Do you have Optimus?

Is the graphics driver properly installed?

Re: T520 Display Port Not Working in Windows or Ubuntu

Hi,

 

I have a  brand new September 2011 T520. My display port works perfectly for AUDIO and VIDEO. It is very important that you get the right adapter. I bought the StarTech DisplayPort to HDMI Video AND Audio Adapter Converter. I was worried by all the negative posts about lenovo displayports, But now that I have tested it and it works fine. Make sure your adapter says AUDIO AND VIDEO and you Run the update tool in the lenovo tool box. (Blue ThinkVantage Button.)

Anyways if you have the right adapter it was super easy. All you have to do is connect it up and your good to go!
