I have a caldigit element thunderbolt 4 hub (thunderbolt 3 compatible) connected with a caldigit tb4 cable to the right rear usb-c expansion port on my laptop, and a plugable brand (and highly recommended) usb-c to hdmi cable routed from the hub to the monitor.
I have some issues with the monitor shutting off and not turning on at system sleep / display turnoff events. Has anyone else had similar problems? The caldigit hub shows up as available in my Thunderbolt devices on port 3, and stays connected. (and for the record I’m not ruling out issues with the Caldigit hub or the wires, I may send this one back and request another of both the wires and the hub)
(1) When I suspend my system and put it to sleep, it disconnects from thunderbolt and it does not reconnect to the display. Sometimes I have to reboot, or suspend and un-suspend a few times to get it started.
(2) When I reconnect my thunderbolt plug, sometimes it connects and the display comes on, and sometimes it doesn’t. Sometimes it flashes on 2-3 times before it makes a stable connection.
(3) if I move the usb-c to hdmi plug from the expansion usb-c port to the usb-c hub, sometimes it won’t come on the display, but it shows as available on my windows display settings.
(4) Sometimes it just takes connecting and reconnecting the usb-c to hdmi cord on the back of the hub to start working again and sometimes not.
My guess is something happens when the display / sleep function happens that doesn’t allow the display to come back on. When I go into my windows display settings I actually see the 2nd display, but the monitor is totally blank.
Something is happening, and I’m wondering if there are advanced settings or certain things I am overlooking, or is this a hardware issue with the framework at this point? The performance of these high-quality TB4-rated products in concert with the framework is unreliable and unpredictable.
