Scaling display for Mac OSX in VMWare

I'm running Mac OSX 10.10 under VMWare 12, my monitor is a 4K 27" display - so the text is tiny.

I opened System Preference -> Display -> Scaled, but the only option available is 3840 x 2160 (my 4K resolution).

Is there a tool / a way to scale Mac OSX under VMWare ?

There are multiple tools for this problem:

• Retina Display Manager (https://github.com/avibrazil/RDM): Free, with GUI.
• SwitchResX (http://www.madrau.com/) : not free, 15-day trial, lots of options
• cscreen: free, no GUI - install homebrew then run brew cask install cscreen

So far, I found RDM it's the best: it's free and offer a nice GUI to choose the resolution.
