Anyone else seen this? Over the course of my work day, I connect my 15" tMBP to various screens and projectors, as I move around at work. I use several means of connecting depending on the device - HDMI dongle, VGA dongle, TB3->TB2 connector, and a USB-C->DisplayPort cable. No matter what the connector, I've been having repeated problems, all variants of: The external display just plain isn't recognized. Need to take the connector out, put it back in, sometimes several times. The external display is recognized, but the all I get is a solid grey screen or solid blue screen, and the tMBP freezes and needs to be rebooted. The tMBP just outright crashes. I'm having to reboot my tMBP at least once a day due to these issues. If it were just one dongle, I'd just replace it. But it happens no matter which one I'm using. Anyone else having this kind of issue?
