MrWigggles I can't believe you are using the terms 'bob' and 'bobbing'. It makes me ill to hear/read this horrible computer terminology applied to video.

Is 'field interpolation' or just 'interpolation' so hard to write?

On lamp,

We always work closely with lamp provider to get the most recent technology. This kind of ultra high pressure lamp has its strength and weakness (like all technology), lamp provider is working to improve their known weakness continuously.

On image processing,

Yes, on page 1, I've stated HD81 is using an external video scalar box, powered by Gennum VXP technology. With one search into Gennum page, one can find the following infos:
Gennum company overall
VXP processing

Yes, it has true 1080i to 1080p motion adaptive de-interlacing with film modes (3-2 and 2-2) for SD and HD inputs. The scalar box simply processes all input and outputs a 1080p signal to projector for display.

Tz, you think Wing can bring a couple back with him? The HD81 is going to be my next and final purchase I hope. At CES we were talking a possible March shipment, things going ok, will it happen?

Sorry about the bulb Frenzy, a couple of bad bulbs now we all want them to stay hot for 3,000 hrs . Most understand typical bulb fading.
Keep working

Bring me back one also

I was using the term already used by another poster, but "bob" is not a bad term at all.

The only problem with the term is that it refers back to the time of simple line doublers where lines were repeated with no smoothing thus creating a very visible up and down "bobbing" of the image.

Now a days, the action of bobbing from 480i to 480p or 1080i to 1080p should and almost always has some form of vertical interpolation. This is why I actually prefer the term "interpolated-bob" but I might be the only one using it. The visible "bobbing" from a interoplated-bobbed images are not nearly as pronounced.

Tom -
I'm not really part of the bulb frenzy and I completely understand bulb fading. Typical bulb fading is fine, and in fact, that is what I hope we can expect with this projector. I raise the question because now seems like a better time for Optoma to address the issue rather then after the HD-81 ships in quantity.
post #517 of 4811
Come on now Tom just a couple? I hope the next projector you get has a rash of lamp problems just to make you know how it feels. I have been reading your post ever since you have had your Sharp. And besides the problem you have had with your HT1000 bulb crazing, you have been dam lucky. So you should not make a joke out of us having problems. Now if this were a thread about Infocus lamps you would be all over it. I never wish nobody any bad luck but this case I do. Maybe then you will understand where the people that are having problems with their H series projectors are coming from. Yes it is a big deal to me. Are you sure that you don't have stock in Optoma.

Just being the voice of reason. It's a bulb, we have to live with it.

Take it to the bulb thread pls.

That's Darin, actually I'm pretty frugal. My friends in Milpitas send me models to test which go back but the 1080p model, I buy!

Specially after viewing it setup right in a dark room and hugh screen. I like the two piece idea for the one cable. Plus Gennum scaler deinterlacing, can't wait to run tests on it. I wasn't dreaming there was some talk about March which is now.
post #521 of 4811
I'm sure someone has posted this, but >500 is too much. What is the throw ratio for this unit?
post #522 of 4811
From the very first post in this thread...

6. The throw ratio is about 1.8 to 2.2:1 (about), the offset is 27% (of vertical height), ...

Thanks Scott. I read that how many weeks ago, but forgot where it was. The cut sheets I have from the show don't have these specs. I've since pre-sold one and we're building the theater around it now, and I need to place the AC and HDMI. Thanks again.
post #524 of 4811
Some Internet stores are taking pre-orders already on this unit. At least one store is posting a price. Looks affordable. Wish it had a shorter throw, however.

Wow. I think I found the site you are referring to. Yes, that price would definitely qualify as "affordable"!!! A good 2k less than what the Ruby streets for.
post #526 of 4811
I think if that was the actual price we would all buy one tomorrow. I know I would.
post #527 of 4811
I'm curious as to where the lens is situated on the projector. Previous Optoma's it was off to one side, making installation easy for me and my cathedral ceiling where I could mount it off center (but get the lens centered).

Does anyone have a picture of the H81 or know if the lens will be off or on-center?

The image it puts out is even prettier. Check this thread for more pics and screenshots from CES.

where are they doing pre-sales on the internet?
post #532 of 4811
If this is the same internet vendor that was discussed a while back, you guys might want to at least do a basic check on them before committing any money. Go to reselerratings.com and enter the vendor's name. If it is the same one I checked a few days back you will find out they are at best questionable and at worse dishonest.

What is it they say about a fool and his money?

Good luck.

Yeah, after looking closer I agree. Their shipping charges are exhorbitant too.

My distributor told me today that the H81 will not be shipping until June. Has anyone heard anything different (more positive)?

Almost the middle of summer!, well that's good and bad news for me.

Obviously bad that I will have to wait much longer to see (enjoy) one of these in my own HT, but...

Good because, the more time for all of the distributors (maybe even a certain 'big box wholesaler' here in Canada) to load up on these and more time for me to get the HT reno underway!

Besides, it will summer, time to be outside!

If the Gennum processor receives an HDMI input from a DVD player, does anyone know what are the audio output options available?

My planned A/V receiver does NOT have an HDMI input.

Thanks - you have better eyes than I do. Do you know of any cable/switch that converts the audio portion of HDMI to optical? I have my heart set on the NAD 773 A/V receiver, but it doesn't have an HDMI input.

Ben,

That's what I've heard too I wish it were sooner as I would like to see some reviews and comparisons to the Ruby.

On a side note, are you by chance any relation to the original "Forrest Park or Snellville, GA Harpers"?

My father's entire side of the family lives in and around Atlanta and I go there often to visit the southern side of the family!!! Stone Mountain Rocks!!! My uncle by the same name lives near Alpharetta and owns a car dealership called Harper Motors SE of Atlanta off of I20.

Maybe we're long lost cousins!?!?!?

Won't the increased resolution of 1080p be readily noticeable at the close viewing distances that are typical with front projection? I come from a background in RPTV, and there it is 'conventional wisdom' that the increased resolution of 1080p is readily observed if one sits as close as 1.5 x the screen diagonal. With FP, it seems that sitting at ~ 1.5 x the screen WIDTH (= 1.3 x screen diagonal) is very common, so wouldn't 1080p be a significant enhancement (whereas it really isn't if one sits 12 ft away from a 50" RPTV)?
