> I unfortunately had to upgrade my phone, because to drive the glasses you need to have DisplayPort Alt mode. My very cheap, very crappy old phone did not.

I also run a low spec android phone, and I tried the same brand of glasses with it. My workaround was a screencast to HDMI adapter, paired with an HDMI to to DP over USB-C. Both are cheap.

Occasionally the screencast flakes out. But when the network is working well it's pretty good.
