U3225QE, DDPM HotKey KVM switching fail
Hello
I am a new U3225QE owner.
I have two computers connected to the display - a Macbook Pro via Thunderbolt and a PC using DisplayPort and USB-C.
On the Mac side, I'm able to set a hotkey in DDPM and it switches over to the PC.
On the PC side, I'm able to set a hotkey in DDPM and it remains on the PC when pressed. The screen goes blank, then displays the screen resolution, the DisplayPort input, etc, but it never switches to the Mac.
If the KVM hotkey feature works for you on PC, was there any additional configuration required? It doesn't matter here which computer is configured as PC1 and PC2 in the DDPM UI. There is no network KVM configured in the DDPM UI.
The local DDPM version 2.1.2.12 (which consumes a mind-blowing 643MB).
Thanks in advance

Thus far, my general impression is that the KVM in the U3224QE is much worse than the KVM in the U3415W it replaces. Even the built-in controls are poor - if I turn on the PC here, the monitor prompts to switch to Displayport. I accept, then it shows a blank screen and a message that reads:
"No DP from your device. Press any key on the keyboard to wake up. If there is no display, press the monitor joystick to open up the Menu and select the correct input source."
The only way to see the display is to input select back to Thunderbolt, then input select back to DisplayPort. This is utter pants.
A major part of the reason I bought a Dell monitor was for my obvious incorrect perception that Dell knew how to make integrated KVMs. Obviously not.

There appear to be NO OPTIONS at all for contacting Dell. I've called support and it tells me I can find online support. I can find no online support other than this forum. I am going to be returning the monitor in all likelihood as NOT FIT FOR PURPOSE.
