1. I can connect to monitor #2 (Iyama) with HDMI out (laptop) to HDMI in (monitor) works OK.
2. When I connect to monitor #2 (Iyama, different model) with mini displayport (out) to displayport (in), monitor#2 cannot detect the incoming feed.
3. When I disconnect monitor#1, monitor #2 jumps into life and displays OK.
So I can use a single monitor HDMI>HDMI, or miniDP>DP, but I cannot use both concurrently. [Also, if I connect monitor #2 with Thunderport (out) > HDMI adapter > HDMI in, both monitors work fine concurrently... but I have to uncouple the adapter and recouple each time to make the monitor detect it!]
Any ideas why the HDMI and DP connections cannot work concurrently, and how I can get them to work? All drivers and BIOS updated to current version. The notebook has onboard intel GPU and Nvidoa GPU. The blurb seems to say the intel will support 3 displays, it is silent about the NVidia one. Does the NVidia only serve one external display, and I need to use the Intel GPU to use 2 external displays? That seems nuts!
Why don't I want to just use the Thunderport solution? Well I could, but the sockets are smaller and flimsy and will eventually break, plus I have to decouple/recouple the adapter each time. I bought a dual output laptop specifically so I could hook up dual monitors via dedicated graphics ports and it doesnt feel such a big ask for those to work correctly? And I prefer the chunkier physical ports for ease and longevity.
