I have a Sharp LCD front projection screen:

I was wondering if it would be o.k. to use a Playstation on this type
of projector. I know that some bulbs in these projectors can be
damaged by such video games. I'm not looking for 'burn-in' - but
rather if the Playstation itself will damage the bulb in other ways.

Thanks.

You should be able to use it without problems not concerning burn-in.
The LCD Projector doesn't know what video signal is coming in whether
it be from a laptop doing a presentation, or a Playstation. The main
risk comes from burn-in due to prolonged static images being displayed
(like the health bar in a game, although I've seen the Microsoft Start
Menu burned into many a LCD projector). So I took the time to write
Sharp's support team and received this response:

---
The game system could be connected to the video input. It is not
recommend for long use due to it could cause burn in.

Please advise if you have any further questions.

Awesome, thanks!

Google won't let me become a researcher, so I can't really devote lots
and lots of time to answering your query.

The fact is that burn in is really an issue in few instances:

1. Archaic TV Screens, with crap phosphors.  Not an issue for you or
anyone who's bought a new TV in the past 15 years.

2. Non-DLP based rear-projection TV sets will burn in.

3. Old LCDs, as far as I know, there's no specific cut off date, I
would hazard a guess that anything beyond first generation active
matrix-TFTs is probably just fine.

4. Many, many plasma sets.

That projector is hella old, I would guess that it would suffer from
burn in.  *shrugs*

Take care,
