Projector time
I've had my Samsung 2233RZ for nearly a week now, awesome. But i want more, i want a projector. Ghosting is already annoying me..

I have been a TV guy for years now and have never even considered PJ's for Home Theater and do not know much about them , what technology is best or anything like that. (although i do probably still know more than average joe).

I have several questions;

So far, i'm basically decided on the Acer H5360, because there isn't much choice.

My most important question is, is there anyway i can figure out what placement in the room would result in what size dimensions image would be projected, and where it would be projected ?
And what screen size is the limit for a 720p projector before the IQ starts to suck ?
Is there a cheaper way than buying a projection screen that will offer a decent picture still ? (Painting the wall white :"> ...)

I know acer offer bulb life times, but i have no idea whether they're reliable at not. So how long should i expect out of the bulb for the acer H5360 and how much are replacements ?


Thanks for help in advanced.

This is the official Acer calculator for their currently available models. Just choose the Acer H5360!

In case the link is not working, just "google" for "Acer calculator" and you should be fine!

Im doing a stress test on the Acer H5360, Im at 1700 hours, no problem so far, brightness might be 1/3 lower than what it was until about 800hours.
First and foremost:
You need a screen thats not matte white.
That reflects that all over the room (on the walls) , you loose contrast and brightness, at least lights everything evenly across the room.

You'd better get a high gain, screen, thats more reflective to start with (2x , 2.5x the brightness), and better focused, so most of the light ends up in your eyes. Plus rejets ambient lightning better because of this, (less light on walls), so contrast is better. Even cheap silver spraycans going to give you this advantage over plain mattewhite screen. But you have ot be careful.

If you want to upgrade to 2 projectors with imax style polarizer glasses, you also need this kind of screen plus its "polarization preserving" "3d ready" capabilities. Paint like that costs 160usd, with gain 4x, its called something 3d HD.

There are tricks to play with the intense brightness if you dont need it in 2d, just put darkening a foil in front of pj, or , apply a diy iris. Latter is better because you actually get better blacks.

Something not a lot of people know, but be aware of lens throw specs. Some projectors need a 20 foot room to make a good wall sized projection, while many "short-throw" lens projectors can do the same in 5 foot. I really suggest whatever you get be short-throw as to take full advantage of a large a projection as you want with little fuss.
