Hello helpful forum members!

I've recently entered the world of B&O, with a Harmony 77 and Beolab 18's/19 amongst other things, and I'm wondering; is it possible to listen to music whilst also having something showing on the screen from another source? For example, listening to music on Spotify via Chromecase whilst watching something on SkyQ (with no sound).

I'm guessing the answer is no, but thought I'd check anyway.

Thanks in advance.
