Thank you for viewing. This is a BENFEI DisplayPort adapter. It supports resolutions up to 4K@30Hz. *This is not a bi-directional converter, so it cannot transmit signals from HDMI to DisplayPort. I have used it for about a year. It works without any problems and there are no major scratches, but please refrain from purchasing if you are sensitive to used items. I am also selling other related equipment. I can offer a small discount if you purchase multiple items, so please let me know in the comments section. If there are no issues, please proceed with the purchase. PC/Monitor/Projector
