Lengthy black screen after playback

[crusher11 1237]

Everything was fine yesterday, but today most of the time when I finish watching something the screen stays black for a lengthy period of time. Sometimes 30 seconds, sometimes over a minute.

I'm running the universal Android app on my NVIDIA Shied. Tried rebooting the Shield, it didn't help. I can flick my AVR over to a different input and it quickly pops up, going back to the Shield's input takes be back to the black screen.

Not sure if it's an Emby issue or a Shield issue, or how to try and figure that out. My first thought was HDMI trouble but playback start is always fine.

My guess is that the display mode is changing back.   Have you started watching more DV or HDR stuff?  Do you have match framerate/resolution selected?

Nothing has changed. I'm calibrating my audio system at the moment, so I'm playing the audio sweeps from the Spatial Audio Calibration Toolkit. It's taking me longer to sweep two speakers tonight than it took me to sweep all nine last night.

Even coming out of HDR, it's usually a couple of seconds at most. It shouldn't be taking over a minute.

Just swept a speaker. Got a black screen after it finished. I set up the calibration software ready for the next measurement, waited around for 30 seconds or so, got up, went to the other room to grab my phone, pulled up the stopwatch app, and started timing. The screen came back on one minute and 37 one hundredths of a second later . 

The next one was too quick for me to time . The one after that was 1:32.15.
