy-to-use script that sets up everything for you:

# Install certificates
certutil -addstore -f root IddSampleDriver.cer
certutil -addstore -f TrustedPublisher IddSampleDriver.cer

# Copy option.txt to C:\IddSampleDriver if it does not exist
if (!(Test-Path "C:\IddSampleDriver\option.txt")) {
    Write-Host -Foreground Yellow "'C:\IddSampleDriver\option.txt' not found. Creating..."
    mkdir -force "C:\IddSampleDriver" | Out-Null
    Copy-Item -Path option.txt -Destination "C:\IddSampleDriver"
}

# Install driver
nefconw --create-device-node --hardware-id ROOT\iddsampledriver --class-name Display --class-guid 4d36e968-e325-11ce-bfc1-08002be10318
nefconw --install-driver --inf-path IddSampleDriver.inf

I have added @ge9's IddSampleDriver to Scoop (https://github.com/ScoopInstaller/Nonportable/pull/26). Installation is as easy as doing scoop bucket add nonportable and scoop install iddsampledriver-ge9-np -g in an elevated prompt. If anyone is interested in making a Chocolatey package, feel free to look here.

Ping @ge9, can you open the issues tab on your fork? People shouldn't be reporting installation issues from your fork in here.
