Mercury Transmit issue in 16.1

Same issue, Premiere working fine.

Windows 10

No luck with Mercury Transmit in either AE or Premiere 2019 (latest versions). Looks like I can get Monitor 2 to work, but not on monitor 1.

AE 2018 works fine.

Win 10 (1809)
Nvidia driver 419.35 on a 980ti
2 x Dell 1440p displays

I had horrendous problems.

Same symptoms. Discovered that AUSUS Sonic Studio Drivers cause the problem.

Now, it works as expected.

Same issue here in Windows 10. It's impossible to transmit to "Adobe Monitor 1".

I hope this is not in purpose. Premiere Pro is working just fine, as was in After Effects previous versions. Transmit is broken.

Same issue.

Three-monitor system here (arranged 3-1-2)
-Open AE prefs, click checkbox for monitor 2
-Click OK. Mercury Transmit takes over monitor 3
-Open AE prefs. Checkbox for monitor 3 is now checked, monitor 2 unchecked
-Uncheck monitor 3 and click OK. Monitor 3 returns to normal.

Worked fine in previous build of AE. Persisted through reboots. If I rearrange the monitors in either the Windows or Nvidia control panels, the monitors switch as expected, but AE always takes the left-most monitor. I even tried swapping cables on the back of the computer to a 1-3-2 configuration, but AE now takes monitor 1; always the left-most monitor in my setup.
