I am using a chromecast ultra and my Galaxy S7 to screen mirror Zwift on my fullHDTV (no 4K)
This works but with a great deal of pixelisation in the distance. On the screen of the telephone it looks fine though. On the TV, it is somewhat blurrry when pedaling.
should I change my telephone for a S9? should I use a PC instead?
Is “native chromecast” being developed at zwift ?
note: Also on the S7, some terrain is missing, grass and snow take over the road.
Sorry, I checked and apparently the S7 was the one where they disabled MHL (mobile high-definition link) and opted for wireless display. It came back on the S8 when they realized wireless mirror is hopelessly slow. The cable you linked is for newer phones with USB-C ports.
So I guess you’re stuck with using the Chromecast for now.
