Public beta · free

One PC.
Every screen you own.

WDX turns your Android phone or tablet into a second screen, a webcam, a microphone and speakers for your Windows PC — over USB, Wi-Fi or Wi-Fi Direct.

01Second screen

A real second screen.

WDX installs its own display driver, so Windows sees your tablet as a genuine monitor — not a video of your desktop.

Drag anything across.

Windows, the taskbar, full-screen apps and games move over the same way they would to any monitor.

Sharp at native resolution.

WDX runs at your tablet's own resolution and refresh rate, so text stays crisp instead of stretched.

02Display alignment

Real size, not pixel count.

A 3K tablet has more pixels than a 2K monitor, so Windows treats it as the bigger screen. Turn on Display alignment and WDX uses the real size of each screen instead.

Windows lines up pixels.

Windows keeps the same pixel row when the cursor crosses an edge. On screens with different pixel densities, it lands higher or lower than where you were heading.

WDX goes straight.

Lined up in millimetres, the cursor moves between a 24″ 2K monitor and a 12.4″ 3K tablet at exactly the same height, both ways.

Turn it. Windows turns too.

Hold the tablet upright and the virtual display switches to portrait on its own.

Extend or mirror.

Use it as an extra screen, or show exactly what is on your main display — one tap to switch.

Your tablet is the webcam.

Set it right below your screen. WDX adds a real camera to Windows 11 — pick “WDX” in your meeting or streaming app.

05Audio & devices

Your PC's sound, on the tablet.

Send Windows audio to the tablet's speakers, or to the headphones plugged into it.

And its mic, too.

Talk to the tablet and Windows hears a clear microphone, with background noise filtered out.

Or hand them to your phone.

Webcam and mic can come from another device. Pick up your phone to walk around, or hold it close to what you are filming.

06Connect

Plug in.

Over a USB cable WDX gets its lowest latency, with a ping under 2 ms. Plug-and-play USB is on the way: plug in and it connects — no developer mode, no USB debugging.

USB AOA · in development

Or go wireless.

On the same Wi-Fi, your PC and tablet find each other and connect in seconds. With the router across the room, ping sits around 10–15 ms.

Then it gets faster.

In the background WDX sets up Wi-Fi Direct — a private link with no router — and moves the stream over without interrupting the picture. Your tablet stays on its Wi-Fi. Ping drops to 3–5 ms.

Questions

Before you download.

Is WDX free?

Yes — every feature is free during the beta. We'll announce pricing before the beta ends.

What works in the beta?

Second screen, webcam, PC sound on the tablet, and every connection. Using your phone as the PC microphone and plug-and-play USB need Microsoft-signed drivers: while we complete the legal procedures they are locked in the standard version, or you can use them now with the full version, which needs Windows test mode. Details on the changelog.

How much delay is there?

Typically 20–50 ms end-to-end compared with a monitor plugged into the same PC — close enough to feel native for desktop work, browsing and video. For fast competitive games a wired monitor is still best.

Does my screen go over the internet?

No. Video, camera and audio go straight between your devices over the cable or your local network, encrypted. There is no WDX cloud in the middle.

Which Android devices work?

Phones and tablets on Android 8.0 or newer. Tablets with a high-refresh screen give the best experience.

What does my PC need?

Windows 11 (64-bit) with an NVIDIA, AMD or Intel graphics card that can encode video in hardware.

Mac or iPhone?

Not yet. WDX supports Windows + Android for now.

Free during beta.

Install the Windows host, then get the Android app.
