Windows settings

Open it from the tray menu › Settings…. The window has no taskbar button; closing it hides it, and Settings… brings it back. Settings that need a restart show a Restart PixelBridge to apply banner that names them.

Applies says when a change takes effect: on the next connection, after restarting PixelBridge, at your next sign-in, or at once.

Startup

Setting	Default	Applies	What it does
Start PixelBridge when I sign in	On (set by setup)	Sign-in	Starts PixelBridge with Windows, for your Windows account. You can also turn it off in Task Manager › Startup apps.

Display

Setting	Default	Applies	What it does
Match the tablet’s resolution	On	Next connection	Sizes the PixelBridge display to the device’s screen
Place the display beside your main screen	On	Next connection	Positions the display so the pointer crosses into it from the edge you’d expect

Resolution, frame rate, bitrate and codec are not settings here: the connected device announces its own screen and the PC follows. See Resolution and refresh rate.

Pen

Setting	Default	Applies	What it does
Pen input	On	Next connection	The master switch. Off, the device’s pen does nothing on this PC.
High-precision digitizer	On	Next connection	A virtual pen with sub-pixel positioning and pressure. Falls back on its own if it can’t be created.
Wintab for legacy creative apps	On	Next connection	Lets older art software read pen pressure
Compensate pen geometry when mirroring	On	Next connection	Keeps the ink under the pen tip in Duplicate mode
Macro palette	On	Next connection	Accepts shortcuts from the app’s shortcut palette
Pen in Krita and other Qt apps	On	At once	Lets Krita and other Qt apps read pressure from PixelBridge while a device is connected. Applies to every account on this PC.

Connection

Setting	Default	Applies	What it does
Allow connections over Wi-Fi	Off	Restart	Lets devices connect over your network as well as the cable
Wi-Fi only — don’t serve the cable	Off	Restart	Stops USB entirely, for when another tool needs the USB connection. Turning it on also turns Wi-Fi on.
iPhone and iPad over USB	Off	Restart	Not used yet: there is no iPhone or iPad app. Leave it off.
Wi-Fi port	27185	Restart	The network port. Change it only if another program uses it; Windows asks once about the firewall (click Allow).

Pairing

Setting	Default	Applies	What it does
Ask before a new device connects	Off	Restart	A first-time device shows a six-digit code and waits for you to allow it here. Approved devices reconnect on their own.
Refuse devices that haven’t paired	Off	Restart	Drops unpaired devices without asking
Paired devices			Each paired device, with Rename and Forget

Advanced

Setting	Default	Applies	What it does
Keep this PC awake while serving	On	Next connection	Stops the PC sleeping mid-session
Keep this PC’s screen awake too	Off	Next connection	Also stops the screen blanking and locking. Leave it off on a PC you walk away from.
Tell me when an update is out	On	Restart	Checks once a day for a new version. Nothing about you or this PC is sent.
Pin input to one adapter (Diagnostic)	Empty	Next connection	For troubleshooting only. Leave it empty.

Quick toggles in the tray

Tray menu › Quick toggles holds a few of the same settings under shorter names, applied on the next connection: Pen input · Pen: HID digitizer (sub-pixel) · Pen: Wintab for legacy apps · Macro palette · Match the client’s resolution · Keep this PC awake while serving · Keep the PC’s screen awake too. Open settings file… opens the settings as a text file.

The settings file

Settings are saved per Windows user in %LOCALAPPDATA%\PixelBridgeHost\settings.json. If the file is damaged, PixelBridge ignores it and uses the defaults. If the Microsoft Edge WebView2 runtime is missing, Settings… opens this file instead of the window; running setup again installs WebView2.
