## Description

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.
