Xieoery HDMI EDID Emulator 4K 120Hz, HDMI Dummy Plug with YCbCr 4:2:0 Support, Default 3840×2160@60-120Hz Virtual Display for Headless PCs, GPU Servers & Remote Desktop

🚚⃣ 4K 120Hz EDID Emulation with YCbCr 4:2:0

Designed to advertise 4K @ 120Hz display capability using YCbCr 4:2:0 chroma format, enabling high-refresh 4K output on compatible GPUs and systems where RGB bandwidth is limited.

🚚⃣ Stable Default 4K Initialization

Provides a default virtual display of 3840×2160 @ 60Hz, ensuring reliable system startup and preventing resolution fallback, display detection errors or black screens in headless environments.

🚚⃣ Optimized for Bandwidth-Efficient 4K Output

YCbCr 4:2:0 reduces signal bandwidth while maintaining full 4K resolution, making it ideal for HDMI-based systems, long cable runs, KVM setups and remote desktop workflows that require stability over raw bandwidth.

🚚⃣ Keeps GPUs Fully Active Without a Monitor

By emulating a connected 4K display, this EDID emulator prevents GPU downclocking, idle states and forced low-resolution modes, ensuring consistent graphics performance for servers and workstations.

🚚⃣ Built for Professional & Headless Use Cases

Perfect for GPU servers, cloud PCs, virtualization platforms, media processing, remote access and testing environments where accurate display negotiation is required without a physical monitor.
