I recently got a u3419w. I connected my keyboard and mouse to the usb hub and switch inputs between my PC on DP and the Macbook on usb-c. When I am using the PC with the Mac connected, it eventually goes to sleep and despite being on the DP input, a "usb-c input disconnected" message appears. Mildly annoying but no big deal. However this apparently is enough to trigger a wake on the Macbook and a few seconds later I get a "usb-c connected" message. After a minute or two the Mac goes back to sleep and the cycle continues. As you can imagine, this becomes extremely annoying and I am forced to disconnect the Mac and stop it charging. There seems to be a number of posts around about similar issues with similar Dell monitors, although no one seems to mention that they see these annoying status messages for one input while using another. Any advice on how to fix this issue? Thanks
