USB-C Digital AV Multiport Adaptor can only mirror not extend to an ext. display?

[noct]

Has anyone got the multiport adaptor on hand and can confirm for sure that it can extend to an external monitor (i want both the rMB and the ext. monitor on, not just the ext. one).?

On apple.com it did not state that it can extend:

"this adapter allows you to mirror your MacBook display to your HDMI-enabled TV or display in up to 1080p at 60Hz or UHD (3840x2160) at 30Hz. It also outputs video content like movies and captured video. "

Other old displayport adaptors clearly state it can BOTH mirror and extend.

1. I searched here and no old threads for this question.
2. Called apple and no one knows.
3. Visited an apple store and its out of stock so no one knows and can't try it out.

Very frustrating if the adaptor can EXTEND but apple makes a mistake of not stating it clearly on their website.....

And more frustrating if the $79 thingy that probably costed $8 to make cannot extend.

Would like to know the same! If it only mirrors i'm not buying it, but if it extends i might.

I use mine to extend my display to the right on an HDMI 1080p display. No issues.

Perfect - was hoping this was the case as well!

Just checked and will also confirm it works just fine.

Thanks for clearing that up! Strange wording by Apple considering it can extend as well.

I use it to extend via HDMI->DVI at 1440p on my DELL U2713HM monitor.

Can you physically connect to an external display and run a third display through an Apple TV?

hmm now that is a good question. My ATV is at home, so I cannot test it =/

Yes you can.

Hdmi > dvi & vga

Thanks to FatefulWhisper that the HDMI > DVI extends. I have the multi-port on order. Got both an HDMI > DVI cable and a HDMI > VGA adaptor. Do a lot of photography and have reason to show on TVs and projectors. Also have an SD card adaptor for the camera.

However need the HDMI > DVI to go to my external monitor. Have a cable solution that allows me to use my keyboard/trackpad to bounce between 2 computers. Will post if that works OK as well as the other adaptors.

Flying right now and find this computer to be a joy to work with while traveling.

Awesome! Any delay when moving your mouse cursor from rMB to ATV screen to ext display? Or it's all butter smooth?

Yes you can.

Wormhole Switch

noct, using wormhole switch JUC400 USB to USB, iMac to PC Laptop today and it is seamless and butter smooth. Looking to replace PC laptop with rMB with same results. Will post results after I get my multi-port adaptor.

I just got mine and it will extend, however I can only get the macbook to use the native resolution (very small). Can anyone coach me if I am doing something wrong? Thanks

No delay. Yes, it's really smooth; although w/ ATV mirroring, it will be strongly dependent upon your network connection. I have 802.11ac at 5GHz w/ a transmission rate of ~867Mbps, so there's no lag via wifi to the ATV.
