Product Definition: This product is a graphics card spoofer that simulates the EDID information of a physical monitor, tricking the operating system and graphics driver into identifying it as a "connected" display device. Technical Use: When the host computer is running without a real monitor (headless mode), it ensures that the graphics card outputs images at full capacity, avoiding performance throttling, black screens on the remote desktop, or unexpected application exits. Typical Application Scenarios: Game Studios: Allow multiple game clients to run on the fly, saving display equipment costs and space. Data Centers/Servers: Remotely manage graphics card servers (such as render farms and AI computing) without connecting to a monitor. Software Testing: Automated testing of software performance at different resolutions. Home Users: Use a desktop computer as a remote server while maintaining graphics card performance. Instructions: Plug directly into an available video output port on the graphics card (DP or native HDMI is recommended). After the system boots up, the virtual display will be recognized in the display settings and the resolution can be set.
