Display Cable for old iMac mid 2007 to new iMac 2019

[laurencoupland85]

So I have a mid 2007 iMac and a new 2019 iMac and I would like to have my old one as a dual screen. However, the display port doesn't fit a normal MDP connector, it is slightly bigger, by about 1 or 2mm so I am struggling to find anything. I have just ordered a dvi - hdmi adapter which is what I was told to get but it doesn't fit the Mini display port.

Any help would be great as I need this for work and Im getting frustrated.

Thanks

In order to use your 2007 iMac for a extra display for the 2019 iMac, the 2007 iMac would have to support Target Display Mode, it does not support TDM.

Use your iMac as a display with target display mode - Apple Support

Target display mode is a feature available with certain older Mac models.

You can't use either of these two iMacs as secondary displays.
