That means you have the standard 5-pin connector. It is not
an 11-pin connector. You will need a 5-pin to 11-pin adapter if you want to have the Note 3 mirror the screen.
Here's an image of what the heads look like. As you can see they are different.
And for those wondering why: this 11-pin configuration allows both USB OTG and
MHL to work together simultaneously (ie. Samsung Smartdock). The 5-pin only allows you to connect MHL or
USB OTG only. They cannot be used simultaneously together. I find this a much added benefit as I can use it as a mini backup system (keyboard, mouse, USB hub, external HDDs, flash drives, etc with output to a monitor).
The drawback is that the 2A charger is not sufficient to charge the Note 2 (powering the MHL connection/USB though Smartdock). Even with a powered USB hub connected, the Note 2 will still lose charge when connected. Albeit not a huge drain, but it will still drain the battery good.
