I have a projector installation where the client is using a new 2019 iMac that I just replaced the old XGA projector with a 1080p Sony model. The existing "no-name" USB-C to HDMI adapter is causing flickering now that it has to work a little harder.
I ran the system on a Win10 laptop with direct HDMI and it worked great. I'm tempted to purchase the Apple brand USB-C Digital AV adapter but its not getting glowing reviews on the their website. Any brands or models you prefer that convert USB-C to HDMI?
