I have the Samsung S26 Ultra

I am trying to get two extended monitors with a multifunctional hub.

I am able to get one extended monitor, the other is mirrored. Has anyone been able to get two extended monitors without using the Samsung device as a screen?

Hi John5467,

We completely understand how important this setup is to your daily workflow. Many of you rely on DeX as your primary workstation, and having true dual extended screen real estate is crucial for maximum productivity and multitasking.

Samsung DeX does not support dual extended external monitors. If you connect your Galaxy S26 Ultra to a multi-port USB-C hub with two monitors attached, the system will always result in one extended screen and one mirrored screen.

This is a built-in architecture limitation within the Android and DeX software environments. Currently, the operating system is designed to output only a single external desktop frame buffer.
