My understanding is that it's specifically the thunderbolt-2 adapter that doesn't support further adapting to other alternate mode mechanisms. This might be because of incompatibilities between TB2 and TB3/USB3.1 alternate mode implementations?
It doesn't mean it can't do DP over a specific type-c to DP cable/dongle, which presumably are or will be a thing (eg: https://store.google.com/product/usb_type_c_to_displayport_cable https://store.google.com/product/usb_type_c_to_displayport_c...). The author appears to want to wait for docks that do both DP and power delivery, if I understand correctly.
- lvh 10y agoYou're correct on both counts: Apple suggested I purchased such a dongle. Unfortunately, as per the post, that's not easy; most USB-C devices currently available don't work. I'm holding out specifically for rMBP2016-compatible devices; and it seems a little silly not to wait for a dock now and get the tempting one-cable experience.
- rayiner 10y agoThere are USB-C to DisplayPort cables. You need some sort of converting cable anyway--the old MBP had Mini DisplayPort and I've never seen a monitor with a MiniDP input.
- lvh 10y ago(Author here) The Dell P2515Q I have has both DisplayPort and mDP2 in and out (for chaining).
- slantyyz 10y agoAs does the Dell 4K P2715Q. I have to admit, my assumption for the monitor having both sizes of the display port (vs both being full sized DP) and including a DP-> mDp cable were so that the monitor worked out of the box no matter what type of port the source computer had. All possible combinations are satisfied.

- ProZsolt 10y agoOlder Macbook Pros also supported chining, but not the OS. It's working under Windows.
- pxndx 10y agoI have an Asus mg279q with both a DP and a miniDP input. The provided cable is a DP to miniDP, so you can plug most devices with a single cable (just reverse it). I guess other monitors from the same line have miniDP inputs too.
- randallsquared 10y agoMy Philips bdm4065uc has both DP and mDP.
- mikeash 10y agoYes, it sounds like it's doable, it's just insane that Apple doesn't offer the necessary adapter (and further insane that Apple doesn't make it clear that the TB2 adapter won't do the job). I'm OK with the computer using USB-C exclusively, but Apple needs to make adapters available for other common ports. Relying on third parties for something as common as DisplayPort is not good.
- teilo 10y agoIf you have an existing Thunderbolt dock, you can use the 3-to-2 adapter, and just plug the DisplayPort monitor into the other Thunderbolt port on the dock. I do not know why this works, but it does.
