To close the loop: HDMI: https://www.amazon.com/Headless-Display-Emulator-Headless-1920x1080-Generation/dp/B06XT1Z9TF ($7 US) VGA: https://www.amazon.com/Headless-Display-Emulator-Headless-1920x1080-3Pack/dp/B071RR811W ($16 for a three pack) DisplayPort: https://www.amazon.com/FUERAN-Emulator-Headless-3840x2160-HDMI-Compatible-Ethereum/dp/B06XSZR7CG/ ($6 US) I am not recommending Amazon as a vendor or these particular devices, simply illustrating that they exist and are reasonably priced. -dsr-
