For 3D MMN unsuitable because you paying extra hardware required, who looks equal a device for the 3D mode, a projector should buy with "3D over HDMI", what you eg ACER 150, - has to put more on it + shutter glasses
The only drawback to the projector is the volume in operation and in standby mode (an audible noise / low whistle), but power strip with switch, saves definitely current :-)
