Review on Elgato Thunderbolt 3 Mini Dock - with Integrated Thunderbolt Cable, 40 Gbps, Dual 4K Support, USB 3.1 Gen 1, Gigabit Ethernet by Russell Roberson

I used this to connect my 2019 13" Macbook Pro to my 4k monitor via DisplayPort and it keeps turning the monitor on and off as well as my laptop screen. The laptop keeps trying to connect to the monitor and sometimes it works for a short time, the rest of the time it doesn't recognize it and shuts off. Did the same thing with HDMI. So I went back to my old USB-C adapter and everything works fine. I got this just for Get DisplayPort capability. It's junk. Don't buy it.
