Datasheet

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 fools the operating system into detecting a
connected display, and then 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.
 Dimensions: 26 x 20 x 8.2mm
