You’re going on a trip and don’t want to lug around your laptop. You have a powerful phone, a monitor in the hotel room, and an HDMI cable. What if you could use your phone like a PC? You can, and I’ve been doing it for a year. Here’s how to enable desktop mode on Android with an HDMI cable, step by step, no hassle.

What you need to use Android as a PC
Before diving in, make sure you have everything ready. Not all Android phones support video output via USB-C, and without that, there’s no desktop mode possible.
Basic requirements
- An Android phone compatible with DisplayPort Alt Mode or MHL. This is the most important thing, and the one most people forget to check. Your phone must be able to send video through its USB-C port.
- A USB-C to HDMI cable or adapter. These start at around $10. If your phone has micro-USB (older models), you need a specific MHL adapter that costs more.
- A monitor or TV with HDMI input. Any screen with HDMI works, from a $150 monitor to a hotel TV.
- Keyboard and mouse (optional but recommended). You can connect them via Bluetooth or USB through a hub.
Heads up: Not all USB-C ports support video. Budget phones often have USB-C that only charges and transfers data but doesn’t output video. Check your model on GSMArena by looking for “DisplayPort” or “MHL” in the specs.
Phones compatible with desktop mode via HDMI
The best-known models that support video output via USB-C:
- Samsung: Galaxy S8 and newer, Galaxy Note 8 and newer, Galaxy Z Fold 2+
- Motorola: Edge 30/40/50 Pro, Moto G Stylus 5G
- Huawei: Mate 10 and newer (with EMUI Desktop)
- OnePlus: Recent flagship models
- Xiaomi: Some flagship models (varies by model)
Samsung DeX: The best desktop mode experience
Samsung DeX is, without question, the most polished desktop mode implementation on Android. It’s been refined for years and works beautifully in 2026.
How to activate Samsung DeX via HDMI cable
- Connect the USB-C to HDMI adapter to your phone
- Connect the HDMI cable to the monitor
- A prompt will appear on your phone asking if you want to launch DeX
- Tap “Start DeX”
- Within 3-5 seconds, you’ll see a full desktop on the monitor
Samsung DeX’s desktop looks like Windows. It has a taskbar, start menu, support for resizable windows, and real multitasking. You can have a document on the left and a browser on the right — something impossible on the phone’s small screen.
What you can do with Samsung DeX
- Browse the internet with Chrome or Samsung Internet in full desktop mode
- Edit documents with Microsoft Office or Google Docs
- Watch videos on the monitor while using your phone for something else
- Play games with gamepad support on the big screen
- Give presentations by connecting directly to a projector
Pro tip: With Samsung DeX, your phone becomes a touchpad while the desktop displays on the monitor. You can use your finger on the phone screen to move the cursor. It’s super convenient when you don’t have a mouse.
Samsung DeX also supports wireless mode, but via HDMI cable the experience is much smoother with zero latency.
Motorola Ready For: Motorola’s alternative
Motorola has its own implementation called Ready For, and in some ways it surpasses Samsung DeX. It’s available on high-end Edge models.
How to activate Ready For via HDMI cable
- Connect the USB-C to HDMI adapter to your Motorola
- Connect to the monitor
- Select “Ready For” from the notification that appears
- Choose your mode: desktop, gaming, video chat, or connectivity
What’s interesting about Ready For is that it has specialized modes. Desktop mode is like DeX, but gaming mode optimizes the screen for gaming, and video chat mode uses your phone’s camera as a high-quality webcam for video calls on the monitor.
Differences from Samsung DeX
| Feature | Samsung DeX | Motorola Ready For |
|---|---|---|
| Desktop mode | Yes, very complete | Yes, good |
| Gaming mode | No (gaming in desktop mode) | Yes, optimized |
| Video chat mode | No specific mode | Yes, uses phone camera |
| Multi-window | Excellent | Good |
| App compatibility | Most apps | Fewer optimized apps |
| Mouse and keyboard | Excellent support | Good support |
Heads up: Motorola Ready For doesn’t work with all USB-C to HDMI adapters. Some cheap adapters aren’t recognized. If it doesn’t work, try a different adapter or an official Motorola one.
Generic options for other Android phones
If your phone isn’t Samsung or Motorola, don’t worry. There are generic alternatives, though the experience won’t be as polished.
Screen mirroring
The most universal option. You simply mirror your phone screen onto the monitor. Works with any phone that supports DisplayPort Alt Mode.
- Connect the USB-C to HDMI adapter
- Connect to the monitor
- Your phone screen automatically mirrors on the monitor
The catch: you see the same image on both screens, in vertical format. There’s no desktop mode, no improved multitasking. It’s basically watching your phone screen on a bigger display.
Download a desktop launcher
You can install apps like “Sentio Desktop” or “Taskbar” from the Play Store that transform your interface into something resembling a desktop when you connect a monitor. It’s not perfect, but much better than simple mirroring.
- Download “Taskbar” from the Play Store (it’s free)
- Set it as your default launcher
- When you connect a monitor, Taskbar shows a desktop interface
- Compatible apps open in resizable windows
Keyboard and mouse: The complete experience
For Android desktop mode to be truly useful, you need a keyboard and mouse. Without them, you’re limited to your phone’s touch screen, which is uncomfortable on a large display.
Connection options
Bluetooth (recommended): Wireless keyboard and mouse without a dongle. Connect directly from your phone’s Bluetooth settings. Cleanest option and doesn’t use USB ports.
USB via hub: Connect a USB-C hub to the HDMI adapter and plug in wired keyboard and mouse. Some HDMI adapters already include additional USB ports, which is ideal.
Keyboard with trackpad: There are Bluetooth keyboards with built-in trackpads. The Logitech K400 is cheap and works perfectly with Android.
| Option | Average price | Comfort | Portability |
|---|---|---|---|
| BT keyboard + BT mouse | $30-50 | Very high | High |
| USB-C hub with ports | $20-40 | High | Medium |
| Keyboard with trackpad | $25-40 | High | Very high |
| Mouse only (on-screen keyboard) | $10-15 | Low | Very high |
Pro tip: If you travel a lot, invest in a folding Bluetooth keyboard. It fits in a wallet and completely transforms the Android-as-PC experience.
FAQ: Frequently asked questions
Does desktop mode work with any HDMI cable?
No. You need a USB-C to HDMI adapter compatible with DisplayPort Alt Mode. A regular HDMI cable won’t work because your phone has no HDMI port.
Can I use my phone while the desktop shows on the monitor?
Yes. With Samsung DeX and Motorola Ready For, your phone works independently. You can take calls and use apps on the phone while the desktop is on the monitor.
Can you game in desktop mode?
Yes, but the experience varies. Games optimized for touch screens look awkward with a mouse. Games that support gamepads work great with a Bluetooth controller.
Is it actually useful for work or just a novelty?
For basic tasks (email, browsing, documents, presentations) it works surprisingly well. For heavy work (video editing, programming, design) it’s still limited compared to a real laptop.
Conclusión
How to enable desktop mode on Android with an HDMI cable is simpler than it seems, and in 2026 the experience is genuinely usable. Samsung DeX remains the best option, Motorola Ready For is a solid alternative, and generic options work for basics. If you travel frequently or want a minimalist setup, your phone can be your PC. Try it with a $15 adapter and you’ll be surprised.
