WindowsDisplayAPI

This is a modified fork of the original WindowsDisplayAPI library maintained for the Lenovo Legion Toolkit project.

NuGet Version NuGet Downloads License Commit Activity Issues

WindowsDisplayAPI is a lightweight .NET wrapper for the Windows Display and Connecting and Configuring Displays (CCD) APIs. It enables developers to query, configure, and manage display topologies, resolutions, refresh rates, and scaling settings programmatically.

Installation

The library is available on NuGet. You can install it using the NuGet Package Manager Console:

dotnet add package LLT.WindowsDisplayAPI

For more details, visit the LLT.WindowsDisplayAPI NuGet Page.

Features & Windows API Support

Feature / Interface Subsystem / Flag Status Description
Display Topologies & Modes CCD (Clone, Extend, Internal, External) Supported Full topology querying, path switching, and validation.
Resolution & Refresh Rates CCD (Standard) Supported Custom resolutions, progressive/interlaced refresh rate rationales.
Dynamic Refresh Rate (DRR) CCD (BoostRefreshRate, VirtualRefreshRateAware) Supported Full support for Windows 11 Dynamic Refresh Rate boost paths.
DPI Scaling CCD (GetSourceDPIScale, SetSourceDPIScale) Supported Per-source DPI scale percentage reading and modification.
Virtual Resolution CCD (Get/SetSupportVirtualResolution) Supported Virtual mode and virtual resolution configuration.
HDR / Advanced Color Info CCD (GET_ADVANCED_COLOR_INFO = 9) In Progress (In LLT) Query HDR and Wide Color Gamut (WCG) capability and active state.
HDR State Control CCD (SET_ADVANCED_COLOR_STATE = 10/14) In Progress (In LLT) Programmatically toggle HDR on/off per display.
SDR White Level in HDR CCD (GET_SDR_WHITE_LEVEL = 11) Planned Read SDR content brightness slider value (nits) in HDR mode.
Monitor Specialization CCD (GET/SET_MONITOR_SPECIALIZATION = 12/13) Planned Check or configure specialized displays (HMD / VR / Medical panels).
Advanced Color Primaries CCD (GET_ADVANCED_COLOR_INFO_2 = 15) Planned Retrieve color gamut chromaticity coordinates and peak luminance.
DDC/CI Hardware Controls DXVA2 (dxva2.dll) Planned External monitor hardware brightness, contrast, and VCP inputs.
DXGI Hardware Color Metrics DXGI (DXGI_OUTPUT_DESC1) Planned Real panel peak luminance (nits), bit depth, and color space gamut.
Windows Color Management WCS / ICM (mscms.dll) Planned Query and assign ICC/ICM color profiles per display.
