G S4 with multimedia (HDMI + OTG) dock - not working after power off then power on

Hi All,

I have an issue with my Galaxy S4 (CM12.1) and the Leicke Clever Dock multimedia and otg dock I'm using. If I operate the dock by the instructions (plug in usb peripherals then plug in HDMI then plug in micro usb power before plugging the phone in) it works flawlessly. If I then power off the dock leaving the phone on (i use macrodroid to set it into a low power mode) and then power up again it starts charging but wont transfer the screen to hdmi unless I pull out the phone and plug it back in.

I assume that the issue is the trigger for MHL but I cant understand whether it is something in the phone that isnt putting the usb port into mhl mode or if its the dock not doing something.

A few options:
1 - Find a new dock that enables this (im struggling to work out whether any of them can, even the official samsung one)
2 - Get the phone to enable MHL when charging (i have searched high and low and cant find anything that might be able to help
3 - Get the phone to disable and then enable the usb port (dont know if this will even solve the problem)
4 - Other (suggestions appreciated)

Im also investigating screen casting and will see if there is a route there but I will also need the OTG capability.

Cheers
Findlay
