Xieoery HDR HDMI Dummy Plug 4K 120Hz, EDID Emulator for Headless PCs, GPU Servers, Remote Desktop, Cloud Rendering, Virtual Monitor Adapter (Recommended 3840×2160 60Hz HDR)

🚚 Optimized 4K HDR EDID with Recommended 3840×2160 60Hz

Engineered around a 4K HDR default profile of 3840×2160@60Hz, ensuring highly accurate color, brightness and tone-mapping behavior. Ideal for high-end GPUs, rendering workflows and remote desktops needing stable UHD output.

🚚 Full HDR Metadata Support: PQ EOTF, BT.2020, Deep Color

Includes HDR10-level metadata such as PQ gamma, wide-gamut BT.2020 indicators and deep-color signaling. Allows GPUs to activate real HDR output—even without an actual display—delivering richer detail and dynamic contrast.

🚚 Headless Ghost Mode Prevents Resolution & GPU Errors

Simulates a full-function HDR monitor. Eliminates black screens, incorrect scaling, GPU downclocking and remote desktop resolution limits. Reliable for headless servers, virtualization hosts and cloud rendering systems.

🚚 High Refresh Rate Capability up to 120Hz Across Multiple Modes

Supports 23/24/25/29/30/50/59/60/119/120Hz depending on resolution. Ideal for streaming, testing, KVM switching and multi-monitor emulation.

🚚 Expanded EDID Library Ensures Compatibility with Any GPU

Covers a wide range of display formats—from 4K down to legacy modes—ensuring stable detection on modern workstations, mini PCs, industrial computers and older graphics hardware.
