OWNERS thread for Mitsubishi HC7800 - Page 3

What are people's thought on the 2D to 3D function in the 7800D so far? Would you prefer using this conversion over straight 2D presentation?

Have any of the owners done any gaming on this? I am curious about the lag time. It appears the Benq 7000, even though DLP is not the greatest.

Thanks,

Lowell

Hi everyone,

here is my complete test of the Mitsubishi HC7800.

http://www.homecinema-fr.com/forum/v...761#p176568761

Sorry, this is in french langage but i can translate for those who will ask.

Regards,

Patrice.

Thanks for posting.
Here is the MS Bing translation. Just scroll down a bit:

Someone on the french forum is also raising this softness issue. See translation link above:
"I just the mitsu has an image too soft for a dlp and lack of brightness in low light duty to high lamp"
Not bad having consistent reports from two continents and three countries!

From the review it seemed that the reviewer was very impressed with the 2D to 3D conversion. This is what PC was originally claiming late last summer when it did its preview. Now PC is saying the conversion is not as good as the Panny's. What gives?

Maybe the pana has the best convertion system but the mitsubishi convertion is excellent too.

It is not as noticeable from viewing position, but it definitely makes the overall image feel soft. This happens with both my sources, my htpc and ps3 as bluray player both through HDMI. I am really curious if this was what projector central's pre-production unit was suffering from?


I'm looking forward to more owners posting their impressions in here. I wish at this point I could take those sharpness comments back. With more testing, I have found that the patterns are perfect and pixel matched when native in both 16:9 and 2.35:1. It is only when using the aspect scaling method that they go out a bit, and since the image is scaled at that point, I don't think it's possible to have them pixel mapped in the first place. Again, I would like to state that after more viewing, that even when scaled and watching a video, it is imperceivable. Until a 'pro' can state what is going on, I wouldn't take the Mits out of the running.....go see it for yourself when/if you can.


Thank you very much for your full review Patrice. I was following your thread for quite some time. Eventually I will have to have my PJ calibrated (or more likely learn to do it myself), but in the meantime for the heck of it, I plugged your white balance and CMS numbers in and they look great. Everything is popping on the screen!! I love the DLP picture more and more every day.

I will watch some test material before the end of the week regarding 2D to 3D conversion and post my impressions.

I know the importance of going to view products in person as too many members here post without first-hand knowledge. Then there is the issue of being steered. I try to post what other owners or reviewers have noticed. You are to be commended for updating your position to the more accurate. Thanks!

Buying a projector is like buying a car. You can spend weeks becoming dazed and confused by only reading about it. Or just a ten minutes test drive to determine if its for you.

I am very interested in evaluating the 7800 (the only new DLP with 3D with the DC3) and went out for a day hopping from dealer to dealer. Some dealers had the 7800 in the warehouse but not on display. They were steering customers toward other products. I have the funds and want to support a local dealer, but no dice.

So even if you try like I did, you will frequently fail. There is also rather extreme pressure from sales people who I frequently end up teaching. Then there was one who told me he needed a sale cause he had a family to feed.

There is a heavy bias toward Sony and JVC with Epson running third. One dealer had the Sharp 17000. DLP seems rather confined to primarily to AVS and Amazon. It used to be the opposite. Dealers love the $8K projectors and are none to impressed when you show severe ghosting or gaudy color.

There is the Optoma HD83 too with DC3.

The picuture looks good. Very similar to the shots in the RS55/X70 owners thread. I am glad you like the projector, I have been looking at this or the HC4000 for my first one. I am still debating on the whole 3D thing. I have to say, the glasses for the 7800 have to be my least favorite of all I have seen. What are they like, they look heavy?

When you say good for one movie is that due to comfort or eye fatigue?

Have you tried the glasses on anyone that wears perscription glasses?

This is unbearable! You need to start a thread and write 50 pages
Or just state the simple truth that the Mitsubishi is a class act with the best 3D performance. It's 2D is more three dimensional than the others no doubt because of its pixel speed, superior processing and glass optics*. Somebody was talking about full 1080p motion clarity too.
I really like the 4000 and it has many fans throughout the world (I've read the foreign forums). That nasty warehouse Co***o even sells them now...

My only question is how does the 2D performance of the 4000 compare to the 2D performance of the 7800?
Maybe I'll find out sometime.

Have you noticed if there any flicker to the image?

Is there any mis-convergence or focus issues across the screen?

Can you clearly see the pixels with a paused bright picture?

*One "steerer" in the <$3K forum said you must spend $10K for this!

I have been using the Mitsubishi HC900 DLP projector since 2005 in my home theatre of 21' long x 12' wide x 9.5' high, and recently upgraded to 9.1 audio with Denon 4311 and OPPO 95. I use the DIY Wilsonart Designer White 5' x 12' *laminate of gain 1.3 as my screen. It is time to get me a new Christmas and New Year present with wife's approval ;-)

Having read thru all the related posts in the AVS forum concerning the new crop of projectors, basically my choices fall on the few named consumer brands with 3D support:

Panasonic PT AE7000 - ? flickering issue
Epson EH-TW9000 / Powerlite Pro Cinema 6010 - no FRC in 3D and input lag
JVC DLA RS 45 / X30 - best 2D but relatively poor 3D with ghosting
Mitsubishi HC7800 - ? Soft picture as noted by some
BenQ W7000 - unstable current firmware
Sony HW30 - good compromise between 2D & 3D but beyond my budget

I was swayed towards the Epson (brightness and black level) and the Mitsubishi (DLP sharpness & 3D performance). Finally I settle on the 7800 after roaming the forum for few months since I am not sensitive to rainbow effect.

The image is much sharper and brighter than my 900 though the lamp life of the later is reaching its end. As pointed out by other members here, the black isn't that good and you can still see some dark grey in pure black but that doesn't deter my enjoyment with films. Another thing is the rainbow effect that seems to be more evident than my old 900. It is more discernible if I try hard to find it but generally not obvious to me and my wife during a movie watching. The 3D effect is really marvelous but does suffer from a subjective significant drop in brightness, requiring bolstering with the specific 3D mode enhancement. The glasses use button battery and claimed to last 70 hrs but are a bit too heavy on my spectacles.

Nevertheless, I am quite satisfied with its overall performance, especially when it is selling US$900 less than the Sony. One can never have a perfect projector, considering the budget and my aging eyes & ears that made the delta gain in higher performance not cost effective to me ;-)

Just my bit of sharing and confirmation of the general opinions as raised by others here.

I was at my wifes co-workers place last night for a new years party and he just had his 7800 installed a few days before. I though it looked great and he had 20 hours on the bulb.
The 3D was ok on avatar, it was very dim in his HT but the rainbow effect was horrible for me. I could only stand it for a few minutes at a time. I've known that I can see the DLP rainbows, as I used to have a samsung 67" led DLP a few years ago. This projector took the rainbows to the max for me. It made me actually feel sick. Not sure why this one projector would do this and the others I've seen no but it was what it was.
Kinda sucks that I'll never be able to have a single chip DLP but whatcha gonna do right? lol

I imagine a 6x wheel would not bother you nearly as much.

thanks for the feedback on the RBE. The W7000 @ 6x was just barely outside my threshold, but could still catch it hear and there.

Was he using the Mitsubishi glasses? how are they?

The Optoma HD83 tested poorly at both Trusted Reviews and this French site (Kraine). In fact was rated lower than the Optoma HD33. Its as if the near black image data was simply discarded. I'm sure just a firmware upgrade will fix it!

Instead the Acer 9500 offers the most bang-for-the-buck with a dynamic iris which helps out on the blacks.
http://www.microsofttranslator.com/b...H9500BD-6.html
However the Acer's brightness comes at the expense of accurate color. This is an old DLP data projector trick, to add a white segment into the color wheel. So its not going to satisfy those who demand refined color.

The more expensive BenQ 7000 needs to get the basic's down before releasing a product.

I'd like to point out that black levels can automatically be set incorrectly when components boot, especially for htpc's. The best method is to have the display and receiver on and switched correctly. Then when the HDMI source boots and communicates with the HDMI display, the correct black level/range will be set. If there are any doubts then reboot the PC.

He had 2 pairs of the mits ones and 6 pairs of some other brand (I never saw them though). I only had the mits ones on. They were not very comfortable, though for 1 movie, I'm sure they would be fine.

His last projector was a BenQ of some kind but he didn't know the model. All the audio was in wall stuff and to be honest, it sounded pretty crappy for such a nice theater and home. His screen was some sort of pull down one 1.3 gain and it was wavy in spots and not very straight. The guy who did the install used pretty crappy equipment, although the wiring in-wall and ceiling jobs was really nicely done. I know the room was at least 40K to build and he's got "maybe" 5-6K worth of gear and that includes the projector.

He's happy with it, so thats all that matters, at least it wasn't bose or something like that.

3 chip DLP don't have wheels right? I think a lot of the problem is once I see the rainbow, it's ALL i can see lol. Though for almost a year with my LED DLP, I did get used to it but always knew it was there.

Somehow I wonder whether the 7 segment RGBWRGB 4x wheel in the HC 900 is better than the 6 segment RGBRGB 4x wheel in HC 7800 ??

Interesting...I watched a 7800 at CEDIA for quite some time trying to see rainbow and I could not. I am or thought I was very sensitive, usually if I move my head or eyes quickly up, down and sideways it will rear its ugly head. The room was not totally dark and had another Mitsubishi SXRD running next to it...Perhaps that’s why?

I could even see slight rainbows on some of the high end single chip DPI projectors at CEDIA. I can see it badly on my Acer 5360 in 2D and 3D to the point of causing headaches if I'm tired. Although I really have watched much 2D on it, I still use my 15 year old CRT projector for 2D. Knowing that you can even see RBE on a 6X wheel makes me think a LCOS or LED might be my only option when the 3 eyed monster dies. I like the pop of a DLP but can’t handle the RBE and the way it sounds the Epson 5010 might be a nice alternative. I’m going on 10 years for the same projector and want to make the right choice on the next one.

I have mitsubishi HC7800B in test. I can compare it directly with Acer H9500BD, here you can see the differences. (ghosting comparaison for exemple)

http://www.cinetson.org/phpBB3/proje...33291-630.html

My full review about the HC7800BD will be online this Thursday

Is there any ghosting here? If there is my monitor does not show it!

On the bottom of the R (Right channel) you can see a trace of the L from the left channel
