With the new FP coming out soon I thought a thread about what is the most important PQ issue for you.I know Black level and contrast get alot of headlines.Color is important along with sharpness resolution.But for me if the Pic is dim then everything else does not matter.I like a pic with some pop.I have seen many expensive FP that some say are great but they have a dim pic.I have to have brightness first then color then blacks then sharpness.Feel free to disagree.Just want some opions.THANKS BOB:D

Brightness is going to depend on screen type, screen size, throw distance, and ambient light control. No PJ will look good if you don't have these issues under control.

"with the new fp coming out"


uhhhhh which one? theres probably more then one coming out..........:)

Brightness is an interesting PQ attribute for discussion. Most other PQ attributes you can define what is desired.

black level - The 'blacker' the better
color - The more accurate the better
contrasts - yada, yada ...
resolution - Well I'm not going to say the mo's always the better. Anyway more resolution can't be worse than less.
brightness? - As reconlabtech pointed out is very dependent on your HT setup. IMO as long as you can keep other attributes optimal get whatever brightness you want. If color becomes funky and black appears too grey what's the point?

It sounds like you would like a PJ that can overcome the weakness of not performing well with appreciable ambient light in the room. Is that correct? I agree that a PJ that could deal with ambient light as well as a plasma or LCD would be nice but the ambient light issue is one I am willing to overlook in order to get a huge display at a fraction of the cost of LCD or plasma.

Well said.

You can say that about Black levels also.Depends on Screen type' room color' ambient light ect.My question was what's most important when buying a new fp.First thing I look at is how much light can it produce.If it is a dim machine.Then I scatch it off my list right then.

So what's your lumens cutoff?

If you are beaming 2000 lumens then all you have is a perceived black level and not a true level at all. The higher brightness and whites make you think the black level is deeper but it is actually less.

Once calibrated, nearly all the ht pjs are about 350 to 600 lumens.

Well, don't forget motion, scaling and interlacing while you are at it. All of course are important, but these draw attention to themselves.

You are eliminating a lot of good projectors that way. A front projection system is just that a system, not just a projector. You have to look at both the screen and the projector and match them together. A high lumen projector using a 1.0 gain screen can and often does put out fewer foot lamberts than a "dim" projector using a higher gain screen. Also as Reconlabtech said once calibrated there is not near as much difference between the "dim" projectors and the "bright" projectors.

High gain screen's suck.I would never own one.Most who post on here want a FP that they can use for Sports Movies Games ect.I have seen calibrated fp that with some light on in the room and trying to watch the super bowl'the pic sucks.Most do not sit in a bat cave by their selves in the dark.So a fp that has the Gas to light up a screen with ambient light is highly sought.But I know some need a high gain screem because they bought a dim fp'like most sony fp's.HG screen's only do one thing right and do alot wrong.Just some of my observations.Also look at all the post that members have posted about noy buying a 1080p intill they have more lumen's.:)

Not posted here yet but is also a deal breaker for me, a FP that performs well but has a roaring fan that spoils the experience.

I have a Dalite Wide Power screen and it performs excellently. The gain is 2.8, it has a 45 degree viewing cone, and it does not use glass beads. However, I discovered that any direct light on a screen will negate most of the benefits of any PJ, even the high lumens models. Rather than go the increased fL route, I painted a gray screen and provided better controls on any direct light hitting the screen and got results I like better than just pumping up the overall brightness. We watched many USC, Navy, and Cowboys games last year and did not have to sit in a closed, dark room to do it. The proper window shades during the day met most of the light control I needed and the gray screen helped add contrast back to the picture while battling ambient lighting.

Loud fans also are a deal breaker for me to.Thanks for your insight recon'Those HP screens have to have the fp pretty much mounted right in the middel to get the benefit I see.Allmost NFL time again.YEHA

So you are saying that screen foot lambert achieved by higher lumens gives a better image than the same screen foot lambert achieved by a lower lumen projector and a screen with gain? That would make for an interesting blind test. Everybody does not have a room that is conducive for a HP set up. In my case the HP works while ceiling mount (17' ceiling) is not practical. Also my image looks pretty good with some lights on (enough to read by) in the room.
