DTech DTECH HDMI Dummy Plug 4K Display Emulator Compatible with Windows Mac OSX Linux (fit-Headless, 3 pack)

After setting up my first mini PC with an Intel iGPU as a headless server, I ran into what is apparently a common issue: the PC would not boot into the GUI without a connected monitor. In addition to that, the Intel video driver would not load properly, meaning I couldn't use the GPU for Plex hardware transcoding. And finally, I couldn't RDP/VNC into the machine. It seems like this little dummy plug fixed all of my issues. Linux recognized it as a connected monitor, and now the machine boots properly, the Intel video driver loads as expected and I can remotely connect to the PC. An interesting solution to an interesting problem.

Perfect for what I needed, which was to act as a display emulator plug on a server, for the HDMI port. Decent quality and worked as expected.

all good

DTECH HDMI Dummy Plug 4K Display Emulator works well. I use one on a headless server with very old and flaky on-board video that doesn't output anything unless a monitor is attached before booting. Using the HDMI dummy plug allows me to boot the server without a monitor attached, and attach a monitor later if needed.
