What port is this?

Question

Questions:

1. Is the display plug in the following picture indeed a Mini-DVI?

2. Would this cable work? (I would use a regular DVI Male to Male with it)?

Why? My friend wants to connect her Mac (iMac I think) to her TV. I'm thinking I need a Mini-DVI (male) to HDMI (or DVI) and a separate 3.5mm Male to Male for sound.

Answer 1

Actually it is called a MINI-DVI (not Midi as in the first part of your question), but yes it is.

I believe this is a white iMac, these had Mini-DVI (the first Alu iMacs also had Mini-DVI). This changed just around 2011 with the 2nd Generation of alu iMacs (display port) and the latest generation (Thunderbolt).

See here for details and comparision and see this schematic:

Not sure about that cable from your link though, because to me it looks like a HDMI socket. However, below is typical monitor (or TV) female DVI input socket:

I would rather expect you to buy this adaptor, which would make the socket similar to any PC video card and then use a normal DVI-DVI cable that would be used to go from a regular DVI video card to the Monitor/TV (I think this is what you mean by "DVI Male to Male"). If your friend's TV has VGA in, there is a VGA version too (link).

Regarding sound, a TV most likely has cinch input for sound (as in the picture above). There are many solutions for 3.5mm-stereo -> cinch (e.g. this).
