[BUG] OAK D Pro W PoE starts with depthai_demo but cant

[hamzaMahdi]

Describe the bug OAK-D-Pro-W-PoE starts with depthai demo (pulled latest from master) but only the RGB camera works properly. Left monochrome shows a white image outdoors. This is in contrast to typical behaviour from the OAK-D-Pro that I have which works outdoor at daytime. Right monochrome camera does not work at all.

To Reproduce Steps to reproduce the behavior:

1. Update the camera bootloader: https://docs.luxonis.com/projects/api/en/latest/components/bootloader/#device-manager
2. pull latest depthai repo and install requirements
3. python3 depthai_demo.py
4. demo runs but has issue described above

Expected behavior depthai demo runs properly and monochrome cameras work both indoors and outdoors.

Just an update, I ran the mono preview demo (https://docs.luxonis.com/projects/api/en/latest/samples/MonoCamera/mono_preview/), and it doesnt not have that issue. Although I am using the same python environment as the depthai_demo.

Both monocameras output correctly and work outdoors without being "overwhelmed", i.e. whithout showing complete white image.

Hi @hamzaMahdi , On the initial post; I believe left remains white because right isn't showing anything, and these two stereo cameras have hardware sync between them - that's why when 1 doesn't work, they both "don't work". Really interesting that it does work for the mono camera preview. Could you try using python3 depthai_demo.py -gt cv to force opencv gui type? I'm wondering what the cause for this issue could be. Thanks, Erik

[hamzaMahdi]

Running the python3 depthai_demo.py -gt cv command opens two windows: color and disparity check. For some reason I cannot see the "tabs" in the opencv gui.

I found the same issue. May I ask if you fix it?
