One of the features is the manual wall color correction that adapts the colors so that the presentation always looks bright, even if you project on a chalkboard or colored wall. To save costs on the lamps the VT670 has an eco mode that extends the lamp life up to 3.000 hrs and in addition an off timer to shut down the projector automatically after a certain time.
