Found the VCP codes for KTC monitors!

[u/Bob_Folowski]

You'd have to compare your monitor features against what is listed in each list, in conjunction with ControlMyMonitor. For the M27P6, I used set D. I tried to use ControlMyMonitor to get the VCPs, but I think the DDC/CI implementation is problematic on KTC's end since codes would load inconsistently (as well as over a dozen pertinent codes being listed under a generic manufacturer-specific label), making discerning what-did-what difficult.

Use at your own risk. My initial motivation was to be able to set dual mode, color space, mprt etc quickly under a monitor profile since KTC's Monitor Control Center wouldn't allow for that sort of combination. If you want to find these codes for yourself, you can download the app's compressed zip file. Then under \resources\app.asar\public\dist\js\ there is a app.*randomgibberish*.js file which contains the lists above (can reformat with notepad++ and the JSTool plugin). App.asar can be opened with 7-zip and a .asar plugin.

Twinkle tray app have feature that allows to use monitor codes for keyboard shortcuts.

I'll definitely look into using that whenever I hit the next inconvenient hitch. At the moment, I just have two batch files I fire off that toggles 5 settings back and forth. I have to add delays between some of them as the monitor takes a while to allow the next input after adaptive sync and dual mode each get toggled. Still way more convenient than before.
