        <pre wrap="">    Not sure about the hardware in the thinkpad. I would think that it
    would have a dual purpose displayport / hdmi port, but if it
    doesn't, you can get an active displayport to hdmi, would be cheaper
    than another laptop. &lt;br&gt;

Hmmm... I'll study that a bit. But I assume that in my T520. there is no
physical connection of the DisplayPort to anything...</pre>

    There is no sense in that. It has to be connected to something, if
    you have intel only then it is connected to the Intel. I had the
    w520 with NVIDIA at the time, and it was more messed up as it was
    stilled connected to the Intel, but the xserver went crazy when I
    connected a cable and would only work when the bios was set to
    discrete graphics.<br>
    <br>
    The question is more whether the hardware will output both
    displayport and hdmi signals (which are different) which would allow
    using a passive displayport to hdmi cable, or whether hardware is
    displayport only, which would require an active cable (less likely,
    more common in discrete desktop graphic cards).<br>
    <br>
    My guess is that either the adapter is faulty or you need to trigger
    external display detection, as opposed to the port not being
    connected to anything or a displayport only port.<br>

ThinkWiki says:

"The T520 also requires Discrete Graphics to use DisplayPort. "
