Review on UPTab USB-C to Mini DisplayPort Adapter 4K@60Hz (Graphite), Type C Compatible by Todd Stovall

I use this adapter with a 27" Apple Cinema Display Model A1316 and a 2018 Mac Mini. When I start the mini from sleep the adapter works fine. BUT when the Mac Mini was off I get no PICTURES on the screen after the mini completes the boot up sequence the screen is black to get a picture I have to unplug the mini display cable from the adapter and then plug it back in. This calls the mini and the display hit 'reconnect' and I get the picture. As you can imagine it's a hassle and I'm not too keen on disconnecting and reconnecting cables due to wear and tear. I haven't read any other reviews where others have this Having problem but I'm wondering if it's because very few people ever shut down their computers and don't realize the problem exists.
