Weird. I have a work MacBook Pro m3 and a personal m1 MacBook Pro. Both are just plug and play for me. I actually have my displayed connected to a CalDigit TS3 dock and just connect different computer to the same dock.
Over HDMI I’ve got a no-signal error. I think I’ve tried display port or something else and got very bad ghosting and a kind of very bad contrast issue. You couldn’t really read text(unlike what I’ve seen on YouTube videos). Tried different kinds of settings still couldn’t get it into a working state. Like it needs a special driver or something like that.
