My projector (Acer H6520BD) has an instant off setting. When it is turned on the projector turns off instantly when I press power off. If the instant off setting is turned off, the projector remains active for a few dozens of seconds. During this time the lamp is glowing dimly and I hear the fan going.
Neither the manual nor the software offer any disadvantages or advantages of either mode.
From what I can observe, instant off has the advantage of being instantly off, while non-instant off has no advantages. Yet instant off is turned off by default. It seems there must be a reason why they choose this apparently inferior mode as defailt.
So my question is: are there any hidden disadvantages to instant off? Is it maybe bad for the lamp to be turned off instantly?
