Can I use my Windows laptop screen as a secondary (or primary) monitor for my Mac Mini M1? It is a HP Zbook X2 and has 2x Thunderbolt 3 Ports, 1x HDMI port, 1x USB 3 port. I am pretty sure it is possible with a Samsung Tab S7.

I own an old macbook pro (late 2011) that doesn't have an HDMI port so I bought a Thunderbolt to HDMI adapter to use a second display (LG Monitor). So far I have bought 3 adapters from different brands and all of them have stopped working after a week of use. The display stays blank with a "No...

Hi, I have a 23" Apple Cinema display that I want to use as a second monitor for my new 2017 27" 5K iMac. What adapter do I need to make this work? Thank you! A quick update......I've found one USB-C to DVI (Plugable) that others have said works for the exact combo that I have, so I'll assume...

I am almost ready to switch from an Mac Pro 1,1 to a 27' Retina iMac and am intending to connect my existing 23" ACD as a secondary monitor. Would it benefit this set up to go for the 4GB video card or is the standard option sufficient. The machine would be used principally for Logic Pro and...
