I believe the HD65 is only 60HZ and the converter requires 120HZ. We are out of luck it seems for now. Keep watching within a year or so for the HD66 to go on clearance at Best Buy for the same $299 that the HD65 did. I hope anyway. Currently there isn't much content for 3D anyway.

hey guys i am looking to get into projection setups and i was seriously looking into buying this projector. At first i wanted the HD66 until i realized its odd resolution. I found this Online through a reputable company as a refurb for a decent price. But the ? i have is would you trust an manufacture refurbished one?? or if anyone has in idea of where to buy one new at a good price a pm would be greatly appreciated. I DO NOT WANT 3d at the moment as well.

I bought a factory refurbished unit from a Canadian online supplier..
Never had a moments problem with it and it's now on about 1500hrs and still going strong!
The only downside is that you usually only get a 3 months warranty with them..

Guys I hooked my HD65 back up and I noticed the projection is uneven. When I measure the left side of screen top to bottom it's 44 inches. When I measure right side it is only 43 inches. What could cause this. I played with every setting and nothing corrects this.

Sounds like you're projecting at a very slight angle to the screen. If you turn the PJ slightly toward the 43 inch side they will be even. The PJ beam needs to be perpendicular to the screen surface since the HD65 doesn't have lens shift. Of course, then you may have to shift the PJ or screen a little to the left or right to have the image centered.

hi frens i just got this beautiful projector....

i'm gonna mount it on the ceiling but the power cable is so small...

where can i buy a longer power cable about 10 meters...?!?

Thanks
post #2707 of 2880
Monoprice (one of the sponsor's listed above) is excellent.
You can buy a 25 foot power cable, or a longer heavy-gauge extension.
post #2708 of 2880
nomad thanks....

what is a longer heavy-gauge extension.... could you provide a link for that too...?

also how much "awg" should the power cable be ? it a higher number better or is a lower no. better ?!?

thanks pal
post #2709 of 2880
Here is the power cord extension (50 feet if you need something really long):

Here is the replacement power cord (25 feet):

For the AWG -- you want a lower number rather than a higher number. Both of these are 14AWG.

nomad.... thanks a lot pal... ;-)

HD65 or HD20?
For small room, throw and viewing distance 8 ft, screen size is 76". Only watch Blu-ray movies, is 1080p necessary? Thanks!
post #2712 of 2880
I have the hd65 15' back and seating 15' back with 129" screen. everything looks great but that being said the next pj will be 1080p. The closer you are the more likely 1080p will make a difference (relative to screen size of course)

I would probably say with 8' back go with the HD20 unless it's more expensive by a lot. just my .02 as i'm just getting back into HT since the weather is gettin crappier (yay)
post #2713 of 2880
Hi sdmfer

You watching 129' from 15'... Bro don't you find that size to be too big

I tried 120' from 15' and couldn't fit everything in my vision and had to constantly see left to right

What say...?!?
post #2714 of 2880
let me reconfirm my measurments I could be off by a couple feet since I actually move my couch forward and back from time to time.
post #2715 of 2880
My HD 65 screen is 131" but i sit back 19'. its perfect.
post #2716 of 2880
Will I see SDE viewing 8' away from 76" screen with HD65?

ok just double checked the setup as I have it now. Screen size is 126" and seating (eye) distance is 15' 8" away from the screen. it looks great.!! The only thing I'm thinking about doing is lessening (sp) the size of the screen so I have a little more room to place my speakers. my screen wall (iirc) is only 11.5' wide so my front speakers currently sit within my screen wall section that is painted flat black for my boarder. know what I mean dude?
post #2719 of 2880
I have a 106' screen and sit back 11 feet. Suits me just fine, especially for watching sports.
post #2720 of 2880
92" screen, we probably sit about 10 feet away.

No SDE, no issues at all. Just the best picture I've ever had in my entire life.

Just grabbed a HD700X (HD65 Clone) from the Amazon deal earlier this week and a 84" Elite VMAX2 screen for my basement that I am remodeling. I figured it cost me the same amount to grab the HD700X and a screen as a cheap 720P 42" Plasma. I had just started to research projectors and I'm afraid I might have jumped the gun a little bit. My dilemma is, my basement will not be done for months so I really can't set it up and see if it will work or not. I'm concerned that even with the smaller screen I bought, will a HD65/HD700X be able to cope with a fair amount of ambient light? I would say that 65% of the time there will be some light on since it's more of a play room than a dedicated home theater. Should I return it and spend the extra $300 for a HD66 or will I get by with my super cheapo setup?
post #2722 of 2880
I think the question is: why did you buy ANY projector for that environment, not this particular model.

Well you "might" be ok depending on how much actual light there will be. Maybe blinds on the windows turned down a little so there is still some ambient light, just not as much. Either way, if would probably suggest returning the projector and screen until your ready to set it up. If its still months away from being finished, you could always use the cash elsewhere in the room to git'er done. Within "months" Im sure there will be plenty of other deals out there. Not sure what you paid for the projector and screen though. What I would do, but this is just me (and what I would recommend to my friends) is finish the room, then go with a DIY painted wall (found on this site). Set the projector up, get the exact screen size you want, then paint screen and do a border (either fancy with wood for eg or just flat black)

This is what I did and i couldnt be happier. The worst part of the whole HT experience, is with three kids under 4 yrs, I have about 2 hours per week of spare time to drink a case of beer and watch a movie to myself..lol.

I guess I figured for just over $500 for the projector and screen, if I only use it to watch an occasional movie it would be worth it. I'm going to keep the projector and the screen and if we find that it's not bright enough, I'll just pick up a cheapo plasma and wall mount it. When I build the soffit for the electric screen, I'll leave enough clearance for a wall mounted TV behind the screen. The basement itself only has two 17" x 32" windows which will be easy enough to cover. I was just hoping someone could just say it would be OK for occasional viewing with some lights on, say Sunday football with some controlled indoor lighting.

Ive had my HD65 for over two years, and its has had to be returned to Optoma for warranty repair due to a failed cooling fan on two separate occassions. Yesterday, the bulb exploded.

In the meantime, I pulled out my old H30 as a backup whilst I await my new HD65 lamp to arrive.

WOW, this thing blows my HD65 out of the water in terms of light output, contrast and colour - and this is despite its bulb being passed its life expectancy! Even when brand new, my HD65 didnt even come close to the image this old projector puts out, I cant believe it...

When I intially upgraded from my H30 to the HD65, I recall being clearly disheartened with the reduced contrast and colour reproduction but having put the H30 back into service its all coming back just how much better the H30s output is, notwithstanding the limited resolution of course.

The one thing that stuck with me with the HD65 was the terrible discolouration I seen when enabling brilliant colour, or even pushing the contrast up to higher setting. With each step increase in these settings, the whites would have distinct change in hue, from a pink tint, through to green.

My final calibration settings ended up having to have both brightness, contrast, brilliant colour all set to 0 but this still resulted in colour crush, with shades still blending. I found a great test for this via the following test screen, and I would really like to hear how this looks on your HD65:

http://www.lagom.nl/lcd-test/contrast.php

I found that my HD65 would not resolve all of the individual steps in the colour bars until I had set the RGB gain to the following setting:

R: -15
G: -21
B: -17

Having to reduce these values so much resulted in an already dull image to be further dimmed. I tried different inputs (VGA, Component, HDMI etc.) and different video sources and found no difference. My own theory is that the RGBRGB colour wheel in the H30 is far better suited to reproducing strong vibrant colours, and the RGBCYM wheel in the HD65 only seems to help reduce temporal dithering artifacts in dark greys and greens, but at the expense of overall colour reproduction. Either that, or the brilliantcolour implementation is bad.

Has anyone else experienced such colour problems on the HD65? I would like to hear your results on the colour contrast test linked above to see if your HD65 is crushing the colours. I would also like you to test changing contrast and brilliantcolour levels whilst observing if and how your white colour is tinted with a pink or green hue.

Im now considering looking at an alternative DLP with an RGBRGB colour wheel. Would anyone have any suggestions for such a PJ that had a similar offset to the HD65?

EDIT:

Please also try your HD65 in this gradient (banding) test... on my projector there are clear areas which band heavily and have green and pink shades amongst the greys.

http://www.lagom.nl/lcd-test/gradient.php

Again, I would appreciate your feedback on how this looks on your HD65.

I owned an Optoma H31 before getting the HD65. To me it was a very significant improvement not only in resolution.
It is a bright projector and you have to turn down the brightness and color saturation in order to get a great looking natural picture. I agree it took a bit of time to calibrate and I use different settings for different sources (standart DVD, Bluray, TV). I project on a Graywolf II screen which helps with the blacks as well. Very satisfied with picture, brightness, mobility and reliability.

How does your HD65 fare in the image tests linked in my post above?

I calibrated direct from the bluray and standart player with a calibration dvd - never connected via computer.
I use oppo and panasonic players per hdmi because a good source is essential for a good image.

Interesting you should mention this..
I've had a greenish tinge in some lighter scenes that is there sometimes and not others..and some occasional yellowish tinges on skin tones..
I tried all sorts of general setting changes and RGB changes and was only ever able to reduce these tinges slightly..

To cut a long story short, I finished up (after calibrating with Spears and Munsells blu-ray disc) with these settings..

Contrast ..2
Brightness..1
Temp..Cold
Mode..Bright
Degamma...Graphics.
BC..2
TV..2

RG..-12
GG.- 12
BG. -5

The end results was fairly good, nice bright image but not perfect..Still some tinges were showing..
I decided to try your gain settings, leaving everything else unchanged..
The green and yellow tinges were gone, but now there was a pinkish tinge creeping in..
I reset the gain to these settings..
RG.-16
GG.-14
BG. 0

That produced the best image I've ever had!
Very natural skin tones with no tinges of any other colours, and still a nice bright image with good blacks and whites..
I'll run the S&P disc tonight and see how the gradient grey scale looks now..

Thanks for your input..
