Pro Agent display and color
- 4:4:4 Uncompromised color accuracy.Full-RGB color without sub-sampling blur. Crisp edges on fine lineart and sub-pixel text, which matters in Photoshop, Illustrator, and color grading.
- 10-bit HDR Wide color gamut.Deep blacks, vivid contrast, and true dynamic range. Grade HDR in DaVinci Resolve or view Blender renders the way they look at the host.
- High FPS Local-like canvas response.Frame pacing with minimal encoder latency, so pen strokes and 3D viewport navigation stay smooth.
- Stylus sync Direct dongle integration.The streaming agent keeps the video in step with the ESP32-S3 dongle, so pressure and tilt meet the canvas without a lag.
Engineered for artists and VFX creators
Whether you are color grading in DaVinci Resolve, sculpting high-poly meshes in ZBrush, or painting fine details in Photoshop, the USBridge Pro Agent keeps the color and the pen input fluid in real time.
Connect a remote Wacom to macOS without a driver conflict.The ESP32 dongle emulates USB in hardware, so the Mac treats the remote tablet like one plugged in directly.
Key capabilities
- Native driver Wacom Center sees the tablet.Express Keys, pressure curves, and pen shortcuts are set the same way as on a tablet plugged into the Mac.
- USB emulation No kernel extension.The ESP32 dongle presents the tablet's own USB identity. macOS registers a real device on that port.
- Full input Pressure, tilt, and Express Keys.Pen pressure, tilt, the eraser, and the tablet's Express Keys come through to the official driver.
