blue screen of oblivion: mDP to HDMI active adapter with 11" MB Air


#1

Hi folks, I’m trying to use the Plugable Active Mini DisplayPort to HDMI 2.0 Adapter to connect my 2013 Macbook Air 11" with a 2016 Hitachi LU43V809 TV. The Mac recognizes the display and I am able to select mirroring/non-mirroring and arrange the monitors in the Displays preference pane, as usual. However, the Hitachi screen is completely blue, and no content from the Mac shows up on it. Anything I try to slide over from the laptop’s screen to the TV just disappears into blue oblivion. Interestingly, sound is successfully passed through to the TV.

I understand that I may not be able to output to the Hitachi’s full (4K) resolution, and that is fine with me. But I would like to be able to at least see SOMETHING on the external monitor. Any ideas? Would I be better off with another (e.g., a passive) adapter? Is there some software setting I need to change somewhere, or a patch I need to install?

FYI, I have used this same TV and HDMI cable with a late-2013 MacBook Pro, with no issues, at 4K resolution and 30Hz refresh. I have also successfully used this same MB Air with a regular HD TV in the past.
