+#Scripts
+
+This is a collection of Powershell scripts, written during the whole driver development. There haven't been a focus on keeping the scripts "up to date" all the time. Which means changes that might have occurred in the modules that these scripts depend upon, haven't been corrected either. 
+
+This is more ment as a framework for "tinkers" to make use of Powershell to change settings on the fly. 
+
+To use these, you should be at least be comfortable with Powershell and understand Admin privilegiets, risk/reward.
+
+PR's are welcome for improvements or other/more functions.

-### THIS SAMPLE IS INCOMPLETE - Currently a Work in Progress attempt at HDR and 10-bit video support.
-
----
-page_type: sample
-description: "Implements most DDIs that a display-only miniport driver should provide to the Windows Display Driver Model (WDDM)."
-languages:
-- cpp
-products:
-- windows
-- windows-wdk
----
-
-# Kernel mode display-only miniport driver (KMDOD) sample
-
-The kernel mode display-only miniport driver (KMDOD) sample implements most of the device driver interfaces (DDIs) that a display-only miniport driver should provide to the Windows Display Driver Model (WDDM). The code is useful to understand how to write a miniport driver for a display-only device, or how to develop a full WDDM driver.
-
-For more info on WDDM drivers, see [Windows Display Driver Model (WDDM) Design Guide](https://docs.microsoft.com/windows-hardware/drivers/display/windows-vista-display-driver-model-design-guide).
-
-This code can also help you to understand the use and implementation of display-related DDIs. The INF file shows how to make a display miniport driver visible to other WDDM components.
-
-The sample can be installed on top of a VESA-capable graphics adapter, or on top of a graphics device that supports access to frame buffer memory through the Unified Extensible Firmware Interface (UEFI).
-
-The sample driver does not support the *sleep* power state. If it is placed in the sleep state, the driver will cause a system bugcheck to occur. There is no workaround available, by design.
-
-If the current display driver is not a WDDM 1.2 compliant driver, the sample driver might fail to install, with error code 43 displayed. The KMDOD driver is actually installed, but it cannot be started. The workaround for this issue is to switch to the Microsoft Basic Display Adapter Driver before installing the KMDOD sample driver, or simply to reboot your system after installing the KMDOD sample.
-
-## Installation
-
-In Microsoft Visual Studio, press **F5** to build the sample and then deploy it to a target machine. For more info, see [Deploying a Driver to a Test Computer](https://docs.microsoft.com/windows-hardware/drivers/develop/deploying-a-driver-to-a-test-computer).
-
-In some cases you might need to install the driver manually, as follows.
-
-1. Add the following files to the directory given by ...\\[x64]\\C++\\Package:
-
-    - SampleDriver.cat
-
-    - SampleDriver.inf
-
-    - SampleDriver.sys
-
-    - SampleDriver.cer
-
-1. Unless you've provided a production certificate, you should manually install the SampleDriver.cer digital certificate with the following command:
-
-    `Certutil.exe -addstore root SampleDriver.cer`
-
-1. Then enable test signing by running the following BCDEdit command:
-
-    `Bcdedit.exe -set TESTSIGNING ON`
-
-    > [!NOTE]
-    > After you change the TESTSIGNING boot configuration option, restart the computer for the change to take effect.
-
-    For more info, see [The TESTSIGNING Boot Configuration Option](https://docs.microsoft.com/windows-hardware/drivers/install/the-testsigning-boot-configuration-option).
-
-1. Manually install the driver using Device Manager, which is available from Control Panel.
-
-### ACPI-based GPUs
-
-To install the KMDOD sample driver on a GPU that is an Advanced Configuration and Power Interface (ACPI) device, add these lines to the `[MS]`, `[MS.NTamd64]`, and `[MS.NTarm]` sections of the Sampledisplay.inf file:
-
-```inf
-Text
-" Kernel mode display only sample driver " = KDODSamp_Inst, ACPI\CLS_0003&SUBCLS_0000
-" Kernel mode display only sample driver " = KDODSamp_Inst, ACPI\CLS_0003&SUBCLS_0001
-" Kernel mode display only sample driver " = KDODSamp_Inst, ACPI\CLS_0003&SUBCLS_0003
-```
-
-This new code provides generic identifiers for ACPI hardware.
-
-You can optionally delete the original lines of code within these sections of the INF file.

-# Virtual Display Driver
-based on Microsoft Indirect Display Driver Sample. This creates a virtual display in Windows that acts and functions just like a real one. It's useful for streaming, virtual reality applications, recording, headless servers, etc. The benefit over a physical display is the ability to adjust resolutions and refresh rates beyond the physical displays capabilities. For example, this would enable the ability to stream a game from your home PC using game streaming software at 240hz at 8K while owning a 60hz 1080p monitor (unrealistic, but explains the abilities well). For servers without displays, this enabled remote desktop and screen streaming to other systems as if there were a display installed.

+This project creates a _virtual monitor_ in Windows that functions just like a physical display. It is particularly useful for applications such as **streaming, virtual reality, screen recording,** and **headless servers—systems** that operate without a physical display attached. 
 
-## Download
+Unlike traditional monitors, this virtual display supports custom resolutions and refresh rates beyond hardware limitations—offering greater flexibility for advanced setups. You can also use custom EDIDs to simulate or emulate existing hardware displays.
 
-- [Windows 10 and 11 (no HDR)](https://github.com/itsmikethetech/Virtual-Display-Driver/releases/tag/23.10.20.2)

- 
-## Installation
+## ⬇️ Download Latest Version
 
-1. Download the latest version from the releases page, and extract the contents to a folder.
-2. Copy `option.txt` to `C:\IddSampleDriver\option.txt` before installing the driver **(important!)**.
-3. Right click and run the *.bat file **as an Administrator** to add the driver certificate as a trusted root certificate.
-4. Don't install the inf. Open device manager, click on any device, then click on the "Action" menu and click "Add Legacy Hardware".
-5. Select "Add hardware from a list (Advanced)" and then select Display adapters
-6. Click "Have Disk..." and click the "Browse..." button. Navigate to the extracted files and select the inf file.
-7. You are done! Go to display settings to customize the resolution of the additional displays. These displays show up in Sunshine, your Oculus or VR settings, and should be able to be streamed from.
-8. You can enable/disable the display adapter to toggle the monitors.
+- [Driver Installer (Windows 10/11)](https://github.com/VirtualDisplay/Virtual-Display-Driver/releases) - Check the [Releases](https://github.com/VirtualDisplay/Virtual-Display-Driver/releases) page for the latest version and release notes.
 
-Ps. Make sure that options.txt is accesible for the system at `C:\IddSampleDriver\option.txt` or the installation will fail.
+> [!IMPORTANT]
+> Before using the Virtual Display Driver, ensure the following dependencies are installed:
+> - **Microsoft Visual C++ Redistributable**  
+>   If you encounter the error `vcruntime140.dll not found`, download and install the latest version from the [Microsoft Visual C++ Redistributable page](https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170).
 
-## Uninstalling
+## 🖥️ EDID Database
+- [EDID Database by Bud3699](https://edid.mikethetech.com/)
 
-1. Open device manager
-2. Locate Display Adapters
-3. Right click on IddSampleDriver, choose "Uninstall device"
-4. There is a new popup window, in there click Attempt to remove driver for this device.
+  You can use this database to load custom edid's into the driver! Or just general edid usage :) 
 
-Next instructions are for those cases where the device is removed from the system, but driver stil remains. This happens when there is a connection to the device while trying to remove the drivers. To
-remedy this, there is a a few tricks built into windows. So here goes:
+## 🛠️ Installation
 
-5. Open up a powershell terminal and input this:
-6.  ```pnputil /enum-drivers```
-6. Locate iddsampledriver.inf, there might be multiple pages of text. Make a note of the "published name", it's often unique for your system, but might look like "oem139.inf"
-7.  ```pnputil /delete-driver oem139.inf```
+- Step 1: Download the Installer
+   - You can download the installer directly from the [Releases](https://github.com/VirtualDisplay/Virtual-Display-Driver/releases) page.
 
-## HDR Support Now Available for Windows 11 22H2+ 
+- Step 2: Run the Installer
+   - Launch the installer.
+   - Follow the on-screen instructions to complete the installation.
 
-### Resolutions:
+- Step 3: Verify the Installation (Optional)
+   - Check if the Virtual Display Driver is correctly installed by running the following:
+   - **Device Manager:** Check "Device Manager" under "Display Adapters."
+   - **Settings:** Check display settings under system settings and see if the virtual displays show.

-## Background reading ##
+## Developers
 
-Start at the [Indirect Display Driver Model Overview](https://msdn.microsoft.com/en-us/library/windows/hardware/mt761968(v=vs.85).aspx) on MSDN.
-
-### Code structure ###
-
-The sample driver code is very simplistic and does nothing more than enumerate a single monitor when its device enters the D0/started power state. The IDD runs in Session 0 without any components running in the user session, so any driver instability will not affect the stability of the system as a whole. The IDD is a user-mode only model with no support for kernel-mode components. As such, the driver is able to use any DirectX APIs in order to process the desktop image. In fact, the IddCx provides the desktop image to encode in a DirectX surface.
-
-* `Direct3DDevice` class
-    * Contains logic for enumerating the correct render GPU from DXGI and creating a D3D device.
-    * Manages the lifetime of a DXGI factory and a D3D device created for the render GPU the system is using to render frames for your indirect display device's swap-chain.
-* `SwapChainProcessor` class
-    * Processes frames for a swap-chain assigned to the monitor object on a dedicated thread.
-    * The sample code does nothing with the frames, but demonstrates a correct processing loop with error handling and notifying the OS of frame completion.
-* `IndirectDeviceContext` class
-    * Processes device callbacks from IddCx.
-    * Manages the creation and arrival of the sample monitor.
-    * Handles swap-chain arrival and departure by creating a `Direct3DDevice` and handing it off to a `SwapChainProcessor`.
