## Product: Samsung Galaxy S26 Ultra
**Brand:** Samsung

DeX on the S26 Ultra can't extend your desktop across multiple monitors. If you plug into two screens, they just mirror each other.

**What actually works:**

One external monitor works great. You can also use your phone as a secondary display alongside that external monitor. So you have DeX running on a TV while your phone shows different apps beside it.

That's technically two screens, just not two external screens.

**The virtual desktop workaround:**

Samsung added four virtual desktop spaces on the S26 Ultra's DeX. Each space holds up to five apps. Quickly swipe between spaces to access different workflows.

Not the same as three physical monitors, but it helps manage multiple tasks.

**Why this limitation exists:**

USB-C can theoretically support multiple displays. Samsung just hasn't implemented extended multi-monitor mode for DeX yet.

**What DeX is good for:**

Think of it as a portable workstation that outputs to one big screen. Hotel room TV? Perfect. Conference room monitor? Great. Your office with three monitors? Not the right tool.

With the S26 Ultra's processor, DeX runs smoother than previous versions. Wireless DeX has lower latency. Window management is better.

**For multi-monitor setups:**

If you need to stretch across two or three screens, you need a laptop or desktop. DeX is designed for portable productivity with one external display.

Samsung might add multi-monitor support in a future update, but it's not available now.
