Review on 🔌 UGREEN 4K Mini DisplayPort to HDMI DVI VGA Adapter - Thunderbolt Compatible 3-in-1 Converter for Mac, 2015 MacBook Pro Air, iMac, Surface Pro3 Pro4, Google Chromebook, PC - Black by Ryan Arthur

My 2012 Macbook Pro with DVI cable, I was surprised at how tight the DVI connector is on this thing compared to the other adapter I have, that fits and slides in smoothly. I really have to click on this to fully land it (manufacturing tolerance/quality control?). Connecting to my external monitor + my Macbook Pro's DVI cable was causing problems. Intermittent display signal; Sometimes it works when all the cables are in, sometimes it doesn't. I didn't check the HDMI or VGA port. It's not what I expected and will most likely come back for another. piss off!
