I'm new to this area and slightly baffled. I've just bought a Dell Ultrasharp U2715H display to connect to my 13 inch mid 2012 MBP. I just need it as a bigger monitor for word docs and web sites. I might later upgrade to the latest 13 inch MBP but for now I've no idea how to set up the monitor.

I've bought a mini displayport male to HDMI female 4kx2k adapter to use with an HDMI cable but it's not working very well (nothing usable). My MBP is running OS X El Capitan version 10.11.6 and the graphics card looks to be Intel HD Graphics 4000 1536MD. I've 4GB of memory installed.

I've hunted around and tried to google a route through this but I'm not technical enough. I just want the cheapest, easiest way to get this monitor up and running.

How can I connect my 13" MacBook Pro (mid 2012) to my Dell U2715H display?


Try using an HDMI to HDMI cable (or other) to check that the combination cable you are using isn't broken in some way.

I have a new (mid-2017) MacBook Pro 13" with touchbar and found that certain combinations just don't work when I connect to the same version Dell monitor. For example I bought a USB C to HDMI cable link here, and it will not work. I'm not technical either but believe it or not, there are different USB C settings! The website now says their new cable doesn't work with MacBook 2017 models, after I informed them. They said that they will now produce one that will.

Therefore, if changing the cable (borrow one from a friend for an hour) doesn't cure your problem then you may be experiencing similar issues to mine.

Additionally, you now have information to avoid my mistake if you buy a new MBP and use your Dell monitor :-)

Hope this helps.
