Help with imac 2017 connections

[Paulinfo]

Please tell me if this already answered. I have 2011 imac & I'm buying a imac 2017, want to know if the 2017 has a displayport or have they moved it to usb-c & have they a headphone socket to doc to a 5.1 surround system.

If you visit apple.com imac specs you'll get your answer fairly easily.

USB-c port supports external displays by using a "USB-c to displayport" cable. I don't believe the previous "minidisplayport to displayport" type cables will work on the new ones.

AFAIK, the headphone jack supports 2-channel audio only.
No support for 5.1 that way (perhaps you can get it through USB).

This might offer some assistance for 5.1 audio - https://forums.macrumors.com/threads/how-can-i-connect-my-5-1-speakers-to-my-2017-imac.2053113/
