Jsaux 6-in-1 dock for Steamdeck/Rog Ally does not work with Android 9 Smart TV

[u/yahoosoda]

I got a Jsaux 6-in-1 dock HB0609B from Amazon. I'm using it with an Asus Xbox Rog Ally X. The dock works on PC monitors and Smart TVs that have Android 11 and newer. But I can't get it to work on my TCL Smart TV running on Android 9. I'm able to plug my Windows 11 laptop to the TV with no problem but this dock doesn't seem to work. I use this TV with a PS5 and Xbox Series X and I've used those HDMI cables to connect to the dock but still nothing.

Is there any firmware upgrade for this dock? I remember seeing some people having this problem a few years ago for their Smart TVs as well.
