What do you do when you want to tinker with GPU hardware, but you don't have a display on hand?
This HDMI Dummy Plug is a small device that acts as a display emulator. Once it's plugged into the video output socket on your device or computer, the plug punks the operating system into detecting a connected display, and voilà! Now you have unimpeded access to your graphics card hardware.
The plug only contains the I2C EDID EEPROM. Plug and play and can simulate up to 4K resolution (3840 x 2160) HDMI displays.

Plain-language definitions for the technical terms used above.
- EEPROM
- A type of non-volatile memory that keeps stored data even when power is turned off. In a sensor module, it can be used to store settings or calibration data so they do not need to be re-entered every time.
- HDMI
- HDMI is a common digital video and audio connection used by computers, media players, and many displays. If a display kit has HDMI input, it is usually much easier to test with a single-board computer because it can act like a normal monitor.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
