Any Issues with External Monitor Connected Through Dock on 16” MBP?

[ugahairydawgs]

I’ve been having an issue with mine where I connect to two 27” monitors hooked up to a CalDigit TS3+. I have to connect and disconnect the Thunderbolt cable 2 or 3 times to get both monitors to come up. Similarly when I disconnect at the end of the day the screen on the laptop goes black for probably 8-10 seconds before coming back up.

I had a 2016 15” MBP before with the same setup and never saw this happening, so I don’t know if I am dealing with some kind of hardware issue on the new laptop or if it’s just some kind of software bug with the graphics driver.

Anyone else seen anything similar?

From reading here and my own experiences, multiple monitor support in general can be buggy and inconsistent, and this goes double for monitors used through docks. I am still hoping that it's essentially a Catalina issue, but who really knows?

what method (ports & adapters) are you using to connect TWO monitors through TS3 Plus? what resolutions?

They are Dell Ultrasharps running 2560x1440. One connected DP>DP. The other connected with a DP>USB-C cable. Same setup I have been using since the TS3+ was released with no issues.

We’re you in Catalina on previous machine?

I’ve had success reliably connecting two screens through the CalDigit. Although they were 4K + 1080p, and I plugged in the 1080p using DVI to HDMI to USB C plugged into the Thunderbolt 3 port on the CalDigit.

Example with five screens:
