A couple pics. One is of my dad holding the frame we built yesterday. Another of BFG in 1080p. It's a dark scene with all 5 windows open in my room and the French doors to the sun room open. It actually looks much better in person my camera is dulling the image more. This is still impressive as this is with my px747 on standard mode nothing else adjusted.

The other two are from last night's celts game. In cinema mode on eco.
For some reason your pictures won’t show up when they are clicked on. Regardless I reached out to Stephen and he is going to let me return my setup and go with something else. After doing some measuring, even if I went down to a 110” screen, the solid surface would be tough to get into my basement. With that being said, I think I am going to go with a standard fixed frame from Stephen. Since I am getting a new screen I asked him about going with the Pulsar instead of the Abyss and he was nice enough to send me a sample. Once it comes in, I am going to hang it in the center of my Abyss screen and watch for a few days. After reading this thread, there doesn’t appear to be any negatives to going with the Pulsar over the Abyss but I will definitely post some pictures once I have the sample. I am pleased with the performance of the Abyss so if Pulsar is somehow an improvement on that, that would be great. Stay tuned.

Let's try again. I do notice some subtle hotspotting where the light hits the screen directly. With the abyss it wasn't noticeable. I am exactly 15ft away at 120". If I had more distance I'd probably go back another for or two but I'm maxed out

I think the Pulsar might be less forgiving about a less ideal throw-ratio compared to the Abyss. I don't remember your throw-distance, but if you're unable to get the projector at least 1.5X your screen-width back away from the screen (or farther, ideally), you might get some uniformity issues which are more visible/bothersome from the Pulsar with an overly close throw-ratio.
You're probably fine, but if your PJ is closer than 14ft-15ft you might want to consider either moving it back farther or switching to the Abyss material if you notice problems with the Pulsar.

EDIT: just saw the post above once the page reloaded after posting. I didn't mean to copy it, but it's nice to hear the same thing I suspected from somebody with hands-on experience using both materials.

The simple...and only correct answer...



The Pulsar works best at 1:8 Throw distance Ratio.

I would agree when I get rid of my 747 and get something to replace it I will be trying 110" at 15ft. Which is right in the 1.8 sweet spot. I'm thinking that will be key.

120" should be about 16ft away which puts me just shy of the sweet spot.

This is great news because my projector is just over 16’ from the lens to the screen. I am concerned about hot spotting which is why I think hanging the sample in the middle of my screen would make the most sense. I appreciate the input as it sounds like my setup is pretty ideal for the Pulsar. What would be even better is if Epson unveils the specs for their replacement to the 5040UB as I am hoping that is my next projector to replace my Epson 2150. Just want to make sure it would play nice with this screen but I assume it shouldn’t be a problem.

Hmm, I was considering these screens (110" Pulsar) for an untreated room, but at 110" I'd be sitting about 11ft from the image and with no room to move back. Sounds like I'd be having hotspotting issues here?

Go with the abyss then. That should work great

Would that be bright enough for daytime viewing? Planning on using a JVC 570 which isn't super bright and was thinking a higher gain screen would be better.

The Seating distance isn't the Factor...it's the Projector Throw distance that needs the 1:8 Ratio


A 96" wide screen would need to have the Projector at 14.5 '

The projector would pretty much be throwing from the seating distance (11’3”).

Well that does present an ungovernable issue for the Pulsar,and really...possibly if not probably for the Abyss as well. The Abyss needs a 1.5-1.6 ratio, and 11'-3" is on the bloody side of 12' (1.5 ratio). I'd have to say it would be problematical at best....with the only thing really offsetting potential issues at 11'-3" being the sub 1.0 gain of the Abyss. I strongly suggest you let Stephen weigh in on the matter.



No chance for a "Through the Wall" or "Partially Recessed" PJ installation?

BTW...the x570r can easily ace out a splendid image the Abyss at 11'-3"...which is the absolute closest the x570r can be and manage 110" diagonal. (...and at 0.7 gain it still gives you 32 fl !!!!! )

Thanks for the responses! I'll reach out to Stephen and get his take on it. Unfortunately I can't do a recessed install or a through the wall install :-/

I remember seeing the Abyss advertised as useable with ShortThrow projectors. I'm glad to see more accurate information getting around now.

Initially, the needed Throw was determined by the degree of light dispersion from the Projector. A "normal Short Throw" PJ's light cone widens very quickly, and if light uniformity is good, it could indeed be serviceable on a DES Abyss if placed correctly.
Also, it was never a case that a truly Short Throw PJ (110" diag @ 3'-4' or less) was alluded to being serviceable. By Short Throw, it was inferred that DLPs such as the BenQ w1080ST (120" diag @ 6'-6") or the Optoma GT-720 (120" diag @ 6'-1") could work with the Abyss 0.8



It quickly became apparent that the odds were stacked against that being the case the majority of the time, so it was decided to just retract that concept as being valid. Using PJs w/normal Throw range at the proper distance, light uniformity became almost a non-issue.


What you saw "advertised" had to be from just 1-2 posts almost 4 years ago, and since it hasn't been mentioned since, the "accurate" information has been around for a long, long time. Where have you been? Waiting toss in a hoary old, out of date Zinger?

Is there any way a particular placement using a significantly longer (albeit still shorter than recommended) throw-ratio could be correctly used In a way that's helpful for xblader with the 747 and Pulsar or megabadd and the Abyss?

Sadly these screens were being advertised in the DIYscreen section for over a year before that website was setup.
I think once Stephan himself began actively posting (both in the website and on forum after a hiatus) most of the sillier exaggerations started getting corrected. He's mentioned a lot of his own experience with his screen involved a slightly shorter than recommended throw-ratio, and although he didn't recommend it, he was personally happy with the setup. He might have some helpful tips from his hands-on experience for this exact situation.

Then again maybe you’re doing 16:9 and it just won’t fit like you said before.
If you could take a picture that would be great. I would like to stay with the 120” but am concerned I can make it past the landing of my basement stairs. I can send it through my window but the corner to corner dimensions are 53” and the vertical dimension of the screen is 59”. If I could go that route, that would be the easiest but we are talking 6” of flex here. Do you think thats possible? Picture of window is below. I am looking at a 16:9 screen as that is what I have from Stephen now.
Sorry this took so long. I’m with you I wouldn’t risk it through the window though. 6” of flex to 59” of height seems like pushing the limit. I’d say we flexed our screen 6-9” along the 120” length of the screen, no problem at all. I think the safer bet would be the stairs, unless your landing is a 180 degree turn. What’s your landing look like?

OR switch to 2.35:1 go CIH and slide that puppy right though the window! I’m at 120” x 51”, 131” diagonal, easy peasy, Lol!
You’d lose some height in 16:9, but more than make up for it in immersion with your movie’s. Depends on what your mission requirements are.

In my defense I did post these pics that day on my screen thread, just failed to put a link here.

The only "significantly longer" throw -ratio that would matter would be one that is within a foot of ideal for the Pulsar and 2 feet for the Abyss. Even then, one must take into consideration that the nature of the Screens themselves combined with the Projector's own performance tendencies is going to to vary to the point that no matter what else, Stephen is going to almost assuredly insist that the advised Throws be held to.



Certainly some who really want a DES screen, and who must fudge on the required Throws a bit might willfully accept a bit of gain loss at the edges of such tremendously dark screens...but that possibility must be both known and accepted going in. Stephen himself does a fine job of expressing both the advantages and limitations BEFORE anyone plunks down cash. I really do not think it's conducive to keeping people satisfied by suggesting that people spend to test the limits of acceptability any more than it would be for people to purchase a DES screen, set it up wrong, then expect to return it when it doesn't do what they were hoping it might.

Care to explain what you deem to be "sillier exaggerations" and where they hailed from? I hope you can, otherwise it's becoming very old how you seem to always make such off-the-cuff remarks.

Would it be okay to explain in PrivateMessage form?

Just to make sure I understand this correctly. If my screen width is 104" (120" Diagonal Screen), my ideal distance from screen should be around 15.5' away. 104" x 1.8 =187. 187/12 = 15.6. Is that correct? If so, I should be plenty good since I am 16' 1" lens to screen now.

Yes...and the Lens should be as close to the Top edge of the Screen as possible.

Is there a comparison between pulsar and abyss? understand the pulsar have better light rejection. apart from that how about color, black and PQ if 2 of them are identical or pulsar just superior in all expect?

Perhaps someone has had the Abyss 0.8 and then switched to the Pulsar 1.4 who can make their own objective comment. As far as I can relate, the Abyss 0.8 does produce the absolute deepest Black....and has extremely good "Ambient Light Resistance" due to it's depth of Ultra Dark Gray shading and Angular Reflective-ness.

The Pulsar 1.4 also produces almost Interstellar levels of Blacks, but because of it's higher gain it qualifies as being more inside the "Ambient Light Rejection" category...

Image quality (Black & Shadow detail -Colors -low incident of Artifacts) is equally good with both Screens.

Both screens have a low incident of Angular Reflection...but enough to warrant the PJ's lens being placed at the correct height.

But perhaps the biggest advantage the Pulsar 1.4 has over Abyss 0.8 is that it's gain allows for much improved viewing when 4K HDR content is being watched. (...as well as when the PJ itself has low lumen output...)

Stardust 2.0 is the latest iteration, focusing on delivering fully 2.0 gain while still maintaining a 50 degree Half Gain. Ideally suited for 3D enthusiasts, and those with 4K PJs whose HDR performance is very dim. It is not however as good at ALR performance as are the much darker Abyss 0.8 and Pulsar 1.4, and it requires a Throw Ratio of 2.0
