Test method and test device for MHL port

The invention discloses a test method and a test device for an MHL port. The method comprises the following steps: establishing connection with the MHL port of a television to be tested; and acquiringthe voltage of each pin of the MHL port of the television to be tested, and testing the MHL port according to the voltage of each pin and the EDID acquisition operation executed on the television tobe tested. The technical problems that an existing method for testing the television MHL function is high in testing cost and low in testing efficiency are solved. 本发明公开了一种MHL端口的测试方法及测试装置，方法包括：与待测电视的MHL端口建立连接；获取所述待测电视的MHL端口的各引脚的电压，并根据各引脚的电压以及向所述待测电视执行的EDID获取操作对MHL端口进行测试。本发明解决了测试电视MHL功能的现有方法测试成本大和测试效率低的技术问题。
