what is this?1. HDMI dummy plug is a display emulator (virtual plug), after connecting Headless Ghost, your operating system will detect a virtual display and enable GPU, and this virtual display has the same function as real display.2. GPU hardware is often disabled until a monitor is connected, resulting in poor performance and limited resolution for remote users to work on.3. When the GPU is enabled, various tasks can be performed, including high resolution and refresh rate enabling hardware to accelerate GPGPU operations such as remote desktop and cryptocurrency mining, and the resolution supports 800x600@[email protected] can it help you?1.
