I recently purchased a home that had a home theater; I am currently updating the audio components and have been playing around with the projector, a Marquee 9500, with a Apple TV connected directly to the projector's HDMI card. I have been pretty happy with the video quality thus far, but I did notice that the light from the projector's bulbs/lenses reflect off of the screen and cause a colored glare. I've tried sitting in different parts of the room but the glare was still evident. It doesn't ruin the home theater experience, but it definitely is noticeable.
Are there any methods to reducing or removing the glare from the projector? I'm a CRT novice so any sort of help you can provide is more than appreciated; I've already tried to find some resources online, but only found solutions to reducing glare from windows and lighting.
I forgot to mention that the theater is in the basement and is not subjected to any natural light; when I have been connecting the Apple TV to the projector I have closed the doors and turned off the lights to make the room as dark as possible.
The glare is coming from the projector specifically; I can try to get a photo to you guys tonight, but it could also day a few days.
What your describing sounds like hot-spotting,and it's almost always attributed to the wrong screen material for a certain type of projector (different projection technology's require different screen material). I'm going to take a guess and say your screen material is either silver(ized) or some other pearlescent type high-gain (high reflectivity) material? These are typically 2.5 or higher gain and they're terrible with CRT with the exception of Draper High power fabric.
The most common choice for CRT is material in the 1.0 to 1.3 gain which is either flat white or satin-white in appearance.
I am confident in saying that it is a 100" screen (has Vidikron on the frame, but probably just branding) - what I can't tell you is what material the screen actually is. I suppose the screen is more of a "pearlescent" color than flat white.
One thing that I do know is that the gentleman I purchased the home from was very particular about the equipment he installed. Unfortunately, as the pictures will show beneath the screen does reflect light kind of well.
Defiantly a problem with that old crappy projector... mate just take it down and junk it.... actually i may want to use a few bits off it..... want to sell it to me for 50 bucks???
Shut up everyone
Nah as prev said i'm quite confident its the screen as well (which is a bit wierd being a vidikron and all)
Enjoy the CRT journey its a fun one....not everyone gets to startoff with a 9500!!!!!
Up the bid about 20X and you have a deal. I even have the box and crate the thing came on - I assume it was similar to the way they transported King Kong.
"Can you take pics of the lenses with out the PJ on, into the tubes with an LED flash light lighting up the tube face? Use no flash."
I can probably get that done tonight or the next day. The projector is on a Chief Lift so I can bring it down a little; I haven't used it yet but I assume it will just kick on a lower the projector for a closer look.
I do not know how much the projector has been serviced, but what are the chances that this is in fact an issue with the projector and/or its settings? Or is this a matter of updating the screen with a cloth more suitable for CRT projection?
I'm starting to think that replacing the screen is going to be the logical next step for this home theater. The actual material doesn't look to be too expensive in comparison to the rest of the components I am updating in the theater. I don't think there is anything wrong with the frame - so I should be able to just take the material/screen out and "simply" replace the fabric, right?
Since I already have a frame all I need to do is buy a roll of material/fabric, right? Or do you guys recommend just buying the whole shebang (frame, fabric, etc.)?
Update: I actually had selected the 16:9 100" screen in CeniWhite, but for some reason it defaulted to that other screen in grey; same with the URL you listed, Nashou66.
Look up Hurley Screen. Give them a call matt white material is nice but I think you can go up to about 1.3 gain . the guys there are very knowledgeable and if you tell them you have a frame and what kind they might be able to
find a perfect fit for you. They make screens for the movie theaters etc. I got my 13 foot wide screen for 300 bucks. Yours will be much less.

I looked on some sites and was able to find some rolls of the stuff - overall, most of the good stuff was going for about $65 to $80 for a roll of white, matted material. The higher end stuff was going for $150 to $300 for just the material.
I ended up buying the Elite screen with the frame for a few reasons:
1. Installation - I might have frame already for the material, but I have no idea what is behind that frame and how the material attaches to the frame. Buying everything together will most likely save me the hassle of needing to run to a store or trying to find "how-to" directions online.
2. Timing - My wife is going out of town this weekend, which gives me all the time I want to set up my home theater. Thanks to Amazon Prime Two-Day Shipping I just got my Sunday project.
3. Return Elite or Sell Current Screen - I'm happy to either return the Elite screen or sell the current screen after I take it down.
Update us man... hey another thing i thought, if direct sunlight has sat on the lenses it can cook the c element.... do the white paper thing to test man
Crazy - I thought I did send an update, but maybe it didn't go through.
Well, I installed the Elite 100" CineWhite last weekend and WHOA what a big difference right away. I do not have the best comparison photo to send at the moment, but here is one I took from Game 6 of the ALCS series. You can clearly see a significant different in the before and after:
