i know everyone was trying to recreat either screen goo which to me is too expensive imho but has superb quality

however silver screen well no one i think would buy it eventho it's the *standard in quality* i assume

i just been thinking

and doing some research about well alot of safety jobs life fire fighters and stuff use coated reflective materials so i ran across this paint figured if no one had tried it they could run some test with this as a base

i read all 15 pages of where they did the test and stuff figured hey give this a shot since you got the body shop and access to a spray gun might get a result worthy of using i like how far you got into it the improvment i seen in some of the pictures of the special paint you mixed i will definaly want to recreate at my home

anyways we could brainstorm and you could tell us what you used and we could try to mix up diffrent combinations and use this too see if it has any worth

titanium dixoide
they are applying that to a roof to reduce the heat via reflectivity
just a thought titanium dioxide to the man hope this makes some sense

Here is a place that might help you with any questions, these guys have spent alot of time and $$ on the diy thing and have found great solutions for screen

flfkarnage,

I edited your post, to combine all 6 of them one after another, and some were duplicate post, Just trying to condence the thread.

very good i just got into a groove of finding diffrent things feel free i been having some friends test out some combinations

I was just reading the one link on avs forum about using HomeDepots Behr Silverscreen Flat on either a wall or 4x8 board. Sounds like most all of them had good luck for about $30's. I have to try that, when I get my pj done.

It was Behr "Silverscreen" (770E-2) mix using Ultra Pure White (UPW) flat latex

it was this POST if anyone wants to read it. (They get a bit ranty 3 - 4 pages in.)
Just a side note; after reading other forums and comparing them to this LL forum. I have to say the LL forum is much nicer.

While I concur that avsforum can be "less nicey" depending on the thread/section, the information one can derive from that site is invaluable and very incredibly informative. The real trick is to see through the sarcasm and pissing contests that inevitably flare up (these people are pretty passionate about what they're trying to accomplish- no different at LL)

Of course, it will be possible to be caught in the middle of a flame war, granted you ask the question with the wrong attitude, ie you've already made up your mind before you posted and anyone who differs in you're opinion is an idiot.

I saw this arguement when I was deciding on my pj when they were comparing it to the darling of 2004, the X1.

Back to diy screens, I still think the black levels of a LL pj are still challenged by the fact that it uses a low contrast lcd monitor, ie under 700:1

Try what I use, Lowe's Valspar Plank Gray interior flat latex. Some say there's a green tint to it, but I don't have that problem on my image. YMMV

Don't be fooled by specs, specs on paper do not always equate real world performance. I've seen commercial projectors that have 2000:1 contrast ratios that don't look nearly as good as many LL projectors I've seen with even 450:1 contrast ratios.

The projector I looked at in Sam's club stated, "Full on/Full off contrast ratio 2000:1". If we were to use that methodology in measuring our contrast ratio then we would get about the same results. Simply turn on your projector as bright as possible to measure your whites. Then completely turn off your projector to measure the blacks.

Simple.

I don't need to be fooled by specs since I have seen an LL projector 1st hand against my Sharp A10x.

I have also seen at length the following:

In a light controlled dedicated theater with a Stewart 106" screen

modded Infocus X1 (with diy iris and camera filters)
NEC HT1000
Sharp 10000
JVC D-ILA (best picture, IMHO)

I have also installed Infocus 4805 (In 2 theaters)
and demoed crt projectors at just about every high end store here in the bay area.

For resolution and throw constraints, I chose a XGA lcd pj, even though I could have at least got the X1 or even saved up for a used NEC.

From my eyes, this is what I notice. The LL black level contrast is no different than my Sharp A10x. Sure, perhaps the LL projector wasn't properly at optimal, but this is a real-world projector (SteveH), built by someone who wanted by his own projector. For what it does, its a fantastic unit. The colors were great, the smoothness was clearly better than my own unit. So in those regards th LL projector holds it own against the commercial brands.

The problem with LL, as with any other commercial lcd projector, and has been confirm time and time again on avs, is that black levels are still not as good as a dlp or bettr yet, a crt. Some units come close, but for the most part lcd still lags behind dlp. The design technology of the lcd is just not there yet. Perhaps in the next few years we will see advances from lcd that will actually equal or surpass dlp, but for right now, lcd displays needs all the help it can get.

Spec numbers are only a starting point in deciding on projectors. It is only through actual viewing that you can tell whether or not the the pj does what you want it to do.

you mean turn off the lamp? this is not valid.

I think all Phuton's saying is that commercial specs "cheat" a little.

yes they do, but not more than what we can do as well;

example;
the max ansi lumens spec on a comertiual unit is stated that way;

take 100 units, setup them as bright as posible all with new lamp. Then meassure all units brithness. take the brightest meassurement (1 unit) and that's the max lumens output for that model.

I found a real unit were the average brightness was 1700 lumens, then there was 1 at least with 2003 lumens. So they stated that model to have 2000 max ansi lumens. Now, it is posible to find a new projector (new lamp) with 1400 max lumens output (if average is 1700, and there was one with 2000, why shouldn´t be one with 1400?).

So your new projector (2000 max ansi lumens stated) could perfectly be 1400 max lumens. Conclusion; Yes, they cheat us.
