This is the ELECOM DisplayPort to HDMI conversion cable (1.0m) in black, model CAC-DPHDMI10BK. It's a conversion cable that converts the video signal from a computer with a DisplayPort terminal and outputs it to a display, etc., with an HDMI input terminal. I threw away the box when I opened it. I bought it for a new display, but the shape was wrong and it didn't fit, so I haven't used it even once. I was able to confirm the purchase history, so I'm listing it for sale. I purchased it in mid-November 2025.
