mac mini 2 displays from thunderbolt

[littlepigboy5]

I am hooking up my mac mini and windows pc (gtx 970)  to a monitor via a displayport kvm. When I go from my monitor to the kvm to the mac, it works fine, but if I try going from the monitor to the kvm to the PC, there is. No signal. I then tried just going straight to the pc from the Monitor, and that didn't work. The monitor is hdmi by the way, so I am using an hdmi to displayport cable which, again, works fine on the Mac mini.

might sound dumb, but is your computer actually sending signal to kvm? it might not be able to auto detect that a cable is plugged in and you might have to use the "detect displays" function under your display settings in windows

the dectect button is what i am talking about

 

 

 

if this doesnt work, it could just be some quirk with your adapter

Rare case of shorting the display port on the card maybe?

I kept re routing the cables and I got it to work with all 3 of my monitors (i left out my other 2 monitors for simplicity), but now one of my 1080p displays is only being registered as 800x600.  Is that because displayport can't handle 3 displays at 1080p 60hz?

I am trying to get 2 displays to work out of just the thunderbolt port on my mac mini.  I realize that i could use the thunderbolt and hdmi ports simultaneously, but I can't because I am using this with a displayport KVM.  When I turn on the mac mini, the display's mirror one another, but the mac mini is registering them as just 1 display so I can't set up multiple monitors within the OS.  The setup is Mac mini thunderbolt do the Displayport KVM to a displayport 1x2 splitter to the monitors.  The other machine hooked up to the KVM works fine off of 1 display port on my graphics card, but for some reason the mac mini is showing the same image on both displays (mirror).  Any ideas?

What monitors, How are you splitting the image?

 

You can't normally just do this unless you have a display port hub, and they might not work with kvms. Id get a second kvm.

You need a monitor with DP MST in order to daisy chain off one Thunderbolt port.

The hub i am using is DP MST.  That's why the windows PC is working flawlessly.  Thunderbolt should be able to handle as much if not more bandwidth than a single DP on my GPU, which is why i'm confused.

I dug a little deeper and if I took that at face value, Mac Minis don't support MST.

 

WELP.

it seems unlikely, it has intel iris graphics which on other computers can support MST.

I attatched a diagram to the original post

But this is Apple. Chances are if it's not on their official support list, then that's it.
