This HD80 sounds like a pretty good unit for the money. I just wish my basement theater had a higher ceiling. I don't even think with tilting it slightly I could make up for the 7.5' ceiling. I need the image to be at least 3' off the floor with a 92" screen.

Again these manufactures need to at least have vertical lens-shift if they want their units to appeal to a wider range of possible customers. Sharp did it before on their DT200, DT300, XVZ90 and XVZ200 that were lower priced DLPs at the time.

I would be willing to pay a reasonable premium for lens-shift.

So is it DC2 or DC3?

In the manual, it is identified as neither, just a 0.95" DLP chip. The projector displays excellent blacks, whatever it has.

Hopefully HD-80 doesn´t have the reability issues that some HD-81 units had/still have.

Liked the HD80 better, that says alot.

Has anyone else seen the rs1 and the H80?

I'd be interested to know in what ways the picture differs, which is stronger in certain areas etc.

I think this is the same chip I already have the DC3 - so Tom are the black levels the same then as what I already have on the HD78DC3?

Anything to be gained from the iris as far as black levels?

Would the HD80 be a good upgrade coming out of my HD78DC3? I have been very happy with the HD78DC3, but would love more "dots".

Where can I get a good idea of the current value or lack of value in reselling my H78 should I decide to upgrade?

So, this unit might actually look better to people than the RS1? That's interesting.

Bear in mind that these are different technologies. So it depends on what people's priorities are. For example, if one likes a sharp picture, DLP scores lots of points in that area.

The current value of 720p projectors is falling fast. I am wanting a new projector and at first I was going to get a DC3 720p after seeing the pricedrops but I have decided to wait and get a HD80. I have a 1st generation 720p DLP that I am selling to a friend and I am lucky he doesn't know about avsforum or he definitely wouldn't buy my projector anymore.

Well, I'll just say that someone had an H78 for sale here at AVSForum for $850 or best offer with 250 hours on the lamp and no takers. I was considering it, but I seem to recall reading something about lamp problems, so I'm on the fence.

So I setup the HD80 saturday night and watched two HD DVDs (Breach and King Kong).

Its current setup is less than ideal, as it's temporarily projecting on a bare wall. The resolution, contrast, and detail were great, but the image was slightly washed out (almost like glare).

Just to elaborate on the setting: The room has windows on two sides (although I was viewing at night), and the projector's about 18" off the floor and about 14' back from the wall. I was projecting the image as large as possible from this distance.

Is the washed out image a result of projecting on a bare wall, or is it a result of the light from the projector reflecting off of the windows and onto the wall?

I'm happy with this temporary configuration; I just wanted to verify this issue is a direct result of the setup and not a short-coming of the HD80.

Must not be a friend worth keeping? If I sell my H79 to a friend it will be with full disclosure. If I sell on Craigs List, Buyer Beware.

You shoot it on black wall or white wall? Your room is it light control? Have you done any calibration?

Professional Reviews (WSR, UltimateAvMag) of the HD80's big brother, the HD81 measured very, very poor on/off CR.

Something to keep in mind.

Very good black level on the HD80, just ask some of the new owners here.

Measurements, 49ft candles in brightess mode, 3100.1 CR iris fully closed, 2930.1 iris at 12 stop, measured with sensor close to the lens for accuracy. Fully close Iris can take the Ftc's down to 15 ft candles.

Ric4Nav, it looks like a new firmware is coming later this week, 1.9 that will let you force 24hz at 1080p.

I have found the HD80 anything but washed out. I would suspect it's your room conditions. I mean, anything's possible, you could have a defective projector, but mine puts out very nice blacks with excellent contrast. My projector height and throw are almost identical to yours, except I am projecting onto a Da-Lite HC matte white 106" screen, with excellent light control (at night). You might check your iris and brightness (black level) settings. I believe my iris is at 10 and brightness around 50. It may just be your wall. Check for any stray light falling on the picture area too.

Two weeks ago I saw the HC3100 projector (3000:1 CR) at a friends house, where the projection room is white. The image at brighter scenes looked washed out. The image from the AE900 (700:1 CR) looked much more punchy to my eyes in the same bright scenes, in a room with dark walls.

I bought the HD80 and realized It had no "real" lens shift and "weak" zoom. So the only way to get it to work was to place it on the ceiling at least 8-9 feet high and about 15 feet back to get a picture large enough to fill my 125" screen. Since I am replacing a 720p LCD projector, this was a "no can do", so I returned it and got the Epson Powerlite Home Cinema 1080. So far I have no complaints and the picture is fantastic. So if any of you are considering to buy this, just make sure your room is big enough and the ceiling is high enough to mount this.

The HD80 actually does have a zoom... It helps a little but probably not enough for a huge screen. Mine is 100".

If you mount it right you will get an awesome picture. Especially playing games on xbox 360 like gears of war. This projector had very good black levels. The problem is my room is already setup so I can only place the projector on a shelf 8 foot high behind my seating. And the HD80 was not flexible at all for this kind of placement.

This projector vents a lot of heat. I personally would not place it on a shelf right against a wall unless there is very good ventilation. In my case, it is mounted in an open area and the hot air does not get drawn back into the air intake.

As far as PQ, it does have great black levels. I have white walls and a High Power Da-Lite screen. I do not see an haze or veil (I would not use TV mode, which is overly bright. Also turn off edge enhancement - it works in HD mode. For fun, turn it to the max and you will see some interesting changes to the picture )

Agreed, you cannot mount it on a shelf because my unit kept overheating.

Well, definitely a friend worth keeping but its hard to think you are ripping someone off when asking $1800 for a Marantz VP-12S1 that retailed for $12,500. I bought mine from Japan and paid half of retail. I think my projector has been selling used for around $1000-$1300. So, I'm not trying to sell him an Optoma HD70 for $1800.

Sounds like you are overcharging your friend then by at least $500. Not cool to do to a friend. If your friend ever finds out you probably won't be on speaking terms afterwards.

Your friend probably trusts you. Just an example of why friends should never do business together.

I got a demo of one of these. I'd like to give it a try. I just can't get 1080p LCD to work well for me at 106" 1.1 gain screen size. I had a light canon SP5000 before I started on my 1080p projector quests. I could try changing screens, but that is a bit of a PITA for me, I'd like to avoid if at all possible.


I just want to be clear here.

I have an 8' ceiling. I can get a flush mount and I can tilt the projector up a little, use keystoning and I get a 16:9 screen about centered within the 8' I have to work with? I was going to throw at around 17'... As stated 1.1 gain screen.



Any suggestions welcome.

I guess I am not listing all of the specifics which I should do. I did price him this projector 9 months ago at $1800 which it was bringing then. Then recently when he told me he wanted it I offered him my 106" High Power screen to go with it.

Enough about this...back to talking about the HD80.
