Trouble Connecting: Laptop or Computer

Background

This article is intended for users who are having difficulty connecting a laptop or computer to their  Miroir projector. 

"No Signal" or No Image from Projector

For most models, you will see a "No Signal" message on screen or only the Miroir logo screen if the projector is not receiving an input signal. For Miroir projector models that have an operating system built in (M200A and M300A), you will see the home screen displayed if the projector is not receiving an input signal.

  • Check that the cables and adapters are firmly plugged in. 
  • Check that you are using the proper cable and/or adapter to connect your laptop or computer 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.
  • If you are attempting to connect a source device via VGA, double check that you are using a VGA to HDMI converter, not the more common HDMI to VGA adapter which will not convert your analog VGA signal to the Digital HDMI signal required by 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 laptop or computer are set to the "recommended" resolution or select a 1080p or 720p resolution.
  • Try connecting your laptop or computer 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.

Content Displayed Incorrectly

Desktop image or screen saver image projected

If you are seeing your desktop image or screen saver image displayed by your projector, you are connected correctly but you may need to adjust the display settings or drag content to the projector area.

  • If you are using an "Extend these displays" or an "Extend desktop" display setting you will need to drag content from your computer screen to the projected image.
  • Alternatively, if you are using a "Duplicate these displays" or "Video mirroring" display setting the projected image will be a mirror image of your computer screen.
  • Additional Information:

The image is jumping or shaking
