HDMI 2.1 4K 120Hz EDID Emulator is engineered for next-generation GPUs and HDMI 2.1 devices that require stable 4K output and high refresh rate in headless or remote environments.

With a default virtual display of 3840×2160 @ 60Hz, it ensures reliable system startup and prevents common issues such as resolution fallback, GPU downclocking and black screens when no physical monitor is connected.

Unlike HDMI 2.0 dummy plugs limited to 4K 60Hz, this model advertises HDMI 2.1 EDID capabilities with up to 48Gbps bandwidth, enabling systems to activate 4K @ 120Hz display modes. This is essential for modern GPUs, game consoles and professional 4K workflows.

By emulating a full-featured 4K display, it keeps GPUs fully active and stable, making it ideal for GPU servers, cloud PCs, rendering workstations, KVM setups, game streaming and remote desktop access.

Default Resolution: 3840×2160 @ 60Hz
Maximum Supported Refresh Rate: Up to 120Hz (via HDMI 2.1 EDID emulation)

🚚✔ HDMI 2.1 EDID Emulator with 48Gbps Bandwidth Built on HDMI 2.1 EDID profiles, this dummy plug advertises up to 48Gbps link capability, enabling modern GPUs and consoles to unlock 4K @ 120Hz output modes that are not available with HDMI 2.0 adapters.
🚚✔ Default 4K Resolution for Reliable System Startup Provides a default virtual display of 3840×2160 @ 60Hz, ensuring stable graphics initialization, preventing resolution fallback and eliminating black screens in headless or remote setups.
🚚✔ Unlocks 4K @ 120Hz on Systems Supports 4K 120Hz EDID emulation, allowing GPUs (RTX 30/40, RX 6000/7000) and consoles (PS5, Xbox Series X) to enable high-refresh 4K modes. (Actual output depends on GPU, cable and system .)
🚚✔ Designed for Headless GPUs & High-End Workflows Keeps GPUs fully active by emulating a real 4K display—ideal for GPU servers, rendering nodes, KVM systems, game streaming, VR pipelines and remote desktop environments.
🚚✔ Wide Resolution & Refresh Rate Compatibility Supports a broad resolution set from 3840×2160 down to 800×600, with multiple refresh rates up to 120Hz, ensuring compatibility with both modern and legacy systems.
