Why the projector light reflection is very high ? how to reduce it ?!
Hi , I have an H5360 PJ and when I play in a very dark room , the projectors reflection light shines up the room , I can see every thing in my room like the light are on , my room size is 4mX 4m ??? any suggestion?!!

Matte white screen produces ambient lightning because it spreads the useful light across the room. And btw at 120hz theres not much useful light with H5360 at all:
It only should produce much ambient lightning at 60hz , once at 120hz it drops below 750 lumen.
BTW, use dark courtains , or make it bright enough for day use ;)
Spraypainted screen gives more focused light. Also curved screen does.

Tritosine, it's the not spraypaint that causes the screen to reflect light differently, it's the characteristics of the paint you use.
Hi, Planet-earth
The culprit of this behavior is the material of the screen you use.
A traditional screen (white matte material, or other cheap solutions like using the wall) reflects light in all directions, towards you wherever you stand in the room and also the walls, thje floor and the ceiling.
If you want to focus the light differently (more towards you and less towards the sides) you have to use a screen with different light reflection properties so that the screen acts in a way that looks more like a mirror than a diffusing surface.
The way Tritosine recommends you is the DIY approach, use a cheap screen material and add a coating of silvery-like paint on top of it. It's the cheapest way of doing it but requires you to apply the paint coating yourself.
If you want to buy a finished product directly, there are many projection screen manufacturers that sell just what you are looking for but it's more expensive (prices vary greatly, some are cheap others are very expensive).
The characteristic of the screen you are looking for is called the screen gain. The higher the gain, the more the screen behaves like a mirror and the less light is bouncing to the sides. Most screen manufacturers provide charts that show how much light is reflected according to the angle of reflection.
There are advantages and drawbacks to using high gain screens, make sure you understand them before you decide to buy such a screen, you'll find plenty of litterature on the web and people arguing for and against it.
