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

Thank you for the explaination, MississippiMan.
Any guideline, how many lumen shoud consider what gain of screen? 1500, 2000 or 3000 lumen like optoma UHZ65?

MississippiMan · 06-06-2018, 11:38 AM

Well....the size screen has much to do with any such recommendation. But using the UHZ65 & 120" diagonal as a guide post........:

120" diag. Abyss 0.8 w/188" Throw = 24 fl

120" diag. Pulsar 1.4 w/188" Throw = 42 fl

Both have enough for good to fantastic HDR

If you went with the Abyss I would NOT suggest any lower Lumen output than 2000, unless it was a JVC DLA-x590r ^/up

Does Dark Energy offer any screen samples? I looked but couldn't find any on the website.

I was told no.

I have had both the abyss and now the pulsar. I will admit it would be impossible for me to compare the 2 seeing as I changed out projectors at the same time. I will state a couple things. I ran about 13ft with the abyss which seemed perfect at 120" I have 15ft now with the Pulsar and wish I had a little more throw. You do get some slight hotspotting just in the upper center directly where the projector light hits.

The blacks are darker on the Pulsar but, that is due to the better projector. I would agree with mississipi I believe the Pulsar will give you similar blacks to the Abyss maybe just a hair less deep/dark. However, with that said the extra brightness is unreal! It feels night and day different to me. If I really needed to combat ambient light and had the throw distance then the Pulsar would be my go to. If I had better light control I would probably lean towards the Abyss.

Again take this info with a grain of salt seeing as I made multiple changes simultaneously to my setup.

riddle · 06-07-2018, 05:29 AM

Looks thats this DEA Pulsar 1.4 is good choice at all...

But i am not sure if this will works in my setup and i have so many question... and more will come later :-)

-will this works at Epson 9300W/5040UBe with 19,68ft distance from the screen? I am kittke worryed by thats hotspotting.
-And how is going thats waves at white/bright scene? If i will take just DIY screen material?

How large is the intended screen?

The throw distance you listed could service a Screen up to 10' wide. (120"x 50" 130" [email protected] 2.35:1)

It is a safe distance, and unless your watching 3D or HDR content, you can run the 5040ub in Economy Mode for all othrer applications

Hi, my max size of screen is 120" 16:9, thats is size what i use right now.

And yes some times i am watching 3D but most time i am using it for HDR content.

This is one slight road block of mine. It's not the end of the world for me to move the PJ shelf back another foot or two, but currently with a 120" wide screen, the PJ is the min. distance of 15ft from the top of the screen. Thanks for pointing out you get a little hot-spotting. I guess I could toss one up and see for myself. One of the few joys of a drop-ceiling I guess.....easy cable and PJ shelf management...

I recieved the sample on Saturday and was watching some content on it as much as I can over the weekend. I hung it from the top and middle of my screen to compare it directly to the Abyss. I was concerned blacks wouldn’t look as good either as I know my projector isn’t very good in that department (Epson 2150 just over 16’ away). I would say there is essentially no difference in black performance. If anything the blacks might look better because the colors and whites are brighter. I am going to try and take some better pictures with the DSLR but see the one attached from my iPhone.

how about 92" diag. Abyss 0.9 with Sony VW385ES but only lumen output 1500?

Where the heck has @LumensLover been? He was posting 50 screen shots per day for a month. Has he moved on to a new and better screen and projector again?

Bud, I was thinking the same thing the other day then saw this. Don’t know what happened...

PhilipLG · 09-14-2018, 01:59 PM

Hi Lumenslover, I read your review and the thread and really appreciate your inputs. I currently have a 82" Stewart Firehawk G2 screen with an Epson 5040. (The old Firehawk G2 has a 1.3 gain). I want to upgrade to the DE Abyss .9 or the Pulsar 1.4 but I am not quite sure which screen would be better for my setup.

I calculated that if you are using the Sony HW45ES to project onto your 110" screen, you should be getting approximately 25FL brightness.

My Epson 5040 projector is mounted 16.5ft from the screen, so I calculated I would get approximately 85FL brightness onto my 82" screen. Does this mean it would be better for me to take the DE Abyss .9? I am just a bit worried that it would not look as bright as my current old Firehawk G2 with the 1.3x gain, or what do you think? Is it fair to compare a Firehawk 1.3x gain to a DE Abyss .9 gain, or is it two completely different things?

How would the DES Pulsar match with the Optoma UHZ65?

Set up properly, it would be spectacular. OLED-like imagery....no foolin' !

Having said that....the one thing that could be a bit of a spoiler is the UHZ65's high Lumen output combined with a very low Brightness Uniformity (56%), unless you can do the opposite of what is usually the norm and set the PJ back at least 2/3rds of it's maximum Telephoto range for a given screen size. This is somewhat of an advantage with a Pulsar anyway, and of course you would be able to use the Cinema or Reference settings at one of the several lower Lamp outputs offered.

The lack of BluRay 3D support and no Lens Memory put's it as being low Man on the PJ Totem Pole for me personally, but for someone who wants to see 4K Movies and TV (...and still see deep Blacks w/detail) in a room where ambient light is just plain unavoidable, the combo of PJ / Screen as listed will certainly be more than impressive.

Sam Ash · 10-18-2018, 08:13 AM

Reading through this post has been fun and informative.

LumensLover, loads of respect for you sir and thank you for your immense efforts and down-to-earth approach. Technical insights aside, you're probably the only person that has experienced nearly every ALR solution out there and that in my books translates to passion.

I love the concept of ALR screens. However, I am very sensitive and particular to image fidelity. The last time I saw an SI BD 1.4 in action, I noticed two things:-

1. The image was slightly soft even when the projector was focused correctly - this did not look entirely wrong but as I mentioned I'm really particular about an image. Maybe a slight sharpening overdose would have helped to fix the problem.

2. The image had a very fine texture to it - almost like the surface of the screen was made with crushed glass powder.

3. Subtle gradations are not as smooth - this could have been content related.

I do realise the fact that SI and other ALR screen makers keep improving the quality, have the first 2 issues been resolved or improved drastically ?

The DES Pulsar 1.4 and Abyss 0.8 seem to be nice products.

Have you had the privilege to see this combination in action ?

Sam Ash · 10-18-2018, 09:29 AM

LumensLover, is there anyway I can contact you? - Would like your assistance please.

If you don't mind me calling you or emailing you, then kindly share your contact details via a private message.

That combo? No. I have seen it with 4K Sony and JVC projectors however. I can't really elaborate enough....and to even do so would be an exercise in excessive and profuse exclamatory discourse about the overwhelming image quality in both Darkness and Ambient light.

As for the UHZ65's performance, I stand by my ad hoc evaluation. I do not / cannot trust in the use of any PJ with under 60% Light uniformity on a 1.0 gain surface, let alone a higher Gain one.

It may well be not the issue I perceive it to be...but I'll not go so far as to suggest it on such a "maybe".

A little over a year since the last reply on this thread. Any more disciples of DES? I'm about to get an Epson 5050ub and the ALR of these screens seems really interesting.

Anyone not happy with theirs?

I'm using it with my 5040 and still love it. Make sure you give it atleast 15ft though. The gain of the screen can produce Hotspotting if you are any closer

I'm quite happy w mine. follow the throw ratios accordingly and you'll be a happy camper.

Thanks! I have a range of 15-24ft that I can put the projector. The best placement as far as being out of the way would be approximately 20 feet. Is that in the sweet spot for a 110-120" on DES or is it getting a little far?

I'm not totally familiar with throw ratios. It looks like the ratios for the two screens mostly talked about in this thread are:

Abyss Throw Ratio: 1.6+
Pulsar Throw Ratio: 1.8+

I used a throw calculator for the 5050ub at 120 inches diagonal to get some numbers here. Image 1 is for the Abyss and image 2 is for the Pulsar.

According to these calculations, the projector could be placed anywhere from 11'9" to 24'9" in its Zoom Range of 1.35 to 2.84. Is the Throw Ratio the same thing as the Zoom Range? Do I just use this calculator and set the zoom range to 1.6 for the Abyss and 1.8 for the Pulsar and it'll show me the minimal and optimal distance to screen?

Should I got Pular or Abyss?

Yea 20 ft for the pulsar at 120" is great. I'm terms of which you should get if fully dependent on you and your situstion. Reach out to DES on Facebook. He's an incredibly helpful guy and can help you determine which may be the best for your application. I went from the anyss to pulsar because my light control is poor in my living room and I love/wanted the extra brightness and punch from the extra gain

FamMann81 · 12-02-2019, 09:12 AM

I’m right at 15 ft. with my Sony 665ES and still loving it. It’s been awhile since I checked in, but still don’t have anything but praise for my Pulsar.

Here’s my most recent pic from thurs night football on Nov 21.
