How can i connect 3 displays to Mac Pro late 2013 model all via hdmi ports ?

Hi , I need to connect 3 displays to my Mac Pro late 2013 model. One display is a 4k tv and other two are benq full HD monitors . Problem is I have gone through a lot of articles on internet regarding how to connect but still unclear. All displays have only hdmi ports . I am having 3 minidp to hdmi cable ( I guess they are passive) but via it m only getting 2 displays to work on same time .

shall I buy one active minidp port to hdmi to get the third monitor working?

one active and 2 passive cable will work for all 3 displays to run on one go ?

Mac Pro, macOS 11.6

Yes, in most cases. The issue is that the Mac produces lower voltage levels on the signals for the interfaces. when you install more than to non-DisplayPort device, the levels drop so low the display cannot see them any more. ACTIVE adapters re-drive the signals up to higher levels, for better detection.

You are limited to TWO non-DisplayPort displays. The built-in port counts as one if you connect anything to it.

Install more ACTIVE adapters to support more.
