Display Port Adapter Not Working - 2016 MacBook Pro Touch Bar

I received my shinny new 15" MBP touch bar yesterday.
Currently I have a dell ultra wide monitor 34" along with a 27" Asus monitor.
I bought a thunderbolt 3 to thunderbolt 2 adapter at the Apple Store and can not get the monitor to turn on with the display cable for the life of me.
HDMI works but I wanted to daisy chain through display port MBP --> Dell Monitor --> Asus Monitor.
The Apple Store does not have any ideas so I came here.

Any idea's or what cable / adapter would work?

The Apple Store adapter reviews complain about the same issues I am having.

The docs are a little subtle about it, but yes. That is a Thunderbolt 2 not displayport adapter. They don't seem to make an adapter for displayport as such, but you can get USBC->displayport cables pretty easily.

That stinks. I use 2 Dell Ultrasharps through MiniDP, so this might be a deal breaker for me.

Anybody have any insight on a MiniDP > TB3 cable or adapter available? Without that I suppose I'm going to have to cancel my order.

I'm in the same boat, two dell Ultrasharps using DP for my old Macbook Pro. There are some USB-C to mini-DP adapters on amazon, but they're all sketchy no-name Chinese ones. I instead ordered just a single USB-C to normal DP adapter for the moment, but long term I'll be buying a dock once I can decide on which one (since OS X cant handle dual displays through a USB-C dock due to some DP-MST driver limitation).

It's not minidp, it's full-sized DP, but it works fine with my displayport monitor. I've never actually seen the monitor-end input be minidp, I've just seen minidp->dp cables.
 
I have a $20 cablematters from Amazon usb-c to full size display port cable (not adaptor) connecting from my 13TB to Dell 24inch 4k screen. It's been rock solid for 2 days straight. 60hz and all.

As I'm not aware of any good USB C to miniDP cables or adapters, I'd suggest using the full size DP connection that's on the monitors. There are some good cable solutions for this from Monoprice/Google. Adapters are a little cheaper than the cables if you don't mind the bulk.

Can't these run off HDMI as well?

They can ya, but arguably the current HDMI solutions for USB-C are worse than the DisplayPort ones. Hopefully that will change when some HDMI-alternate mode cables start showing up.
 
Glad to have found this post - went through 40 minutes with Apple Support and they couldn't identify the problem with my 2016 MacBook Pro TB with Thunderbolt 3->2 dongle and miniDP to DP cable connected to a Dell P2715Q 4k monitor.

Does anyone have a link for the aforementioned cable matters $20 USB-C to DP cable? Sounds like that would be the perfect solution.

Cheers,

Is daisy chaining possible? If I buy a USB-C to Displayport cable and hook it up to my Dell U2415 that is daisy chained to a second U2415, will that work? Or would I have to buy two cables?
 
It's written on Apple's site that TB3->TB3 adapter is NOT for connecting mini DP displays. You have to buy a specific cable USB C (your MBP, obviously) to DisplayPort (your Dell).
 
Reviving this thread with a conundrum in the same category:
I used to have a MBP 15"(2016 with touch bar) to USB-C/Display Port-adapter to 5m Displayport cable to my Asus P328 monitor.
Now I have replaced only the computer, to a new MBP 15" (2017 with touch bar). Now for some reason the display doesnt work, even though settings and setup are identical. Tried SMC, PRAM, Safe Mode and every manner of connecting and disconnecting cables.
All the USB-C ports on the MBP seems to be working, I have no idea what is different (apart from the processors in the new one being Kaby Lake)
Any ideas??
 
I've got no suggestions for your situation, but I'm glad you revived this thread because I'll be dealing with the same issues as well. I currently have a 2015 15" MacBook Pro that I run 2 Dell 2415 4K monitors out of the 2 thunderbolt 2/mini display ports. I have a 2017 15" MacBook Pro on its way and I really don't know what the best setup would be to replicate what I'm currently using.

Since there are only 4 ports on the new MacBook, I can't really replicate what I'm currently doing. Is the solution to plug in the 2 cables, charger, usb hub and thats it? This wouldn't be so bad if all 4 ports were on the left side. lol. As is, that'd put wires in front of my landscape display.

Is there a dock, thats not $500, out there that will adapt 2 display ports? Seriously, at that price, I'd just figure out an external GPU and hook both of them up that way...

What's the ideal way to connect 2 4K monitors to these new 15" MacBook Pro's?
