Question: Does the iMac 27' 5K 2017 unable to monitor a USB-C to DVI signal ? (bis)
I've experienced trouble with StarTech USB-C to DVI adapter on all our iMac 27' 5K, model 2017.
It is impossible to see a video signal on it with any monitor or videoprojector.
The company doesn't understand why it don't works.
Have seen that a Apple Cinema Display isn't supported by those iMacs.
Have also note that Apple only propose USB-C to HDMI or USB-C to VGA adapters.
No Apple USB-C to DVI adapters yet.
So it remains a question: is there a known issue between brand new iMac 27' 5K model 2017 (first iMac model with USB-C connectors, thunderbolt 3 signal inside) and DVI signal ?
After lots of tests from MacOS 10.12.6 (Sierra) to 10.13.0 (High Sierra), with monitors & videoprojectors, I'm more on a iMac hardware problem.
One more thing 😉 , Sierra propose an hardware update when you plug a Apple USB-C to VGA adapter but it won't correct the bug on USB-C to DVI adapters...
