Solved PC (Windows 10) To MAC Cinema Display Monitor

Hello – is it possible does anyone know to attach an older style Macintosh cinema dispay 24″ monitor to a Lenovo ThinkCentre M92p PC. The PC has a display port as well as a vga output. I bought an adapter to link to the monitor via the display port to the DVI connector on the Mac monitor but no dice. Is this because the adapter is passive and needs to be active, perhaps? Or are MAC monitors more awkward?

I’d like to use the MAC as the only monitor ideally – not too worried about dual dispay.

All help gratefully received!
