NewerTech Headless Video

NewerTech NWTADP4KHEAD is an HDMI headless display emulator for enabling a computer’s GPU when accessing the system remotely. It plugs into an available HDMI port and provides an emulated display without requiring driver installation or configuration.

The adapter supports resolutions up to 4096 × 2160. Actual available modes depend on the computer and operating system. The listing identifies support for macOS, Windows and Linux, making the device suitable for remote-access setups across these platforms.

Its compact body measures 2.5 × 1.8 × 0.6 cm and weighs 6 g, so it occupies little space at the HDMI connection.
