The invention relates to the field of DVI plugs, and specifically relates to an easy-to-distinguish DVI plug. The easy-to-distinguish DVI plug comprises a plug body. A spindle is mounted inside the plug body along the plugging direction. Two identification disks are connected in series and side by side on the spindle. The periphery of each identification disk is provided with a plurality of scales distributed evenly. Arrows facing towards the identification disks respectively are oppositely arranged at one side of the plug body outside the two identification disks. According to the easy-to-distinguish DVI plug, the identification disks facilitate distinguishing, the work efficiency of workers is improved, the problem that a DVI line is easy to confuse is solved, and the structure is convenient and helpful to improve the work efficiency. Moreover, the DVI plug can be disassembled with the help of the identification plates, and is easy to pull out.
