Linux host - Setting number of guest monitors not detected in Win 10 guest

My setup:

VMWare Workstation Pro: 14.1.1 build-7528167

Host: Linux Mint 18 64bit

>uname -a

Linux lm18 4.4.0-116-generic #140-Ubuntu SMP Mon Feb 12 21:23:04 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

Host monitors: 2 (1920x1200 and 3840x2160)

Guest: Windows 10 64bit (B1709)

In VM > Settings > Display > Monitors

Setting "Use host settings..."

I can cycle through monitors to enable both displays in the guest.

All good so far.

Problem:

If I set "Specify settings for monitors" and "Number of monitors" to 4 (or some other value), this has no effect. Windows 10 display settings only sees one monitor and [Detect] monitors has no effect. What I want to achieve is exactly what is described in the help...

~~~~~~~~~~~~~~~~~~~~~~

Configuring Display Settings

Specify monitor settings

...It is also useful if you are developing a multimonitor application in a virtual machine and the host system has only one monitor. After you power on the virtual machine, the guest operating system sees the number of monitors that you specified. Select a resolution from the list or type a setting that has the format width x height, where width and height are the number of pixels.

~~~~~~~~~~~~~~~~~~~~~~

In summary, I want to ignore the host settings and define a 'virtual' 2 x 2 grid of HD 1920x1080 monitors in the Windows guest on my 4K screen

I have:

a) played with the maximum resolution and graphics memory settings to no avail.

b) reduced WxH to smaller sizes eg. 1024x768

c) uninstalled and reinstalled VM Tools as suggested in other posts

d) tried different view options

e) manually adjusted vmx settings as per other vmware topic.

Eg.

~~~~~~~~~~~~~

svga.numDisplays = "4"

svga.maxWidth = "3840"

svga.maxHeight = "2160"

svga.vramSize = "33226752"

svga.autodetect = "FALSE"

~~~~~~~~~~~~~

I'm out of ideas. Any assistance appreciated.

This is still a problem on 14.1.3 build-9474260

Does anyone know if this has been fixed in the new release?
