    I'm buying a monitor today that comes with a VGA cable only but the monitor also has a DVI port. How do I go about doing the following:

    VGA > HDMI > Mini Display Port

    Or

    DVI > HDMI > Mini Display Port

    Thanks.

    ----------

    I'm thinking:

    DVI cable plugged into the screen plugged into a DVI to HDMI splitter and then a HDMI to Minidisplay port plugged into the other side of that. Will this work?

    What about using a simple Mini DisplayPort (MDP) to DVI adapter plus DVI cable?
    Using a MDP to HDMI adapter and then a VGA cable will not work, as MDP and HDMI are digital and VGA is analog, and AFAIK HDMI is digital only.

    Only the MDP - HDMI - DVI convolution might work.

    The best picture will be gotten using only one adapter instead of two, thus I recommend going either the MDP > VGA > VGA cable, MDP > DVI > DVI cable or MDP > HDMI > HDMI cable route (if the monitor supports HDMI input).
    Do not mix them.
    The best is MDP to DVI, unless you want to watch copy protected movies and need HDCP, thus you should use HDMI, but then again, if you use HDMI and "convert" it to DVI again (if the monitor has no HDMI input), HDCP will not work.

    In short, go the MDP > DVI route if HDCP is not of concern and you are interested in the best picture quality.

    See thats the thing, it doesn't have an HDMI port. Will DVI > MDP work better than DVI > HDMI > MDP

    Why do you want to use HDMI? And yes, MDP > DVI will work better, one less variable to troubleshoot if MDP > HDMI > DVI does not work.

    You can get MDP > DVI adapters and DVI cables (if the monitor does not come with one, which would be strange) go to MonoPrice (as linked to in the MDP quote) for adapters and cables for less than 10 USD each, if you are residing in North America.

    Does MDP = Thunderbolt?

    My 2012 comes with Thunderbolt, so if I buy a MDP to HDMI, it will work?

    As seen in the quote in post #2, Thunderbolt is backwards compatible to MDP.

    To learn more about Thunderbolt (TB) and its compatibility with Mini DisplayPort (MDP):

    I wanted to use HDMI because I thought it would result in better picture quality. But if it doesn't I'll just get the DVI MDP

    ----------

    So I should get a DVI to TB instead of DVI to MDP, that would work better?

    Which would give the better picture quality? DVI to MDP or DVI to TB?

    As noted in post #8, TB is backwards compatible.
    There are also no TB > DVI adapters, as you can use MDP > DVI adapters.
