This article is intended for users who are seeing a "No Signal" message on screen or only the Miroir logo screen when connecting their source device to a Miroir projector that does not have an operating system built in (all models except M200A and M300A).
Most Common Issues
The "No Signal" message (or some models with just display the Miroir Logo screen) indicates that the projector is not receiving an input signal from your source device. These are the most common reasons you may be seeing the "No Signal" message:
- The projector and the source device are not connected correctly.
- Check that the cables and adapters are firming plugged in.
- Check that you are using the proper cable and/or adapter to connect your source device to the projector. If you are not sure if you are connected correctly, check the What do I need to connect section of support articles. You can also check with your device's manufacturer.
- Important: USB ports labeled with USB 5V Out cannot be used for projecting. These ports are only able to provide USB power out for recharging smartphones or for powering streaming sticks that require power.
- If you are connecting a Miroir M220 via USB-C:
- Check that you are using the USB-C cable that came with the projector. The cable has "USB-C Video Cable" printed on one end. Not all USB-C cables will support video.
- Check that you have the USB-C cable plugged into the USB-C port on the projector that is labeled USB-C Video and not the USB-C Charge port.
- The source device connected to the projector is not outputting a video signal, or is outputting a video signal that is incompatible.
- Some devices, such as a computer or laptop, must have a secondary display setting setup in order to output a signal to the projector. Check the display settings on your computer or laptop to ensure a multiple display option (such as "duplicate these displays") is selected.
- Check the resolution settings on your source device and select a 1080p or 720p resolution.
- If you are connecting to a gaming console, you may need to reset your display settings. If you are unsure how to do this, consult your product manual or contact your console manufacturer for additional information.

- The adapter or cables being used are not functioning properly.
- To test this, you can try connecting your source device to another display (such as a TV) using the same cables and adapters. If you are still unable to connect, you may not be using the correct cables or adapters, or they not be functioning correctly.
- If you are connecting an iPhone or iPad, be sure to check that you are using an authentic Apple Digital AV adapter. Third-party adapters may not function properly.
- The input mode selection on the projector is incorrect (only applies to M200A and M300A model projectors).
- Check that HDMI input is selected by pressing the input button on your remote  > HDMI > [OK] on your remote.
