Calling you out...who owns a LED projector? - Page 2

post #31 of 99
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?

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

*edit* found a recent review from PcMag for the Samsung p400

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.

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.

What do you mean by lag?

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

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,

what's the largest image size you can get with this little projector?

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 have roomates that do nothing)

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

Being an owner of Dell M109 you can put your opinion and pics in this thread:
Calling you out...who owns a LED projector?

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 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 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
post #60 of 99
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"?
