Using the NEC M300W Data Video Projector

Getting Started

Connecting power and video cables

Plug the black power cord into the AC IN socket in the back of the projector. Plug the other end of the cord into the wall or an extension cord.

Connect the grey VGA (video) cable to the VGA out port on the back of the computer or laptop. Connect the other end of the VGA cable to the port on the projector labeled Computer 1 IN.

Powering on the projector

Computer should be OFF.Slide the lens cap over and push the white (I/O) button on the top of the unit to turn the projector ON.

A blue screen should be projected after the lamp warms up. This may take a minute or so.Turn computer ON.

Configuring the computer to connect to the projector

For Macintosh users:

Click on the Apple icon in the upper left corner of the screen. In the menu that appears, click on the System Preferences item.

In System Preferences, under the Hardware section, click on the Displays icon:

A window labeled Color LCD will open, containing the built-in display settings.

Open the application containing your presentation.

If you want to change the size of the image displayed on the projector screen, you can lower the resolution. To do this (from the Color LCD window), click on the Display tab. In the Resolutions box, click on the resolution desired (note: 1280 x 800 is the default).

If the laptop's image does not display on the projector screen, click on the Arrangement tab in the Color LCD screen. You'll see a Mirror Displays check box in the lower left corner of the Arrangement window. Click in it to checkmark it. The image displayed by the projector should now be the same as the image displayed on the Mac's screen.

If you still cannot get an image to display on the screen, you can try lowering the refresh rate to 60 Hz, accessed through the Display tab (above).

In the Mac's Menu bar, click on System Preferences and then Quit System Preferences.  You can then proceed with your presentation.

For Windows users (Windows XP laptops and newer):

Once started up, the desktop image should now automatically display on both the laptop screen and the projection screen.

Open the application containing your presentation.

If the image appears only on the laptop screen but not the projection screen, you may have to press certain function (Fn) key combinations to set the laptop to display the image on both. On Dell laptops press and hold (for 2-3 seconds) the Fn key (on bottom of keyboard) together with the F8 key (on top) one time. On HP desktops, typically it is the Fn and the F4 key.  If the image doesn't display on both screens, press this key combination a second time. If it still doesn't display, press a third time. Toggling through these three sequences should eventually get both screens to display the image.

If the laptop's image still won't appear on both the laptop and projector screen, try adjusting the laptop's resolution: Via the Start menu, find the Control Panel. Double-click the Display icon, then click the Settings tab. Set the laptop's resolution to 1280x800. Press the Apply button both times to make the changes. The laptop image should now appear on the projector screen.

Adjusting the projector image

Image height:

To raise the image to a different height, adjust the height of the front legs. Press up on the release clips above the projector legs to extend the legs while tilting the projector up to the desired height . You can also fine-tune the height by screwing the legs in and out.


If the image is too small or large, adjust this manually using the lever labeled ZOOM on top front of the projector.


If the image is out-of-focus, adjust this manually using the ring labeled FOCUS on top front of the projector.


The keystone correction is set to on as a default on this projector.

Powering off the projector

When finished, close the presentation and shut down the laptop.

Hold down the white O/I button for two seconds. It will ask “Are you Sure?” Press the button again. After a few more seconds the screen will go black, but the fan will still be running.

DO NOT UNPLUG OR TURN OFF THE PROJECTOR until the fan stops running. The bulb will be damaged if it is not given adequate time to cool down.

Once the fan stops running, unplug the projector.
