There is none at this point that I know of. Thatbwould be a heavy load for the chipset... as it would be concurrently running three displays

Hi, is this planned to be added for galaxy S22 series?

Hi, I'm owner of Galaxy s10e with latest Android and OneUI updates. Samsung Dex gives very nice functionality to use 1 external monitor. But, when I connect to it two monitors the video output is mirrored to the second one. It would be nice to have an option to extend video output to the second monitor instead of just mirroring to it. Is there any plan to add such a functionality?

I'm connecting two monitors using usb type-c dock station.

While DeX itself doesn't support 2 external displays - it is possible to use 2 external displays with a DeX enabled smartphone and some apps then allow both displays to be used.

Here is VMware Horizon, for example, on 2 external monitors from a Note 9 a Windows 11 desktop is running on VMware Horizon and spanning both displays for a true dual monitor setup.

Here is a portable version using a lapdock- note Outlook is on one display and Word on the other.

Hi, this is actually nice suggestion. Thank you.

But the actual point is to find out if there is such a possibility on a hardware level with more powerful CPUs.

@Losingthewires, please share how you were able to get mobile VMWare Horizon to span both monitors!?

Could the same thing be achieved with the vSphere mobile app, or maybe even RDP?
