The only thing more annoying than someone putting 100 super bright LEDs in their backbox and causing the whole playfield to wash out with glare, is the glare from the DMD display itself.

I play completely in the dark, so glare bothers me more than a regular guy who's mom makes them leave some lights on because "playing in the dark is bad for your eyes".

My eyes are 75" off the ground, so I'm also at a worse angle for glare than the normal six foot tall guy.

Most things I buy are a disappointment or only work half-ass, so I'm pretty critical when I review something.

Continue please

At the pinball party last night, Mike and Lee both had glare guards on their games which made me look up some. Actually almost bought some today.

The DMD Glare Eliminator does not come with any instructions, so I'll give full install details near the end of the review.

WHAT DOES IT DO EXACTLY?

The DMDGE allows light to only travel in a single direction. It does not allow it to leave at an angle and reflect off the playfield.

DOES IT DIM THE DISPLAY?

As you can see in the picture, it dims the display very slightly. But if you did not know it was there, you would never notice.

A bonus is that it makes the display have more contrast. The background becomes darker, so the overall contrast increases.

HOW MUCH GLARE DOES IT ELIMINATE?

Literally 100%.

There is not even the slightest glare from the display on the playfield glass, no matter what angle you play at.

-
I mounted a camera with a wide aperture lens to a tripod at exactly my eye height and angle. This way I could make exact "before and after" pictures of what you would actually see playing the game.

Here in this picture I taped the DMDGE onto the front of a rather dark game The Shadow.

I only covered the right half of the display.

As you can see, there is no reflection on the glass at all !

On a game like The Shadow, this makes a big difference.

If Comet's is based on the 3m privacy film stuff....it works amazing.....I bought bigger sheets from 3m and cut them to fit ( before these were offered), but game changer for me ( however, I'm only 70" tall, so will have to get on a stool to verify @ your height).Good luck....mark

#5 5 years ago

Now something this cool can't be as easy as just taping it to the front of the game.

If you do that, you can see secondary reflections on the display itself (as you can see in the picture above).

So we have to open up the backbox and attach the DMDGE to the front of the DMD display itself.

-

Here I have installed it properly into another dark game, Attack From Mars:

Pretty amazing, yes?

And again, the camera was locked on a tripod in the exact same position for both photos.

"slight" darkening w the 3m stuff....but not noticeable at all.....nice that it comes pre cut ( and potentially less $...can't remember what I paid for the other sheet....something like $50, but made 3 sheets out of it)....Hooray Comet!!!

#8 5 years ago

Sold

Just ordered 6. What a great salesman vid is

INSTALLATION

==========================================

It is easier to take the whole speaker panel out, since it is probably filthy with 20 years of smoke and grime.

Disconnect either end of the ground wire, the power connector and the data connector.

There is also a speaker connector that did not make it into the picture, lol.

6.jpg
#10 5 years ago

Now the panel out, you can work comfortably while seated.

Remove the 4 (or 3 if you already did the Ground lug) #2 Philips screws.

7.jpg

#11 5 years ago

Now you can remove the insulator shield and the DMD itself.

8.jpg
#12 5 years ago

Polish out any scratches or haze with Novus #2 and a soft cloth.

Don't use paper towel, it will make more scratches.

If you've never cleaned the inside of the plastic protector window, it will likely be very dirty. You will be glad you took the whole panel out when you see the brown nicotine stains on the rag.

#13 5 years ago

The face of the DMD is actual glass.

Spray some Windex on a paper towel and carefully clean all the smoke, dust and finger prints off.

Don't spray Windex directly on the display.

The display is fragile and expensive.

#14 5 years ago

The adhesive is a little tricky to apply, but not difficult at all.

Remove the white paper protector, the adhesive stays behind.

Now press the adhesive onto the face of the display, rub with your fingernail and the adhesive will stick to the glass.

Obviously, don't put the adhesive blocking the dots themselves.

11.jpg
#15 5 years ago

Put the adhesive around the perimeter of the display

12.jpg

#16 5 years ago

Finally, place the DMDGE centered onto the display.

Start at one end and move across so you don't end up with an arch in the center.

The DMDGE has a protective film on both sides of it.

The shiny side of the film (marked peel #1), gets stuck to the adhesive.

The dull side faces the player (it is marked peel #2).

The DMDGE comes with a cleaning cloth you can use to press the film into the adhesive without scratching it.

Reverse the steps to put the panel back in.

Don't forget the grounding lug.

#17 5 years ago

Looks nice.

#18 5 years ago

One reason I never ordered these before is it always seemed to be fly by night people, or someone who didn't answer emails, or who was sick and you didn't know if they were still running the store etc. Comet is super reliable and trustworthy and on top of orders, so buy with confidence.

#19 5 years ago

Comet is great, slightly darker dmd but better contrast levels.
Art... please ship these to Canada.

#20 5 years ago

I thought Novus 2 had a bit of abrasive quality myself. I had always heard on plastics to only use Novus 1.

#21 5 years ago
Quoted from DugFreez:

Novus #2 will remove fine scratches from most plastics.

If you have no scratches on the display protector at all, then all you need is Novus #1 - but most these old games will have a ton of scratches.

#22 5 years ago

Vid,

Does it affect DMD visibility off to the sides? Can other people see my score as I play or do I just tell them how good I am?

#23 5 years ago
Quoted from MrArt2u:

Everyone to the sides has a perfect 180* view.

Anyone standing directly above you on a balcony, or an overhead camera would have a blacked out display.

#24 5 years ago

Have used several of these from other people previously. Awesome if you have a LED DMD (Xpin or stern) or just a plain ol' plasma.

#25 5 years ago

Thank you Vid, for this review....I appreciate you taking the time to share, and document better then we have had a chance to. I hope it is OK, to officially use your pics on the site?
(Ill have staff send you a couple more on me for this work....we simply run out of time)

The site is having issue with this product...Ill work on it today..
My headache is it requires separate shipping, it is so thick, it doesnt bend!
I hope to have this fixed later today...sorry about that.

Quoted from Razor:

Art... please ship these to Canada.

Ill check out the cost, and send you a PM....I felt it was costing too much to ship alone, but Ill check again.

This product was normally $30-$40 in the market...really a bit too much.
We are making only a few dollars, its not the money, I wanted this to be as low as possible since to me and others, its almost a "Must Have". We have negotiated a temporary exclusive, pending volume, so I hope to earn this exclusive, and grow this product in stature, and pricing.
Id Love to see New Sterns have this included in their games too!

Questions have been asked about Backbox...Unfortunately shipping from China here, unless by the pallet/Sea, and shipping out, along with DMD, would be too close to PDI/Invisiglass...
But I havent given up, and are working on possibly a solution.....

Thanks for the support guys!

Yes, of course you are welcome to use them.

Had I known they were going to be used in some official capacity, I would have done better on the installation pics (my good camera was locked on the tripod).

#27 5 years ago

That is one hell of a score on Shadow!

#28 5 years ago
Quoted from vid1900:

They are perfect and insanely appreciated...!!!!!

I believe they are OK on site...we had to add a small handling fee of $.50 each, because they ship separate
So $3.00 to ship 6 pieces......

#29 5 years ago

Now that we have addressed the DMD glare issue; what's the solution for the backbox glare?
Vid? Art? A larger sheet for the translight glass possibly?

#30 5 years ago

Thanks for the write up Vid , it answered a lot of questions I had about this product..

#31 5 years ago

Currently, because of the thickness, a Large sheet after import costs and shipping costs, would make
it as costly as PDI/Invisiglass. (My cost, plus import, plus shipping out, no profit is around $240-$250)

However, They are testing, if they can possibly make it thinner, to roll up...Then it would work.
No answers yet...50/50....It needs to be below $100 and hopefully by a lot, I think to be at the right price..
The counterfeit ones I tested, were rollable, and inexpensive...but failed...

So, still working on it.....

#32 5 years ago
Quoted from Razor:

Art... please ship these to Canada.

If you make shipping available to Canada, I will take several as well! Maybe some more leds as well. Keep us updated please.

A larger sheet would be great!

But for the time being solution, remember to use single LED bulbs, and don't fill every lamp socket.

Everyone thinks they need super bright LEDs for the backbox, and they don't.

Everyone thinks they have to fill every socket with a bulb, and they don't.

I've been using frosted, single LED bulbs and they work pretty good (but a full sheet of Glare Eliminator would be better, lol).

Thanks.

I need to keep my batteries fresh, because I might not get a score that high again, lol.

Shadow is a hard game

There is no problem to ship to Canada, on Monday, Ill get the adjusted shipping....

#36 5 years ago

From the pics, these look like good glare filters. I had a friend that bought some cut rate glare filters that were way to thin and flimsy. After being installed they would have waves in them and continue to curl even worse. He finally pulled them all and trashed them. It was a case where he would have been better off in the long run spending more money and getting a higher quality film.

Thanks for the overview and review vid1900.

#37 5 years ago

Gotta try this, thanks for the heads up. Would love to toss the plastic spoiler style glare guard.

#38 5 years ago

Congrats to Art and vid on this.
Might do this later on my STLE and STNG. Just not in a super hurry as I have those plastic angle pieces.

It's all Art.

The only thing I did was install one

You get credit for documenting the install.

#41 5 years ago

Thanks Art.

#42 5 years ago

Anyone use one of these with a ColorDMD? I've always used the bent plastic type, but having something hidden would be nice.

#43 5 years ago

I would imagine they would be fine since 3M designed this for Laptops, Tablets, and phones....all color screens, with
less brightness....

#44 5 years ago

I have one of the 3M screens on one of my computer monitors here at work. It is for privacy since I am in health insurance, and lets me surf Pinside while still looking professional. (Of course I only look during down times and already do the jobs of 4 people at this point due to "restructuring.") My former boss called it my "porn screen." Just this one was at least $240 through Staples with our corporate discount for a 22" widescreen. It is crazy expensive, but works nicely. I'll have to get a few on my next bulb order to try them out.

#45 5 years ago

A small bump, as we are almost sold out of these....Every game that has a DMD should have this!

#46 5 years ago

Thanks Vid!

May be you could talk to Stern and others to incorporate them into the LE package.

I'm out.

#49 5 years ago

I'm sure if they did it would be the cheap, cut rate version of these. Plus....doesn't the new speaker panel design angle upwards to make the DMD glare a non-issue?

Quoted from DugFreez:

It cut's it down some but it's still there.
