The HDMI Display Emulator is a small, low-cost Dummy Plug that emulates a high resolution display to make the computer run "headless" (without a keyboard, mouse, and monitor).
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.
