• ? 12-Bit Deep Color HDR EDID Emulation Emulates HDR-capable EDID with 12-bit deep color support, allowing compatible GPUs and operating systems to enable higher color depth modes for smoother gradients and reduced banding in HDR workflows.
• ?HDR Metadata with 409 Nits Peak Brightness Includes HDR EDID metadata with a declared peak brightness of 409 nits, enabling proper HDR tone mapping behavior in headless environments without a physical display.
• ?Default 4K Resolution for Stable Initialization Provides a default virtual display of 3840×2160 @ 60Hz, ensuring reliable graphics initialization and preventing resolution fallback, GPU downclocking or black screens.
• ?Designed for Color-Critical Headless Workflows Ideal for HDR video pipelines, color-critical remote desktops, rendering nodes and GPU servers that require accurate color depth and HDR behavior without a connected monitor.
• ? Plug & Play Wide Compatibility Works with Windows, Linux and macOS, supporting a wide range of common resolutions and refresh rates for modern and legacy systems.
