    Hello,

    I am a complete macnoob that is trying to understand the logic in the Mac-connectors world.
    Here is the case:
    I received an older Imac (not sure which type) that still functions correctly but sometimes blocks when in use. I'd like to use it just as a monitor, basically a tv-screen.
    Therefor I need to input an hdmi (from the tv decoder) or vga (from my laptop).

    Firstly, will this work? Can such an imac easily be used as a 'dumb' screen?

    Secondly, I bought what seemed to me a matching piece that fits within the Imac (thunderbolt) to hdmi female.
    (http://www.lightinthebox.com/nl/thunderbolt-male-naar-hdmi-v1-4-vrouwelijke-kabel-wit-voor-macbook-air-macbook-pro-imac-mac-mini-0-3-m_p732188.html?litb_from=crm_payment_shipped&user_email=vdl.jasper@gmail.com&merchant=1&customer_id=17645907&utm_source=nl-sysmail&utm_medium=newsletter&utm_campaign=LITB20160428)
    Put turns out it's not a perfect match, the port in this imac turns out to be something slightly different then thunderbolt.

    So I figured it might be the mini displayport that is on this imac?
    In that case I just need to buy this cable:

    Any hints on this one?

    While the older aluminum/silver iMacs had mini-display port, the even earlier white/plastic iMacs had mini-DVI and do not support targeted display mode. The OP's pic looks like one of the white iMacs and the display jack looks like mini-DVI.

    Correct. That is NOT mini-DisplayPort. It is mini-DVI on the iMac.

    That's why the adapter does not fit. This is mini-DVI:

    That iMac can't work as a monitor anyway. Even if you bought the right adapter, all you would be able do is to attach a second monitor.
