Say Goodbye to Remote Desktop Lag and Black Screens! The MOUNiUBULL 4K HDMI Dummy Plug (3 Pack) is the ultimate solution for anyone using AnyDesk, TeamViewer, or Windows Remote Desktop to access PCs, servers, or Mac Minis remotely without a connected monitor.
Why Do You Need This Adapter? When you control a PC remotely without a screen plugged in, your system often drops to a tiny 640x480 resolution, causing laggy performance and black screens. This HDMI Dummy Plug tricks your PC into thinking a 4K monitor is connected, unlocking your Graphics Card's full power and rendering smooth, high-definition visuals.
Key Advantages:
Crisp 4K Resolution: Enjoy up to 3840x2160@60Hz & 1080P@120Hz remote display quality.
GPU Hardware Acceleration: Prevents your graphics card from going into low-power sleep mode.
Driver-Free Setup: Instant plug-and-play compatibility across Windows 11/10/7, Linux, and macOS.
Compact Gold-Plated Design: Fits seamlessly into server racks and multi-GPU setups without blocking adjacent ports.
(Package Includes: 3 x MOUNiUBULL 4K HDMI Dummy Plugs)
