What does Display Emulator / Dummy Plug do?
It fixes a problem you probably didn't even know you had - unlocking the full potential of your graphics card hardware. By simulating the presence of an attached display, display emulator allows you to use all of the power and available resolutions locked away inside your graphics hardware, which might otherwise be disabled when there is no screen available.

We have many choose, not only HDMI,but also DVI,VGA,DP,mini DP Dummy plug. Why do you need a HDMI/DVI/VGA Display Emulator?
HDMI/DVI/VGA Display emulator is a small, low-cost plug that work as a high resolution display, it makes a computer run "headless" (without a keyboard, mouse, and monitor).
It appears as a headless ghost display emulator (dummy plug) that fits discreetly in to the video output socket on your computer. Once plugged, the headless PC detects a connected display thus enabling the GPU.
Remote desktop access to the headless PC is then available at high resolution - up to 4096x2160 and high frame rate. With the GPU enabled, it is possible to perform for various tasks including high resolution hardware accelerated remote desktop and GPGPU operations like crypto currency mining, rendering and simulations.
It is a must-have for server and colocation farms, SOHO and home servers and remote-deployed headless PCs.


The HDMI Display Emulator is a small, low-cost DVI EDID Dummy Plug that emulates a high resolution display to make the computer run "headless" (without a keyboard, mouse, and monitor). By simulating the presence of an attached display, the emulator allows you to use all of the power and available resolutions locked away inside your graphics hardware, which might otherwise be disabled when there is no screen available.

Once the HDMI Dummy Plug is attached to the video output socket in your computer, your operating system will detect a connected display that enables the GPU external adapter. It appears as a headless ghost display in OS graphics card adapter plug properties window for easy identification. GPU hardware is often disabled until a display is attached resulting in poor performance and a limited working resolution for remote users. With the GPU enabled, it is possible to play games and stream as well as enjoy native high resolution remote desktop access for workstations, and provide stability to crypto currency mining rigs.
Works with PCs, Mac Mini, Intel NUC and any other device with HDMI output. HDMI 2.0, rx460, GTX1050 or above is required for 4K.
