My 7.1 is a week out and my Nano XDR display is 6 weeks out. Im trying to figure out what to use as a display for 5 weeks. Can I use the Luna Display USB-C module plugged into the 7.1 and use my Late 2015 iMac 5k as the display? The 2015 does not have thunderbolt 3 or display port so Im trying to figure out what to do.
