simple stupid question: If I keep my projector (dlp acer pd523) on, but would display a black image ...would the lamp life AND dlp chip life decrease?

.

.

follow up question: I heard once you turn a projector on, it will decrease the lamp life 8hours, not matter if it is actually only on for say 2 hours....

.

.

thanks for all insights and comments!

I don't know much about projectors, but I would assume that as long as the lamp is on it would be decreasing the lamp life.

If it's using newer LED lamps instead of bulbs, just keep in mind LED lights are rated for thousands of hours.  But if you plan to put it to "sleep" for hours, I think it's better to just turn it off and save on the electrical bill and overheating of the device.  However if you need to blacken the projection for a short moment (e.g. such as during a presentation and you want the audience to focus on you on the stage instead of the screen in the background), putting the projector to "sleep" is better than powering it down as it may take a brief while for it to turn back on when you need it.

 

Basically just use your judgement.

...if you need to blacken the projection for a short moment ...

Open MS paint.  Set the image to your resolution.  Fill bucket black.  Click full screen.  Profit :)
