"Option 2: Smartphone + USB-C dock + portable monitor
This modular approach is more flexible, allowing you to choose your preferred screen and docking hardware.
Setup: Connect your smartphone to a USB-C dock, which is then connected to a portable monitor. Many compact docking stations will be sufficient for this.
Portable monitor: Brands like Arzopa, KYY, and Lenovo offer a variety of portable monitors that are lightweight and have USB-C video input.
Docking station: A simple USB-C hub is all you need to add connections for power and a keyboard or mouse. For more demanding use, a higher-end dock will provide additional ports and more powerful charging.
Benefits: This offers more portability and a wider choice of screens. You can use the portable monitor with other devices, such as a laptop or game console.
Key features to look for
No matter which option you choose, your phone must support a desktop mode feature.
Samsung DeX: A software platform on flagship Samsung phones that provides a full desktop-like interface on an external monitor with resizable windows and multi-tasking support.
Motorola Smart Connect: A desktop and multimedia platform for compatible Motorola smartphones.
Android Desktop Mode: A native, though often experimental, feature in Android (version 10 or later) that can be enabled in the developer settings.
Limitations to consider
Performance: The speed of your desktop experience will be limited by your phone's processor. It is suitable for light productivity tasks but is not a full PC replacement.
Compatibility: Not all Android phones support a full desktop mode. Check that your specific phone model works with a "ready for" feature like DeX or Smart Connect.
Wired vs. Wireless: A wired USB-C connection is generally more reliable for video output and charging than a wireless connection. Wireless setups may use Miracast and Bluetooth, which can introduce lag. "
