Turn an Android Tablet Into a Windows 11 Drawing Pad With Pressure Sensitivity

How-To Geek writer Joe Fedewa recently highlighted how quickly an idle Android tablet can be press-ganged into desktop illustration duty using a suite of free applications called Pad from independent software studio Codonic. In his testing with a OnePlus Pad 2 and a Stylo 2 active pen connected to a Mac running GNU Image Manipulation Program (GIMP), Fedewa reported going from download to drawing in under five minutes, observing wireless latency figures as low as 6 milliseconds on the app's built-in counter.

For Windows 11 users, DIY hardware recyclers, and occasional digital artists who cannot justify buying a dedicated Wacom peripheral that might gather dust eleven months out of the year, the setup offers an intriguing workflow. However, turning a consumer tablet into a desktop pen display on Windows 11 comes with specific architectural requirements, API quirks, and setup caveats that are worth understanding before you dig that old charger out of the closet.

Why Ordinary Screen Mirroring Fails the Artist​

Anyone who has ever tried to sketch in Photoshop or Krita over a standard remote desktop or basic screen-mirroring tool knows the frustration immediately. Conventional screen-sharing software treats your finger or stylus as a dumb mouse cursor. You touch the glass, and the host PC registers a simple left-click at maximum pressure. There is no nuance, no tapering line weight, and no shading control.

To replicate a dedicated graphics tablet, the software bridge has to preserve the return path of the digitizer data. According to Codonic's technical documentation, Pad operates as a two-part system: a client app on the mobile device (PadDroid for Android 9 or later, or PadPad for iPadOS 18 or later) and a host utility on the computer (PadWin beta for Windows 11, or PadMac for Apple-silicon Macs running macOS 15 or later).

Instead of translating stylus touches into generic mouse clicks, the host injects real system-level tablet events. On Windows 11, PadWin uses Windows' synthetic pointer API (Windows Ink) to pass pressure, tilt, azimuth, barrel roll, hover, and eraser states directly to tablet-aware desktop software—provided your physical tablet and stylus actually report those metrics.

Section Summary:

• Standard mirroring vs. Pen injection: Basic remote tools only send mouse coordinates; Pad synthesizes native OS tablet events.
• Hardware prerequisite: Software cannot invent hardware sensors. To get pressure sensitivity, your tablet must have an active digitizer and compatible pen (such as a OnePlus Pad 2 with Stylo 2, a Samsung Galaxy Tab with an S Pen, or an iPad with an Apple Pencil).
• Touch fallback: Standard capacitive touch on an Android phone or non-stylus tablet still works for quick PDF signatures or whiteboard markups, though without pressure dynamics.

Inside the Windows 11 Beta: Architecture and Dependencies​

While How-To Geek's hands-on test focused on a Mac host, Windows 11 users get broad hardware coverage with a few beta-stage rough edges. According to Codonic's setup documentation, the PadWin host (currently at beta 1.2.1) runs natively across x64 (Intel and AMD) and ARM64 (Snapdragon and other Windows on ARM) processors.

Because PadWin is still in beta, it operates differently than a polished Microsoft Store release. Here is what happens under the hood on a Windows 11 machine:

When you run the standard PadWin installer on Windows 11, it installs into your user profile without requiring administrator elevation. It automatically checks for two external dependencies—Microsoft's .NET 9 Desktop Runtime and the FFmpeg video encoder from gyan.dev—and fetches them if they are missing. For users who prefer not to run installers, Codonic also provides portable ZIP archives for both x64 and ARM64, which require you to manually install the.NET 9 runtime and drop ffmpeg.exe into the same directory as PadWin.exe.

A word of caution from a security perspective: Codonic notes in its documentation that the PadWin beta executable is not yet code-signed, meaning Windows Defender SmartScreen will flag it and require clicking More info -> Run anyway to proceed. As any veteran systems administrator will tell you, bypassing SmartScreen should only be done when you have obtained the installer directly from the developer's verified source and understand the risk of running unsigned beta code.

Step-by-Step: Setting Up Your Tablet on Windows 11​

If you have an Android tablet running Android 9 or newer and a Windows 11 PC, setting up the workflow takes only a few minutes when your network cooperates.

1. Install the Windows Host: Download and run the PadWin beta installer (or extract the portable build along with .NET 9 Desktop Runtime and ffmpeg.exe).
2. Configure the Windows Firewall: On first launch, Windows Defender Firewall will prompt you for network permissions. Allow PadWin access on Private networks so your tablet can discover the PC over your home Wi-Fi. Leave Public networks unchecked unless you have a specific, secured reason.
3. Optional Security Pairing: By default, PadWin allows any client on your local subnet to connect. If you share a household network, click the PadWin icon in the Windows system tray and enable Require pairing code, which enforces a six-digit verification handshake.
4. Install the Client: Download PadDroid from Google Play onto your Android tablet and grant local-network permissions if prompted.
5. Connect via Wi-Fi or USB-C: Launch PadWin on the PC first, then open PadDroid on the tablet. Over Wi-Fi, the PC should appear automatically. Prefer a wired connection to eliminate wireless jitter and keep the tablet charged? Plug the Android tablet into the PC via USB-C and choose Trust on the tablet; PadWin uses a bundled copy of Android Debug Bridge (adb) to tunnel the traffic over the cable.
6. Choose Your Capture Mode: Rather than cramming an entire 4K desktop monitor onto an 11-inch tablet screen, use Pad's capture selector to stream either a single application window (which automatically scales to fit the tablet's aspect ratio) or use Select Area to draw a bounding box strictly around your software's canvas.

Keeping only the canvas on the tablet while leaving complex layer palettes and toolbars on your primary PC monitor mimics the feel of a dedicated pen display without cluttering your drawing surface. Meanwhile, the tablet displays a customizable sidebar featuring Windows-specific modifier keys (Ctrl, Alt, Shift, Win) and quick shortcuts like Ctrl+Z for undo.

Section Summary:

• Prerequisites: Ensure .NET 9 Desktop Runtime and ffmpeg.exe are present, and allow PadWin through the private network firewall.
• Wired vs. Wireless: Local Wi-Fi is convenient, but USB-C via adb avoids router congestion and powers the tablet.
• Canvas optimization: Streaming only the canvas region maximizes drawing space while keeping menus on your main monitor.

Crucial Application Tweaks: Krita, GIMP, and Photoshop​

Getting the video stream onto the tablet and the pen strokes back to Windows 11 is only half the battle. Desktop art programs have decades of legacy tablet code, and they do not all listen to the same Windows input APIs by default.

• The Krita WinTab Trap: If you open Krita on Windows 11 and find that your stylus only draws a single stationary dot or refuses to register pressure, the culprit is an API mismatch. Krita defaults to the older Wacom WinTab API, whereas PadWin injects strokes via Windows Ink. According to Codonic's setup guide (verified in Krita 6.0.4 on Windows 11), you must go to Settings -> Configure Krita -> Tablet settings, switch the radio button to Windows 8+ Pointer Input (Windows Ink), click OK, and restart Krita.
• GIMP Dynamics: In the GNU Image Manipulation Program, pressure sensitivity is often ignored until explicitly enabled for your tool or brush. As Fedewa noted in his walkthrough, toggling on Enable dynamics in the brush tool options allows GIMP to respond to incoming pressure curves.
• Adobe Photoshop: Because modern versions of Photoshop on Windows listen to Windows Ink out of the box, pressure and tilt data generally work without changing internal API preferences.

Troubleshooting Common Failure Points​

Even simple tools hit snags when bridging two different operating systems over a local network. Based on Codonic's documentation, here are the fixes for the most common failure states on Windows:

• The tablet connects, but the screen is black or missing: PadWin cannot find ffmpeg.exe. If you used the portable ZIP or a strict antivirus quarantined the encoder, ensure ffmpeg.exe is sitting directly next to PadWin.exe or inside an ffmpeg subfolder.
• The PC never appears in PadDroid: First, verify that your Windows network profile is set to Private and the firewall rule for PadWin is active. Second, check your Wi-Fi environment. Corporate, school, hotel, and router "Guest" networks usually enable client isolation, which blocks devices from talking directly to one another even when they share the same Wi-Fi name. Switch to a standard home SSID or plug in a USB-C cable.
• Cursor lands on the wrong monitor: Multi-monitor setups where a secondary display is positioned logically to the left of or above the primary monitor previously caused coordinate mapping offsets on Windows. Codonic reports fixing this bug in PadWin 1.1.0, so ensure you are running the current beta build (1.2.1 or newer).

The Broader Picture: Software Bridges vs. Dedicated Hardware​

How does a repurposed Android tablet stack up against established players? The concept of turning a tablet into a secondary pen display is well-tested territory, populated by commercial veterans like Astropad Studio, Duet Display, EasyCanvas, and VirtualTablet, alongside native OS features like Samsung's Second Screen or Apple's Sidecar. Dedicated hardware manufacturers are also blurring the lines from the other direction, with devices like the Android-powered Wacom MovinkPad 11 offering standalone portable sketching that can also link to a PC.

Where a lightweight, free tool like Pad carves out its niche is friction reduction. Commercial alternatives frequently require subscriptions, user accounts, or heavy virtual display drivers that hook deep into the Windows kernel. According to Codonic, Pad requires no user account, collects no personal data, and sends video and stylus traffic peer-to-peer across your local link without touching a cloud relay server.

Will a wireless tablet running through a software H.264 encoder on Windows 11 replace a hardwired Wacom Cintiq for a professional studio illustrator working eight hours a day? Probably not. Dedicated pen displays offer etched anti-glare glass, zero network jitter, and deeply entrenched WinTab driver support. Furthermore, while Fedewa saw 6ms latency under his specific Mac and router conditions, wireless latency on Windows will always remain at the mercy of your local Wi-Fi congestion, router placement, and PC encoding load.

Still, for students marking up lecture PDFs, engineers sketching out quick architecture diagrams on a whiteboard, or hobbyist artists who want to experiment with Krita or Blender sculpting without spending hundreds of dollars on new hardware, breathing new life into an old Android tablet is one of the smartest zero-dollar upgrades you can make. Just remember to switch Krita over to Windows Ink before you blame the pen.
