Mercury Transmit issue in 16.1

this issue is still happening even when installing 16.1.1. Mercury Transmit defaults to monitor 2.

Mac Pro (late 2013)
OS 10.14.4
2.7 GHz 12-Core Intel Xeon E5
64 GB 1866 MHz DDR3
AMD FirePro D700 6 GB

When I choose Enable Mercury Transmit -- then Adobe Monitor 1: 2560x1440 -- click ok. The monitor I am able to preview on is not the monitor I selected.

So, I go back and check the setting and it has moved my checked box to another monitor (the one that it is using to preview) but I did not select that one. And, if I choose Adobe Monitor 2: 2560x1440 -- I get nothing.

What happened? Was all good until I went to Mojave and AE 16.1.1

Same here on a Windows 10 Pro system, 32GB RAM, i7-2600K processor, with GTX770 card (driver 417.35). In addition, I noticed that the order of options in the Mercury Transmit panel isn't always consistent. In any event I am experiencing the same as the OP - my system insists on defaulting to the same monitor that I use as my main monitor for mercury transmit (in my case, monitor 2 is my main monitor, if that's relevant. Windows seems to insist on calling my second, smaller monitor monitor 1). If I attempt to change it, it either reverts back to making my main monitor the choice or drops the selection altogether. In all cases, the / key does not activate the preview monitor.

Same here. Glad I'm not the only one who noticed this.

Win10,
NVidia GTX1050 Ti
RAM: 32 GB

NVIDIA GeForce GTX 1060
driver 419.67
Windows 10 Pro 64-bit (10.0, Build 17763)

Sigh.. once again... Mercury Transmit does not... well... work...

So, ok... this time:

Win10,
NVidia GTX1080
RAM: 32 GB
i7-6700K @4GHz

- I open AE.
- No Mercury transmit.
- I go into settings.
- I enable one of the screens for mercury transmit (which one, I don't know, because the- numbering in AE does not correspond to what Windows says, so it's just trial and error)
- I start playback. No full screen.
- I move the main window to another screen because I know this has in the past triggered Transmit to whatever the screen it feels is monitor nr 1 or whatever.

Here paths diverge. It's either:
- Sometimes I get transmit to the wrong monitor. So I try to change the active monitor. I save. I close the settings. I do the whole playback and moving windows around dance again. The playback remains in the wrong one (it seems to prefer monitor 3 in the settings... which is Monitor 2 in windows)
- Or sometimes it has inexplicably deselected ALL the monitors in the video preview settings.Why? I have no idea. I did not do that. This was AE's doing. I saved with monitor 1 or 2 enabled.

Please. Adobe. If you are going to have this feature. The Mercury Transmit. When are you going to make it work as expected? When are we going to be able to rely on it working at all?

Running 3 monitors under Win 10.
3x Nvidia GPU's - 1070 Ti's.
Main(#1) and #3 monitor plugged into GPU #1.
#2 monitor plugged in to GPU #2
All working under Nvidia driver version: 416.34

I can get Mercury Transmit previews on monitor #3, but not on monitor #2.
