Why do I get a "No Signal" error when I connect my PM161Q monitor?
The Acer PM161Q monitor is only compatible with devices that support USB 3.1 video output. When your PM161Q is connected to a USB-C port that supports video output, it should automatically detect and show the image from the connected device.
If your monitor is not displaying a signal, check to make sure it is connected to a device that supports outputting video via USB-C. These ports are often labeled using the icons below. If you are unsure if your device supports video out via the USB 3.1 port, please contact your device manufacturer.
If you are connecting to a USB-C port that supports video output and are still unable to get your monitor to connect, please contact Acer support .
