PG39WCDM KVM Switch not Switching Keyboard/Mouse and Video

[JezZzaH]

I have two PC''s connected to my new PG39WCDM Monitor, which I bought specifically as it has a built-in KVM. However, I cannot get the KVM switch to switch the input/output with a single button. When I switch the KVM, it only switches the Keyboard and Mouse to another port, but the video remains on the same PC. This means that I then have to manually switch the Video Input on the monitor, which is very cumbersome.  

I've also tried to setup the DisplayWidget, to use Keyboard Shortcuts, but that has the same limitation that you need to switch the KVM and the Video Input separately. 

Next, I tried to use the 'Customized Settings' but loading those settings, does not change the KVM or the Video Input (only the other video settings, such as brightness, saturation, etc.), so this does not work either.

The quickest way I have found now is to use the Shortcut Buttons and then assigning KVM and Input to two of those. Which now require me to press those buttons 'just' 7 times to switch from one PC to the other. 

Has anyone found a quicker way to do this? Ideally, by just pressing the Shortcut Button once?
If not, I really hope ASUS can fix this quickly in a Firmware Update as this is definitely not what I expect from a built-in KVM.

Nice to know we don't need the timeouts anyway.

Regarding the issue when switching from USB-C to DP we could simply assume that the monitor is the only display connected to either system.
You can overwrite the previous InputChange.cdm with this one if that is the case.
If it isn't I'd need you to run 

windccutil.exe detect

on a terminal window in the USB-C system and either tell me or take note of the number to the left "generic display" or similar and edit the .cmd in that system so line 8 value for monindex

is that same number

YOU DID IT! This works flawlessly!
I sometimes connect a second monitor (TV) to my Gaming PC, but never to my Work PC. 
So I'll keep your original version on the Gaming PC and use the new one on my Work PC, and it works like a charm!

Now I'll create a Hotkey for it in Windows using Powertools (unless you recommend a different way) and I''ll be able to change between systems with the touch of a button! 

THANK YOU SO MUCH! This really helps me out a lot and I hope it will help a lot of other people too!

Awesome!!
Hotkey is how I would do it as well.
Glad it helped, would have been more elegant had the monitor's drivers properly assign the display a correct 'Friendly name' for windows when connected through USB-C but you gotta do with what you have.
Also thanks to ASUS for the DDC/CI feature.

I think I have switched back and forth over 20 times just now. I can't get over how great this is.
It really works like a charm. Thank you so much for your time and effort! I really appreciate it!
