Anyone? There are 800x600 150 lumen models out now:

LG HS102 160 lumens, 2000:1 MSRP $600 Unfortunately only available in Korea right now.

Samsung P400 150 lumens, 1000:1 MSRP $600

http://www.samsung.com/us/consumer/detail/detail.do?group=computersperipherals&type=dataprojector&subtype=ultraportableprojector&model_cd=SPP400BX/EN

Presumably these use the same dlp chip and PhlatLight LEDS so how is the LG getting a 2000:1 contrast?

I'm thinking of maybe trying one of these out in the next couple months. If anyone has first-hand experience please share! :)

I'll get one for sure once they hit the $150-200 mark.

Thanks for posting the info.

I have a 1-2 year old model, Mits PK-20. It's rated at like 20-30 lumens but doesn't seem that dim. I use it for travel/vacation HT and it's pretty great, frankly. It's not like my 1500 lumen 720p DLP. In mixed lighting rooms (like when I'm teaching and people take notes) I use around a 42-50" image to improve brightness - so obviously it's only for smaller groups, and then for movies, with the windows blocked, I stretch it out to 60-70" (smaller in widescreen, of course) and it's terrific.

I know you guys are thinking about designated HT applications, especially those of you who go through lamps quickly. I think we're still a couple years out on that, but it's a fun toy and great secondary PJ. It's quiet, relatively cool (ought to be without any brightness) and turns off and on a lot quicker than a traditional unit. 'The fundamentals of the' tech are strong, will be interesting.

I'm very surprised how bright '20 lumens' appears. My HT projector seems 4-5x brighter, not 15x, so the 150 lumen models are a little interesting.

I paid $500 with a battery pack around 1 year back. The battery doubles the size/weight, but is great here in India with power outages.

You make a good point about low lumen output being brighter than you'd think. Microvision has a scanning laser projector coming out around April 09 rated between 10-20 lumens but you'd never know from this video:

I'm looking forward to a bulb-free future. :)

Update: The Microvision laser projector should be available in June 09.

I guess I need to stop skimming thread titles. I was like "WTF? Who owns an LCD projector? Probably half the people in this forum!"

Whoever took my helmet please give it back - my bus is about to leave.:D

Does anybody know if the Samsung P400 can accept HDTV signals? 480p through the D-Sub (15-pin) port? Will a D-Sub to component breakout cable work? I can't find anything on the internet.

Can anybody help? I spent one hour on the phone with samsung, an absloute waste of time. I would ask for support for "projectors" and end up in the "printer department".

I guess the best thing to do is to buy it, try it, take it back.

Looks like it is a native 800x600 image and the only higher resolution input is the d-sub port. It will accept 720p and 1080i signals through the d-sub input and rescale that to 800x450.

I was hesitant to answer because I have a different 800x600 LED PJ, but mine (Mits PK20) does take HD signals over VGA cable, and Component-VGA works fine. I set my XBOX to 720p when we're on vacation. 1080i also worked similarly.

Hopefully this model is the same - I agree completely with reconlabtech's answer, I'm just not 100% certain.

Well I broke down and bought one, I will keep you guys posted and I will take some good screen shots.

I guess we now know where ex BB.com employees found jobs.

Its here. I'm very impressed with the unit. Its mucher brighter than I expected. No Go on component video, going to try a transcoder. Will post pics later.

Yeah Lumen ratings can be surprising. I think mine's rated at 25 lumens or something (my HT projector is 1500 lumens) and - while not super bright, it is quite usable in reasonable lighting situations. I've read the explanation about the way the human eye perceives light and you have to like double before you see an appreciable difference or something like that. Bottom line, while these aren't recommended at all as primary HT PJs, they're quite fun and useful :)

Just to clarify, this is the Samsung P400? I hope you don't mind I've got a few questions for you:

What is the widest image you can project before the lens won't focus anymore?

What size image are you projecting and how close to the screen do you have to be before you see pixel structure (screendoor)?

If you are sensitive to them, have you seen any rainbows?

Have you owned any other dlp projectors and if so how would you rate the ansi contrast of this unit?

Thanks! Phlatlight LEDs are new to projectors so if you can answer any of these questions that would be fantastic.:)

Samsung P400 user opinion

"Personal Experience
I have owned many portable projectors before like the Viewsonic pj551... My first look at the projector when I unpacked it today was the external power supply for the unit. Bulky and big was not what anyone would be expecting. Only good news on the external ps is the rating 14vDC at 4amps which should make some people in the R.V. or mobile market happy that it could run of the automotive battery.

OK- On with the good's... Picture is cleaner than my Viewsonic pj551 and is on par with my more expensive Sanyo PLV-Z5. Contrast and color accuracy blew me away. The DLP chipset with the LED package coming from Phatlight & T.I simply rocks. I would rate the contrast around even with 5,000:1 when comparing it to my 10,000:1 Sanyo not the 1,500 rated. Also lumen output of the samsung sp-p400b only rated at 150 but puts out near identical levels of light with my viewsonic and sanyo's when configured for movie watching. I know this projector wasn't designed for the movie people but does have enough light output to shine on my 100" screen with no visible issues. The speakers work very well and will work any small - medium conference room.

Summery of my rant...
-Color accuracy is amazing for the price of the pj
-Headphone jack is a big plus
-Sliding lens cover instead of one that pops off
-Brightness is good for lit rooms up to 60" range
-Black's are almost at black as pj's costing Thousands more.
-Front / Ceiling / Rear / and Rear ceiling support
Can't wait for next years model and one for the Home Theater.

Problems
Only things wishing for more...

-No s-video or HDMI input
-No Zoom for the lens
-No supplied VGA breakout cable for component input
-Only 800x600 720p would be nice or 1080p option
-Only one pivot foot up and down not side balance
-Buttons on pj are VERY sensitive and take a wile to get used to so the remote is a must for the first experience."

Wow! It's in the same league as a Z5? Phatlight is a major break through, because while I like my PK20, it's not in that cosmo in terms of performance. Thanks for posting your thoughts.

Man, if only this projector was 720p. I'd be all over it. I don't need much lumens. Just the equivalent of 500 or so will do in Cinema mode.

The above review was not the poster's but rather someone's from projector central. Hopefully we will hear back from johnzo1995 soon...I'm also hoping we get a 720p or 1080p LED from CES in two weeks. :)

I'll get one for sure once they hit the $150-200 mark.

I completely agree... Definitely cool though!

To: Sisyphus

Just to clarify, this is the Samsung P400? I hope you don't mind I've got a few questions for you: Yes P400

What is the widest image you can project before the lens won't focus anymore? About 144"

What size image are you projecting and how close to the screen do you have to be before you see pixel structure (screendoor)? 100" (16:9), 7 feet

If you are sensitive to them, have you seen any rainbows? No

Have you owned any other dlp projectors and if so how would you rate the ansi contrast of this unit? This is my first DLP, Im a LCD guy

Thanks! Phlatlight LEDs are new to projectors so if you can answer any of these questions that would be fantastic, I love this projector

Here are my pro and cons for the p400:

Pros:
1. LED (How Obvious) I use it everynight, fall asleep with it running and don't even have to hold my breath about the lamp
2. Good brightness: during the day with 50-60" (4:3) no problem, nightime with good light control 120-144" (4:3) or about 100" (16:9)
3. Excellent color, good contrast
4. Screendoor is not that bad

Cons:
1. No Component Video
2. No Zoom Lens
3. Remote kind of sucks

Overall I think this projector is great, despite the 800*600 rez, the picture is very pleasing. I really really wished there was component input on this model so we at least can get 480p to the projector, however 480i from the directv box looks good.

I have some pics coming soon, took some last night, but I need to adjust the camera shutter to make it look like what it see.

Next model: (What I would hope for)
1. 1280*720 or 1366*768 LCD or DLP
2. Component, HDMI, S-video, Screen trigger, serial port
3. Zoom Lens
4. Better Remote

Thank you for answering my questions! :) It really sounds quite nice. I think next year we will see at the very least 4 more brands of LED projectors on the market. Looking forward to your screenshots!

here is one shot, the screen is about 10% brighter than it really is. FYI this is shot on a brown wall. I will try and get better shots tonight.

Wow! That is good brightness! If they can manage to cool the LEDs and make the blue last longer, with a 720p under 1k, that would be a great bargain.

projectorcentral lists the P400 as being able to accomodate (720p, 1080i) hd signals, so if you use a vga-component dongle you should see a dramatic improvement in picture quality. One this unit comes out in XGA (or better, probably by this year) I'm on board.

I swear I'm leaning toward buying this projector. I found it on amazon and it has 3 customer reviews and one from this month. Like some other have said it they just come out with an 720 or 768 I am definitely hooked you can't beat 20,000 to 30,000 hours with a stick.

Absolutely, they release this sucker in 720p, it's mine! And my guess is that they purposefully released them in 800x600 so that it doesn't destroy the bulb 720p market. Can you imagine if these were available in 720p for $500-600?

Any rainbow effect with LED DLP?

My guess is no, but I don't fully understand the tech.

Chances are, probably slim to none. If there is, it will be so instantaneous that it won't be very perceptible.

Heh. I found the answer just after I posted the question, so I erased it. But yeah, Samsung apparently claims LED DLP is not susceptible to the rainbow effect since there is no colour wheel.

Never needing to replace the bulb I would think people would just as easily spend up to $1k for one and just leave it running nonstop for years, I know I would :cool:

*edit* found a recent review from PcMag for the Samsung p400 (http://www.pcmag.com/article2/0,2817,2337305,00.asp)

Video quality when playing a DVD was disappointing. The projector lost much of the detail in dark areas, and the rainbow effect was even more prominent than with computer images—to the point of being seriously annoying for those who can see it. This is not a projector I'd want at home for watching movies, although I'd certainly consider it for projecting video games at large size.

:(

Rainbows, really? WTF! :mad:

Grain of salt I suppose. I did find a video review of it which shows it running a desktop, but still no video playback to give a better idea of capabilities.

I don't see rainbows, but I believe that review that says it has rainbow issues is just totally wrong and trying to sound knowledgeable about a problem with old, non-LED DLPs.

I think the tech is something like 3DLP - no possibilities of rainbows. I've read this on AVS a couple times. I never see 'em, so I can't say with total certainty - but one of the strengths of LED DLPs is the tech has totally overcome RBE (there's no color wheel!).

Rainbows are caused by the gap between colors in the timing and speed of the wheel. LEDs can do that too. If there's a lag in switching from LED to LED, Rainbows can be perceptible.

exactly, its not the bulb that causes rainbows its the color wheel. I cant find the specs on the color wheel speed which leads me to assume it might even be 1x speed since its not geared towards video playback.

*edit* ignore me I just did a search on phatlight and it looks like it doesnt use a colorwheel from this picture...

It doesn't matter if it doesn't use a color wheel. Single chip DLP relies on color cycling to produce a full color image. Regardless of the technology (color wheel, laser, LED) slower color cycling is more likely to produce rainbows.

Right what I was trying to say (and in fact said) was that there's no color wheel and they've overcome RBE with this new tech. Here's some evidence (although it pertains to RP TVs):

http://www.gizmocafe.com/tv-video/samsung-led-dlp.aspx

Like I said before - one of the big selling points for LED Projectors (aside from bulb life and portability/battery options) was the elimination of RBE.

Until I read that someone trusted (ie. an AVS user) experiences RBE with an LED DLP PJ, I'll continue to believe the issue has been resolved.

Here is one shot during overcast day. I have a component toVGA scaler coming to try on it.

Projector Central is wrong about the HDTV signals. 1. I tryed 720p component through VGA port, projector responed "Mode Not Supported"
2. Look through P400 owners manual under supported modes, HDTV signals are not listed.

Well that stinks- you'd think a projector made nowadays would at least support hd. Of course, if thats the case and you did play a hd signal regardless, resulting in a squished displayed image, this projector would be a great candidate for an anamorphic setup

lol good stuff

The projector handles 16:9 perfectly. I have a DirecTV HD reciever putting out 16:9 over composite (sretched the long way) then the projector squishes it down to 16:9 and the aspect ratio of the picture is correct.

Those claims belong back children stories crate.

I used to have one of those Samsung LED DLP rear-projection TV's (hlt5087s) and the rainbows were as visible as ever.

Light passes thru a spinning color wheel to produce different colors in a goold old DLP system. In a LED DLP, you have 3 led light sources red, green and blue which flash in succession. Same end result.

Here is another picture with the projector running off a Tekkeon MP3300 battery.

good info johnzo,

Right now thats 115" (16:9) more if the projector was set to (4:3).

Just to let you guys know, we are running the projector 14+ hours a day =).

I'm looking at my 360 box and in disbelief that the projector is that small.

From http://www.avsforum.com/avs-vb/showthread.php?t=1071205

HS102 also has internal decoder and able to play mpeg1/2/4/divx from usb flashcard.

Being an owner of Dell M109 you can put your opinion and pics in this thread:
Calling you out...who owns a LED projector? (http://www.avsforum.com/avs-vb/showthread.php?t=1072954)

Well I will have to bower a camera for the pictures my cellphone camera is high resolution but has a very tiny tiny lens.

I run it at about ~100" on my wall. It is mounted on one wall throwing to the opposite wall in an average sized rectangular bedroom. Screen door effect is minimal and half the throw distance away from the screen I can't notice the pixels/screen door at all.

It is not a very bright projector and at 100 inches I completely blackout my room to get the best viewing possible. Cannot use it with this size screen with very much ambient light at all. Turning on my room lights almost completely washes the image off my wall. I would like to purchase a screen but do not have the budget for one. I have an old da-lite screen but unfortunately its too small for the new throw ;) I am only guessing that with a high gain screen you could use it much easier with ambient light. Cloudy day with light entering the room but not reflecting too much off the wall I can watch movies easily.

As for color reproduction:

I find this projector has a lot of green/blue which you really have tone down. With some fiddling it looks quite nice, to me anyway.

As for picture quality:

DVDrips with Xvid really are not that nice looking. Playing 720p rips is where it is at. It does a decent job at displaying them. Not as good as my tiny pixel pitch LCD monitor but good none the less. I mean you can't expect perfectly crisp HD definition at 800x600 but definitely better the dvd quality.

Noise:

The Dell M109S is one noisy little unit. You can see a little 40mm fan in there just going nuts :D It can get pretty hot also. The fan seems to have very little if no speed variation.

Inputs:

The Composite input does not have any ?feedback? to the output device as far as I can tell. I cannot get it to output off my vista computer. I have not tried XP but I will. Conclusion for now is that you have to force output to it. The VGA seems to work fine.

Problems:

For me this projector has a huge flaw. It will not focus uniformly at all. I am trying to get dell to send me a new unit. They have failed twice to send it out. 10+ hours on the phone so far. As far as Dell has told me so far that is unit is definitely defective. I suspect something is just out of alignment. I will report back again when I do finally receive a new unit.

Can never seem to keep the unit even uniformly out of focus :p Seems to change on heatup/cooldown or maybe my cat is just moving it around by playing with the cables. It is just sitting on the mount with its own weight at the moment. I will strap it down later.

One other annoyance is it seems to have problems scaling some resolutions and can attempt switching a few times before it finally settles.

Features:

No remote is a real pain if your going to be mounting it somewhere. There is no wake-up/standby mode as far as I can tell. It turns itself off but will not power back on by itself.

Conclusion:

A bit noisy, need a dark area for large throw/screen, no remote, no standard mounting holes but for $500 (CAD) shipped I can't really complain as long as the new unit comes in with 0 focus issues.

I would recommend this more if someone was mobile. I love to have this thing with me on long trips as I can put a screen basically anywhere with a small car inverter!

Quality wise the only thing that worries me is the proprietary break-out cable/connector. It is definently not as durable as just the regular output jacks but I am sure this plays into the units very small form factor and weight.

Thanks for info. Change Dell to LG ;)

I just got my dalite 110" high power, lovin it. Will post pics later.

I have a real crazy idea, someone should take the 61" samsung LED rear projection engine out and make a projector out of it. My P400 has the Phatlight P121 chip set (4:3) the samsung tv has the Phatlight P120 (16:9) chip set. All you would have to do is change the projection lens. You can get a nice lens from a broken projector on ebay. And rig up some type of enclosure, bam $1300 led 1080p projector :eek:

dalite high power is the best way to go, especially with a low lumen projector like this. Its too bad there aren't more affordable high gain screens other than dalite but perhaps as more of these LEDs come to market that may change.

Where'd you get and how much for 110"?

I think it would be a better idea to buy the whole TV. The tv comes with all the input boards to drive the DMD engine. If you bought the engine from the parts website - I don't think it comes with all of the PCB boards to run the TV.

We should start a new thread on this, set up a paypal donation thing, and get someone to do it.

If and when 1080p LED projector come out and they are going to be $3000, this would be a $1300 DIY solution.

I love this idea. It's been in my head for a few months now.

Help me out on some issues/questions, please. Are these statements correct?

1. From what I can tell you wouldn't even have to buy the 67 inch Samsung, the 61 incher would do the job. Same internals.
2. The 1080p DLP chip in the Sammy is wobulated.
3. Light output is going to be low, so a high gain screen and a dark room are mandatory to get, say a 100 inch diagonal image.
4. The current generation of Sammys can correctly display a 24p image. If I understand correctly, they operate on at 120hz. All frames in 60fps signals are doubled and all frames in a 24fps signal are displayed 5 times.
5. New lens needed to handle different throw distance and focus.

I love this idea. It's been in my head for a few months now.

Help me out on some issues/questions, please. Are these statements correct?

1. From what I can tell you wouldn't even have to buy the 67 inch Samsung, the 61 incher would do the job. Same internals.
2. The 1080p DLP chip in the Sammy is wobulated.
3. Light output is going to be low, so a high gain screen and a dark room are mandatory to get, say a 100 inch diagonal image.
4. The current generation of Sammys can correctly display a 24p image. If I understand correctly, they operate on at 120hz. All frames in 60fps signals are doubled and all frames in a 24fps signal are displayed 5 times.
5. New lens needed to handle different throw distance and focus.
6. And most importantly, a direct front projection of the image straight out of the lens would result in a backwards image (left/right flopped).

Happy people from US and Canada, at ~$1500 you can buy LED DLP 3D :)

You can get a 2500 lumen LED array for under $200 USD shipped from luminus's phlatlight distributor. I might attempt to put this white high power LED in a DLP projector.

Sweet. If you decide to do that you will need to disable your projectors bulb detection and startup so it runs without a bulb. May not be exactly the same process for your projector but this should help:

Obviously projector should be unplugged and given plenty of time to discharge before attempting this.

Good link. I have been looking at the Ostar LEDs. The Luminus ones are 2500 lumens.

A pretty penny though I just need to get me a decent DLP projector to play with :)

Whats a good place to look for a high power LED in the states?

I'm interested as well. I have an Eiki XGA lcd I'm waiting to gut once a light source is found

mouser, digikey, cutter (australia) have what you're looking for. You would probably want a light engine or module if you want an easier method. Alternatively you could use a lot of individual high-power LEDs (or some Cree MC-Es).

How will you power it? How will you cool it? You need an adequate LED driver (current regulated is better than voltage regulated for LEDs) and a pretty big heatsink if you're going with really high powered modules (even with a fan you will need a heatsink).

What I want to use is something like this: http://www.led1.de/shop/index.php?cName=osram-power-leds-osram-ostar-c-128_184_185 but I was wondering if I could find it in the states if it would be a little less $$. I was going to install it in the old lighting housing on a heatsink and get a pack to power it. I already modded my infocus to stay on with no bulb.

Can anyone comment how is watching movie on p400? I briefly used Mitsubishi PK-20 a year ago and it was horrible on my eyes... I usually watch movies with some light on the background because complete darkness hurts my eyes.

Well digikey has:

I'm sure mouser has something similar but from a different company. Future Electronics is worth checking as well, but digikey/mouser/future tend to be a PITA to navigate unless you know what you want (exactly). cutter is pretty well known on a flashlight forum, most people even if they're in the US get their Crees from there, their site is pretty simple too, check it out they might have something better. For example one of these loaded with Q5 or R2 LEDs:

Everlite LEDs (Their site is down atm)

http://www.everlite.cc

They have some 30watt and 50watt LEDs for resonable prices. Not Drivers available from them for the 50watt LEDs yet. Have been talking to the rep. Looking at 3000-4000 lumens from a single 50Watt at 6000 typical kelvin.

Mod thoughts

The Viewsonic PJL855 I have that is modded without the ballast and lamp is a 3LCD version. These have quite neat optics. I might opt to making a new housing for it and putting 3 x 50 Watt LEDs and a small lense behind each filament instead of splitting 3 ways from 1 source ;) This will be an input of about 10000-12000 lumens.

Awesome, go for it! :) You'll want to make sure it's not too hot near the lcd panels and that each LED is outputting the same amount of light.

I use my p400 everyday, its has replaced my 50" plasma. I have a 110" high power screen. Its awesome at night, movies look pretty damn good. The contrast is good.

Without screenshots we have no way of knowing if you really own a high power. :D :p

Thanks for your comments!

have you tried PK-20? Also, is P400 watchable with 60 watt bulb on the background?

Why can't anyone make a descent LED 720p projector?

Here is one quick shot, I need to learn how to use my D60.

Roadhouse! :D

can someone confirm if the p400 has an internal or external battery like the earlier model did? I have looked and can not seem to find this information.

The user reviews I've seen say it's external.

I have seen reviews saying both external and internal which causes confusion. Also on the samsung product page and user manual it does mention a battery nor can i find a battery product listed. That in combination with the user in this thread using a tekkeon external battery to power the projecter makes me wonder if there is any battery solution available for this unit aside from 3rd party.

60watt LED Driver and 50Watt LED have been paid for.

LED is 3800 lumens @ 50watts or 76 Lumens per watt.

I should be able to fit the driver in place of the old Phillips ballast I removed. This should be pretty wicked.

Neat, looking forward to pictures. I'm pretty sure this is similar to the Samsung P400. Did you order this from overseas?

Hey, man, you have 4 posts ;)

Hey folks.

I find the P400B interesting, but there's one thing that troubles me (apart from the lousy resolution): is the cooling fan really noticeable noisy - compared to, say, an average laptop in its idle state?

This bit is from Trustedreviews'... review.

...we were quite happy to watch a film on the SP-P400B. Or rather, we would have been had the cooling fan not been quite so loud.

Given the SP-P400B's mainly business focus, we can understand that silence isn't going to be its first priority. But to not even have any sort of quiet mode - even if it meant reducing the brightness of the lamp - is rather frustrating. Sure, if you turn your sound system up and watch an action-packed film with an appropriately loud soundtrack, you probably won't mind, but if you really want to lose yourself in the home cinema experience this projector isn't for you anyway.

I can't post URL's yet, but there's also a short video review of it on TR. Gives some idea how it handles brightness-wise.

edit:

Anyone? :(

I bought the samsung p400. I don't really like projectors but this one caught my attention due to LED technology and portability.
I will probably receive it on late April. When I receive it, I will post here a high definition video-review.

I think my new Pelican 7060 flashlight uses this type of led, I think it's called phlatlight? All I can say is it's so bright I'm too frightened to look into it directly. Also it's the whitest light I've ever seen from a flashlight. I found this video on it. http://www.pelican.com/lights_detail.php?recordID=7060

Just found this thread... does anyone still have any interest?

This is a project I've been actively (more or less) working on for a few months... bought up all the parts to make a complete "guts" for the 3rd gen model (with a few spare parts).

First comments... I hate losing the "Cinema Smooth" mirror that shifts the entire image vertically 1/2 pixel, to fill-in the inter-pixel gaps... it really does work.

To retain this "moving mirror", you have to retain a folded projection path... in fact, the "best case scenario" would be to add a fold, and use all the original optics... just in a slightly different manner.

Currently the image path leaves the DLP chip, goes through the main Lens assy (est. 4-5 elements, with focus), then through a circular cropping aperture (eliminating DLP "off-mode" spill), then bounced off the moving-mirror upwards at about 60°, then through the upper-half of the super-wide-angle lens assembly. This is where it leaves the Light Engine, and 'normally' reflects off the FS mirror, and onto the rear-projection screen.

I've been trying to figure out if it's possible to:
a) measure the original length of the light-path from the primary lens, to the wide-angle lens assy - this needs to be exactly the same post-mod
b) For the moving-mirror - move it closer to the primary lens assy, and change the reflected angle to 45° -
c) bounce image up to an additional small fixed 45° FS-mirror, reverting the light path back to the original direction as when it exited the DLP/main lens
d) remove shield from original wide-angle lens, and use it in a more traditional (not so much image shift) mode, but yet allow some image shift for a downward throw.

The goal is to place the projector (in it's new enclosure) flush with the ceiling, about 24" in front of the screen... whatever distance it takes to fill the screen (120" in my case)

Now... about brightness... I will likely need to swap out my existing Da-Lite Cinema Grey for a gain-type screen... the room allows for a narrower viewing angle, so I'm good there.

Preliminary tests at full-white show around 300-350 ANSI (9-point) lumens.

Not enough you say?... I think it is... the contrast in this thing is wonderful, and the saturation is incredible. My HT room (basement) has excellent ambient light control, so with full lights out, it looks absolutely great.

Alternative plan - use a different lens altogether. I bought a 'surplus' lens from a Runco 720p DLP projector, but it has too small a glass diameter (and "f-stop") for my flavor.... and not enough zoom range at the "Wide" end. I've not spent enough time with that lens yet though. First test with it gave only around 250 ANSI lumens under the same conditions.

With this "alternative lens" method, you lose the "Cinema Smooth" moving-mirror... so you will see some SDE... and the Samsung DLP pixels are rotated 45°... like a diamond... I had never heard of this DLP style before... maybe it's a custom for Samsung to take advantage of the 'moving-mirror' smoothing.

BTW - I have tried the original lens both with & without the Cinema Smoothing ("SP Actuator" in service menu) - and though the effect is not "huge"... even on my 120" screen, it's nice... but I seem to always be looking for nits to pick.

I need to learn more about the service menu - I'm not sure my LED's are cranked up 'all the way' - not going to mess with them until I learn. May be some mode I should be in to get maximum color correct brightness... but I tend to think the Test Patterns in the service menu would be at full brightness.

About "wobbulation"... can anyone verifiably confirm these 3rd gen models use this?? In my estimation... they don't. Maybe I'll find something in the service manual that indicates otherwise... but nothing yet... it seems to be full HD, with pixels rotated 45° from what I'd consider 'normal'.

Anyone with questions or comments, feel free!
