    Is a DVI-D and a display port the same thing?

    I have a T420 and apparently I need a display port to HDMI cable to connect it with my TV. I have a DVI-D to HDMI cable, is that the same thing?

    If the connector does not fit on both ends then it's not the same...plain and simple.

    ...? So you need a DisplayPort to XX adapter, but you have an DVI to HDMI cable?

    You can do DisplayPort to DVI.

    Don't listen to Nemix.

    HDMI, DVI, and DisplayPort are each separate things, but your DVI-D to HDMI cable will work just fine for video if your laptop has an HDMI port. If it only has a displayport you might need an adapter.

    DVI is capable of sending analog (VGA) and digital signals in the same connector. HDMI uses the same digital interface, and is pin-compatible with DVI connectors that use the digital channels.

    No apparently my laptop has a display port.
    I need a display port to HDMI cable.
    I accidently bought a DVI to HDMI.

    I realize now though, DVI and display port are two different things and I bought the wrong thing.

    LOL...jokes on you dtd00d.

    Anyhow, technically Display Port > HDMI > DVI-D.

    HDMI and DVI-D are interchangeable but both cannot output to Display Port.

    However, Display Port can output to the lower grade video signals.

    since when can DVI-D carry audio?

    doesn't DVI-D also have a resolution advantage over HDMI?

    at OP: yes, dvi is SIGNIFICANTLY larger than display port :p

    Many, if not most, DVI ports can output sound if used with a DVI-HDMI adapter.
    Depends, but yes, dual-link DVI has more throughput than HDMI, which is limited to a single link.

    Er, I think DVI is limited to dual link digital video and an analog video channel. You'd need special equipment to know that the analog channels were carrying audio instead of video or something. Passive DVI to HDMI adapters can only translate video.

    When hooked up with a DVI to HDMI adapter, many DVI ports can output the full HDMI signal, including digital audio.

    OP said DVI-D. No Analoug. That's reserved for DVI-I and DVI-A.

    For whomever cares, DP supports Deep Color, along with HDMI. DVI (even in it's DL flavor) doesn't.
