NEC M311X Setup and Menu
The NEC M311X was easy to setup and start using. It features nearly instant on (and off), so you quickly have an image to adjust to your screen. Automatic keystone adjustment is enabled by default, but you’ll likely want to turn it off so you can optimize the image before applying any correction (if needed). The M311X has just two height adjustment feet (one in the front center and the other in the left rear) that help to level the projector if table-mounted. We would prefer two rear adjustable feet, but the two feet provided are still better than the usual single center foot. The 1.7X zoom also helps to properly position the projector. Once you get the positioning close, you can use the automatic keystone correction (or adjust it manually) to square the image on your screen. While we usually don’t recommend using any keystone correction due to image distortion, small to moderate amounts of correction have no visible effect on the M311X.
Once setup is complete, the user brings up the menu, where the desired image mode can be selected. There are seven main preprogrammed modes (High-Bright, Presentation, Video, Movie, Graphic, sRGB and DICOM SIM). There is also a Wall Color Correction setting that can be set to one of nine colors. With any mode, you can make the usual adjustments for Contrast, Brightness and Sharpness. Adjustments to Color and Tint are not available with an HDMI or USB input. The M311X also includes a range of selectable gamma and color temperatures, as well as RGB grayscale adjustment capability.
