I have a MacBook Pro mid-2014 with a HDMI port and a Thunderbolt 2 port (that I beleive doubles up as a miniDP port).

I have just bought an Acer H2777HU 27 inch (2560 x 1440 pixel) monitor. It has a HDMI port, DP port and USB-C port.

It only came with a DP cable, which does not fit the miniDP port on my MacBook.

So my question is: what is the best way to connect the two, ensuring that I get the full 2560 x 1440 resolution, 60Hz refresh and can use the built in speakers?

Is it:

HDMI to HDMI (are there different sizes of HDMI?)

miniDP to DP (does this cable exist?)

Thunderbolt 2 to USB-C (does this cable exist?)   Thank you

    I’d go with the HDMI.

  • Is that because there is no conversion, simply HDMI to HDMI. Does HDMI support audio? Will HDMI support the resolution and 60Hz refresh? Are there different HDMI sizes I need to know about?

  • Are you using a Retina MacBook Pro? There's no miniDP port on the mid 2014 version. I'm typing this comment from one. HDMI is the way to go.

  • As mentioned in the opening post the Thunderbolt 2 port doubles as a miniDP port. I know because I've used it in the past as a miniDP port.

According to this answer, you are probably better off with DisplayPort.

Does USB-C to HDMI take more processing power than direct USB-C to DisplayPort?

HDMI will work, but probably only give you a 30Hz refresh rate rather than 60Hz that your system is capable of.


Use HDMI for the connection to your Acer monitor. The HDMI cable, whatever length you choose, should have the standard (Type A) connector at either end. This page at eBay has everything you need to know about HDMI.
