    So I'm planning to buy Apple's multiport adaptor and a 1440p monitor (to use with my base 2015 MacBook), but from the sounds of it it can't push 1440p at 60hz? Does anyone have any experience with this?

    The adaptor is HDMI 1.4 - so long as your monitor also has a HDMI 1.4 (or above) port then you should have no issue running 2560x1440 at 60Hz.

    From Apple's official documentation it seems to say only 1080p is possible at 60hz, but have read a couple of comments (on similar questions to mine) that say 1440p is possible. Would be good to hear confirmation from someone with the same setup before I buy a monitor/adaptor though. The monitor I'm looking at does have HDMI 1.4 ports.

    This adapter allows you to mirror your MacBook or MacBook Pro display to your HDMI-enabled TV or display in up to 1080p at 60Hz or UHD (3840 by 2160) at 30Hz.

    Yep, 1440p at 60Hz should be possible on a connection that supports 4K at 30Hz - at least mathematically!

    But yes, confirmation would be good. I would be hugely surprised if it didn't work - 1440p is an incredibly common resolution and you would hear about it in reviews if the adaptor didn't work.

    I used Apple AV multiport adapter on my 12" rMB, with HDMI cable on Dell U2715H monitor, worked with no problems at 2560x1440 @60Hz

    another question about the multiport adapter: can it pass through audio as well as video? I have my macbook connected through the adapter to a monitor, and have external speakers also connected through the monitor - but am not able to play sound from the macbook through them. I have to connect the speakers directly into the macbook to get any sound, is that you guys' experience too?

    I made a thread in the mac accessories forum asking about it, no one seems to have a definitive answer though:

    I have a similar setup with yours, but the monitor is Dell U2515H. Yes, it plays sound on my external speakers through the 3.5 jack on the monitor. Make sure you plug in the 3.5 from the subwoofer to the monitor, and the 3.5 from the speakers to the volume controller (at least that's what works on my simple Logitech speakers, 2 small speakers and a subwoofer). I'll have a look again when I get home, I could be wrong about the 3.5 setup, but I remember I have to fiddle around with how the 3.5 jack plugged in.
