2011 Mitsubishi 3D DLP Owners Thread (740/840 series) - Page 8

so has anyone used the new 840 for gaming and if so how does the 120hz handle the judder.most of my time will be gaming and blue rays.I just return my samsung pn64d8000 it was a nice tv but imo not the best for my needs.This tv in 73" is looking good but i need some help you see no stores within 75 miles has this tv on display so i will be shooting in the dark. how clear is the picture my old samsung dlp looked good but that was seven years ago so if anyone can compare this tv to a top end lcd or plasma and let me know that would be great.clear contrast screen is it only on the 82" or is it also on the 73" and one last thing my stand is 20" tall is this to tall for the 73".
thanks for the help guys.

Looked like a good deal so I went to their web site and they don't list any mitsubishi tv's much less the 82840. What's up?

They had just happened yo get one in for display and I told them I was waiting for a deal I had got online to buy it for the same price. Guy went over and talked with the manager and sold it to me for same price. I think business has been really slow and any business was good business. Two more days till delivery.

Unless you were comparing two calibrated TVs in a controlled environment showing the same source material, that isn't a fair assessment. I seriously doubt there is a night/day difference when both are properly calibrated.

I would tend to agree and will to go as far as saying each set has it's advantages and disadvantages, there is nothing about the new line except the addition on the larger screen size of the 92 and clear contrast screen for the 840 82' and 92' only thing a comparison may reveal is clear screen on or clear screen off . The other features have nothing to do with the PQ itself! Although 3 chips would have been a true game changer

Has anyone found the glossy screen a problem? I can clearly see reflections and glare unless the room is COMPLETELY dark.

I just received my 73840 yesterday. It does not have the clear constrast screen in case anyone was still in doubt. I kind of wish I had gone with the 82" now. But I couldn't justify the extra $1,350 before tax. I find the pictures to be pretty good considering the size of the screen. I haven't adjusted any settings yet other than bringing down the contrast.

I need some help, I'm new to DLP and 3D. I ordered a pair of Ultimate 3D Heaven Ultra Clear Rechargeable Samsung Glasses from Amazon. The description said they work with Mitsubishi as well. I can't sync the glasses to the TV. Any suggestions as to which glasses I should get or what I need to do to get 3D. I liked the newer models because of the internal IR emitter.

Could you be a bit more specific. As I understand it everything (including the bulb, TI chip, etc) is the same between the two except for the clear contrast screen. Anyone else had the opportunity to view both?

I'd be interested how you wind up disposing of the Mits 65". I've got a 73" that has developed white spots after I changed the bulb and may need to be disposed of soon. Don't know what I am going to do with mine.

so the 73" does not look as good as the 82" because the screen is not the clear contrast is that what you are saying.and have you played any games or played blue rays on it yet.how does it compare in PQ to a plasma or lcd.Iwant to order the 73" but not sure now. please post some pictures if you cant.thanks

Won't have my 82740 for a few weeks but was wondering how are people finding dvds to look on their screens? I have a couple hundred blus biut a couple thousand dvds...I'm not too hard to please visually...thinking of making it so I can move couch back for dvds, fwd for HD cable and blus...another question, what is a good 3D player to buy? Glasses? Any ideas?

That's easy. I own a big fire pit on one of our farms.

Unfortunately, I live in a condo without a fire pit.

HI ALL. I Have gotten 73640 a week ago. I am impressed and happy. Very crisp an clear. Some to no blocking, 3d is crazy. Yes the pic do dims but it no worse than at the theater. The detail is good also; TRON was very impressive. I thought it would lose some, but i did not notice any loss. But it is my opinion. One thing I notice from other post is that the larger model have a SHINY screens, mine has that matte finish. you get a itty bitty demo of it here:http://www.youtube.com/user/GEN7V6PILOT?feature=mhsn don't mind the announcer; he was like a little kid with new toys. an the couple of secounds was a BR.

If I understand this correctly, all 3D movies are currently 720p and nothing is available in 1080p, correct?

No. The vast majority of 3D blu-rays are 1080p. Though a rear projection DLP will only display 1080x960 per eye in 3D mode.

Hopefully these photos will satiate the masses for a while. I just took delivery of my new WD-73840 thanks to our sponsor Cleveland Plasma. The set is a replacement for my WD-52725 that refused to recover from a second bout of the dreaded green flashies. The set is sitting atop an existing BDI Avion Series II cabinet that happens to match the width exactly. In the pictures below there is a large west-facing patio door and some of the pictures have the shades open, and others closed (I note which). The photos were taken around 10amCST in Dallas so while not direct sunlight, it's still very very bright (and hot).



Comments so far:

• Screen is fairly matte and does pretty well in sun unless you're at decently off viewing angle.
• Viewing angles are pretty good (better than the WD-52725 it replaced).
• The input connections are mounted to a portion of the TV that concaves in towards the front which means you can push the TV completely flat against the wall without needing to allow extra room for the cables (so even though it's about as thick as my old set was, it sits much closer to the wall).
• I may be the only one but I miss NetCommand.

nice pics! How deep is this thing, like 18"?

73840 is 19" deep and you can put it flush against the wall. Earlier models you couldn't so it was 19" + how ever much you could squish your cables.

That is incorrect. See the link in my signature.

I've seen it. I don't agree.

how tall is your stand.my stand is 20" is this to tall for the wd73840.how is the PQ for bluerays or games.Iwill be ordering my 840 tonight and really looking forward to it.

Somehow, I knew you wouldn't.

Square pixel DMD displays would be 960 x 1080 lines of mirrors and wobulated to form 1920 x 1080. Also, 960 x 1080 would be line interleaved, not checkerboard.

The TV can't display 960 x 1080 per eye, because the mirrors of the DMD are not square and are not arranged that way. The mirrors are diamond shaped, oversized, and arranged in a checkerboard pattern with 540 row pairs and 960 column pairs.

It's just a matter of counting the lines, and the mirrors in each line.

Because of the diamond shapes of the mirrors, there are 1920 vertical lines of 540 mirrors, and 1080 horizontal lines of 960 mirrors. Count them.

Light from the mirrors is projected at twice the pixel size, and because of the diamond shapes, the diamonds interleave with each other, making 1920 x 1080 lines with half the mirrors (and half the information). Again, count them.

I saw the 92840 shown at a convention in a very bright room with no cover (light directly showing into the TV) and it still looked amazing!

the picture was bright, crisp and apparent.

I imagine if in your home it would be zero problem with reflections.

Thanks for the cool pictures. That's a nice set-up you got there.
We got the call today that our 73740 will be delivered Wednesday, we can't wait......

the bad news is that mitsubishi changed their emitter code from previous years to a new code this year. that means that glasses that worked on last years TVs will not work on this years TVs without using a seperate IR emitter.

I think you can buy those used on ebay. it should be cheap. just make sure to disable the internal emitter if you use the external one.

contact one of those TV service parts salvaging companies. I wonder if they would buy it from you?

interesting, but what information do you have that shows the mirrors are not square shaped?

What is on top of the tv? Is it the ir 3D emitter or what?

Understood. There is no "conventional" way to describe it. We call it 960x1080 to put it inter terms that we can understand relative to the more typical orthogonal arrangement. It could just as easily be called 1920x540. It just depends on whether you to count by shifting every other column, or every other row.

The "row pairs" and "column pairs" that TI likes to describe them as are misleading. That results in counting pixels twice.


Agreed.


Yes, and if you take a pen and "check off" each pixel as you count it, you will see that you would be attempting to count some pixels "twice" if you count them that way.


Yes, but only after two sub-frames are projected. In 3D mode, each eye only sees every other sub-frame. Each sub-frame only contains 1,036,800 pixels.... you can call that frame 960x1080, or 1920x540, or however you want to define it dimensionally. But the end result is it's only about 1MP.

Or... the short answer is: I can see it. The loss in resolution is very apparent if you sit close enough. Put up an image with very fine detail. If you have an HTPC, any windows screen is a good source, since much of the text is only 1 pixel wide. Put it in 3D mode, and put on the glasses. All the missing pixels become immediately apparent. Through more typical video content, it's not normally noticeable unless you sit very close. But it's clearly there.


Actually, they are still square shaped, but they are rotated 90°. Some people call a square rotated 90° a diamond, to me a diamond suggests a shape that is taller than it is wide (or vice versa), but for this purpose we'll just consider it semantics. But all you need to do is put on the 3D glasses and look through one eye. This eliminates the overlapping that occurs, so you can clearly see the pixel layout. You will then understand why it's difficult to classify the resolution in a standard "X" by "Y" dimension. Doing so tends to cause people to count some of the pixels twice.
