When you think of a display that connects to its source over HDMI, you probably think of the TV in your living room, your desktop monitor, or maybe even a smaller display, like a portable monitor. You probably don't think of an OLED PC monitor that measures 0.96 of an inch diagonally.

While acknowledging the limited uses for a tiny HDMI PC monitor, maker mitxela had the urge to get a 128×68 dot matrix OLED screen up and running as a PC monitor that connects directly to its system. The maker described the creation as the "smallest and worst HDMI display ever."

A small OLED screen isn't special on its own. Makers use them for all sorts of projects, like DIY smartwatches, message boards, or weather displays, for example. What makes mitxela's project unique is that it turns the OLED panel into a standard PC monitor that can be plugged into the PC's HDMI port directly—no Arduino or microcontroller required.
