Q: What is the 3M™ Mobile Projector MP300?
A: The 3M Mobile Projector MP300 is a battery operated projector and can also project images from MHL and HDMI enabled smartphones, tablets, computers and DVD Players. Additional cables may be required.

Q: What is MHL?
A: This is a new digital video and audio interface for smartphones, and other portable devices as well as TVs. MHL allows your device to send video and audio to the projector over a single cable while the projector charges your device. Additionally, you can control some or all of the features on the portable device using the projector's remote control.

Q: What is the difference between MHL™ and HDMI®?
A: Even though a display has an HDMI input, does not mean it is MHL enabled. Most MHL enabled displays such as the 3M Mobile Projector MP300 are compatible with both MHL and HDMI enabled devices. In addition to playing back video and audio from a MHL enabled device, a MHL enabled display can charge and control the device. For a list of MHL enabled devices, please refer to

Battery and Charging

Q: How long does it take to charge the battery?

The Power Adapter and Charging the Battery

I do not see where to insert the outlet clip into the power adapter.

  • There is a blank clip inserted into the power adapter when it is shipped. Remove the blank clip which covers the power adapter contacts. Now install an outlet clip.
Image showing how to remove the blank clip which covers the power adapter contacts.

I do not see an amber light when I plug the power adapter into the projector.

  • Make sure the power outlet is working.
  • Make sure the connector from the power adapter is plugged into the "DC In" on the projector and not the headphone jack.
  • When fully charged, the LED indicator will flash green.
Installing the HDMI or MHL cable into the Projector

The HDMI or MHL cable will not insert into the projector.

  • There may be a dust cap on the end of the connector. Remove it before inserting connector into the projector.

The cover does not close properly.

  • There is tab on the bottom corner of the cover. Make sure the tab inserts into the groove on the projector and the rest of the cover snaps into place.
Turning the Projector On or Off

The projector will not turn on.

  • The battery is not charged. Plug the power adapter into the projector and try again.

The projector button panel is on but the projector is not projecting an image.

  • The video source (such as the DVD Player) is outputting a black image. First, try disconnecting the HDMI video cable. Do you see the 3M™ logo screen? If not, try turning off the projector and turning it on again. If you still do not see a 3M Logo screen while the status indicator is green, contact 3M for additional support.
  • The Lamp is off. Press the Lamp ON/Off button on the remote control.

The remote control will not turn on the projector.

Setting Up the Projector

The projector falls over when I place it on its rear cover.

The image is tinted or discolored.

  • The wall or surface you're projecting onto is colored. Try projecting onto a white wall or surface.
  • The lens may be dirty. Use a dry cotton swab to clean it off.
Focusing the Image

The image is blurry.

  • Use the focus wheel on the side of the projector (next to the lens) to sharpen the image.
  • Reduce the input resolution. The native resolution of projector is 480p. Therefore, resolutions greater that 720p may appear blurry.
  • If you are closer to the projected image than the projector, you might be seeing the individual pixels that make up the image. Reduce the size of the image or move away from the image.

The image is too dim.

  • Reduce the image size and/ or decrease (darken) the room lighting.

The image seems bright enough but there are no details in the dark shadows.

  • Open the projector menu and increase brightness setting and then decrease the contrast slightly.

The image seems bright enough but there are no details in the highlights.
