Q. Is every HDMI adapter the same?

Answer

No there are three different sizes of HDMI connectors: normal mini and micro. In addition HDMI cables come in a variety of varieties. Even if a cable doesn't have the logo it should state whether it's a standard high-speed premium-speed or ultra-high-speed cable in the product description. Common HDMI cables are all the same. The specifications of the ports on the gadgets are the most important consideration. While there are several varieties of HDMI the vast majority of cables should work for the typical consumer's needs. However there are a few exceptions that are worth investigating.
