So for my football setup, I typically have 2-3 TVs, all with Chromecasts of varied gens/models, and a laptop casting full screen video to each. I prefer the chrome tabs to "optimize fullscreen videos" when casting since I can notice a quality difference given that my laptop isn't the most powerful.

I recently replaced my Chromecast Ultra with a Chromecast with Google TV. However, on football days, the new Chromecast doesn't seem to be able to handle the stream as an optimized video. It always drops back to screen mirroring. Meanwhile, my 1st gen Chromecast and my 2nd gen Chromecast can handle the optimized stream no problem.

Anyone else running into this problem or is it just me? Also, any idea what I could do to fix it?
