$3 HDMI dummy plug resolves headless server GPU issues

xda-developers.com

A $3 HDMI dummy plug can resolve issues with headless servers not booting or having disabled GPU features. These small adapters mimic a connected monitor's EDID data, tricking the GPU into believing a display is present, enabling full functionality and preventing low-power modes or hardware acceleration disabling. The inexpensive solution is particularly useful for home labs and multi-GPU setups, though users should ensure the dummy plug supports desired resolutions.
