• ? Default 2K Resolution for Stable Startup Provides a default 2560×1440 @ 60Hz virtual display on boot, preventing resolution fallback, black screens and GPU idle states when no physical monitor is connected.
• ? Supports High Refresh Rates up to 144Hz Advanced EDID profiles support 2K and Full HD resolutions from 60Hz up to 144Hz, delivering smoother visuals for remote desktop, KVM switching and high-refresh desktop environments. (Actual refresh rate depends on GPU and system support.)
• ? HDR-Capable EDID Emulation Includes HDR metadata in EDID, allowing compatible GPUs and operating systems to enable HDR output modes in headless setups. Helps maintain correct color behavior and tone mapping without a real display.
• ? Keeps GPU Fully Active in Headless Mode Acts as a virtual monitor to prevent GPU downclocking, resolution limits and display detection errors, ensuring consistent graphics performance for servers, virtual machines and rendering nodes.
• ? Wide Compatibility for Professional Systems Works with Windows, Linux and macOS, and is ideal for GPU servers, cloud PCs, virtual desktops, rendering workstations, mini PCs and industrial systems.
