Manual signal loss detection working strangely

[Lebo77]

So I have HyperHDR up and working great. I just have one problem. The lights don't turn off without manual intervention on the web page.

I have an always-on Roku Ultra as the source. It goes through an HDMI switch, to an HDMI splitter and on to the capture board.

I tried automatic calibration but that did not work, so I tried manual calibration. I set the Roku to go to an all-black screensaver after 5 minutes. Turned off the TV and waited. Backlight stayed on. Still on 30 minutes later. So I go into the HyperHDR web page to check the Live feed on the LED Visualization page. Lights go out instantly. It's as if opening the page reminded the system to check if the signal had been lost.

So I looked at the logs and no, the instant the source goes black the system detects it and switched to source "priority channel 254". I had thought a loss of signal would force it to idle state and thus the background effect (mine is set to black (0,0,0) of Priority channel 255, but no.

Any suggestions? I have reproduced this several times. Not sure if I have something misconfigured or what.

Hi
What I can say? Automatic detection definately works fine on many system and it's recommended over the manual detection (you MUST be sure about colors thresholds in manual calibration: "black" in capturing in not always real black RGB and only a part of the screen is tested compared to the automatic detection).
Most common mistake for automatic detection is to calibrate the signal for the video source and then to change the capturing resolution or capturing format or the framerate. In such situation the calibration must be done again. But there is a warning in the logs about that. So I recommend you to test again the automatic detection, try to trigger no-signal on your system and to observe the logs: without them captured while this happens cannot help more.

The DETECTION is not the issue.

I just tried it with automatic detection and am having the same issue. The logs in each case show that the system is detecting the loss of signal. The problem is that until I open the LED Visualization window on the web app, the LEDs are still on.
Here is a chunk of the logs:

This is the same behavior seen with manual detection.

OK, also have got logs even longer that shows what is happening. Without background effects:
