Dex on Galaxy S10+

[FanaticWS]

I have Galaxy S10+ (SM-G975W) and I'm trying to run Dex on my TV. I have proper USB-C to HDMI cable. Dex never stars I only get mirror of my phone screen. In settings there is no any Dex setting available. I also tried it with my computer monitor but it doesn't work too. What is going on? Galaxy S10+ doesn't support Dex? Mind you Dex works when connected to PC.

Anybody knows what's up?

Thanks

It really makes no difference if set to Mirroring or Dex it always mirrors. I actually went as far as Factory Reset and reinstalling whole phone...no change... disappointing..

What happened if you connect hdmi cable on your TV and try to switch the device from Samsung Dex to screen mirroring and vice versa

Could be the cable is not being recognized as being 'authentic' by the S10+ to run in DeX mode?

I don't know. My tablet works fine with this cable.

I bought this cable for my Note 10+ and it works great on my Tab S4 and my Note 10+ :(HDMI 8 K is not supported by Note 10+ and Tab S4, so don't buy 8k cable )

He also tried it on his computer screen and it don't work there too

likely the cable itself. Get a different cable and try again. My Aukey Type C to HDMI works without issue.
