For detailed hardware-related instructions, visit the Philips Dropbox documentation. Click “Models” in the bottom-left menu to select your display.

To ensure compatibility, update your firmware by following the steps in the Philips instructions manual:

Access the instructions through the Philips Dropbox by selecting “Models”, finding your display, and opening the manual (use right-click to open in a new tab if needed).
