HDMI EDID Emulator 4K UHD, HDMI Dummy Plug with YCbCr 4:2:0 Support, Default 3840×2160@60Hz Virtual Display for Stable 4K HDMI Output in Headless Systems

About this item

• 🚚 Stable 4K UHD EDID Emulation Advertises a 4K UHD (3840×2160) virtual display, allowing systems to correctly negotiate 4K output even when no physical monitor is connected.
• 🚚Default 3840×2160 @ 60Hz Initialization Provides a reliable default 4K @ 60Hz display mode, ensuring consistent startup behavior and preventing resolution fallback or display detection errors.
• 🚚YCbCr 4:2:0 for Reliable HDMI Compatibility Supports YCbCr 4:2:0 color format via EDID, reducing bandwidth requirements while maintaining full 4K resolution—ideal for HDMI-based systems where RGB 4:4:4 is unstable or unsupported.
• 🚚Keeps GPUs Active in Headless Environments By emulating a connected 4K display, this EDID emulator prevents GPU idle states, forced low-resolution modes and black screens, ensuring smooth remote access and system operation.
• 🚚 Designed for Professional & Infrastructure Use Perfect for servers, remote desktops, KVM switches, industrial PCs, media systems and testing environments where stability and compatibility matter more than extreme refresh rates.
