Frequently Asked Questions

Q: What is a dummy plug virtual display adapter and why do I need one?

A: A dummy plug (also called a headless ghost display emulator) is a small adapter that plugs into your GPU's HDMI, DVI, or VGA port and simulates a real monitor being connected. This is essential for headless PCs, remote desktop setups, mining rigs, and GPU compute servers where no physical monitor is present — keeping your graphics card fully active and allowing you to set high custom resolutions remotely.

Q: Does the HDMI dummy plug really support 4K resolution?

A: Yes! The HDMI version supports resolutions up to 3840 × 2160 (4K) @ 60Hz and 1080P @ 120Hz, provided your graphics card has an HDMI 2.0 compatible port. VGA and DVI versions support up to 1920 × 1080 @ 60Hz.

Q: Is this adapter compatible with my operating system?

A: Absolutely. The virtual display adapter is fully plug-and-play with no drivers required, making it compatible with all major operating systems including Windows, macOS, and Linux.

Q: Can I use this on a mining rig to prevent GPU shutdowns?

A: Yes. One of the primary use cases for this dummy plug is stabilizing GPU behavior on mining rigs. By simulating an attached display, it prevents the graphics card from powering down or malfunctioning due to the absence of a real monitor.
