Please forgive the stupid question.
I set this up by doing the Docker setup shown above, and my streamed WS 4000 had a big white bar on the right quarter of the screen.
Your instructions say to Please update your WS4KP container to use the following variable:
WSQS_settings_wide_checkbox=true"
Where do I do this? I have been working on this for about 12 hours now and I haven't found where to put this.
Here is the way I installed mine. (It works great except for the white on the right) 
docker pull ghcr.io/netbymatt/ws4kp
docker run -d \
--name ws4kp \
--restart unless-stopped \
-p 9090:8080 \
ghcr.io/netbymatt/ws4kp
docker pull ghcr.io/rice9797/ws4channels:latest
sudo docker run -d --name ws4channels --restart unless-stopped --memory="1096m" --cpus="1" -p 9798:9798 -e ZIP_CODE=06111 -e WS4KP_HOST=192.168.86.101 -e WS4KP_PORT=9090 ghcr.io/rice9797/ws4channels:latest
Thanks for your help!
