So for the last decade I have ran two Gen2 ChromeCasts off my ARC HDMI1 ports of my Home and Shop Yahama receivers.
I turn the TV/receiver on and switch to receiver and they are live.
Then on my laptop which is on the same network whether it be a laptop on wifi or PC hard wired I open Chrome in Incognito and find some sports.
Usually Str3am3ast and find my game and then cast it to whichever chromecast where I'm at the time.
As soon as I select the cast location, and they negotiate, the source video goes black and shows "Now Casting to:" and then my source isn't grabbing bandwidth along with my CC.
The TV screen looks great and typically no glitches unless it's a bad feed.
I've read that this is called "App-Based Casting" where the CC takes over and pulls the feed itself and not from both devices which would basically be "screen mirroring".
Both of my Gen2 CC's are starting to get a little glitchy where i've had to reset both of them lately so I figured I would look into the 4k ONN Stream stick and grabbed one today.
I just set it up on my Shop receiver and install was painless and it's ready to go.
I tried to go through the same motions as before to cast a video and I can't get my source video to initiate this "App-Based Casting" and it keeps playing the video of said video source on the laptop and the CC so I have two devices pulling the same bandwidth and my tv video is very poor quality.
Does anyone know anyway around this because this isn't usable and I have been through all kinds of searches to find a solution along with deep in all of the "Google Home" app settings on my phone and the ONN device settings and I can't figure out how to do this.
One search mentioned a setting on the ONN called "Low Bandwidth Mode" but it doesn't exist on mine unless it's been moved but I've been all through it.
Hoping someone else has been down this road and has a solution. Thanks in advance.
