And the DLP vs LCD question I am also curious about as I want to upgrade to the HD65 but am also looking at the Epson 720.. so if DLP is what I want to stick with the HD65 is the one I will get..

The 8 hours comes from the factory techs. The two hours is actually conservative. The wait time comes from the bulb filiment, it's in a vunrulable point as it's dorment after shut off. So the best you can do to stabilize the filiment after shut down by not bumping the pj and not re firing up before it's fully stable will make the bulb last much longer.

So here's my money question: Does it hurt to watch? Neither of us is particularly rainbow-afflicted, but have you gotten that H31/SP4805 type fatigue watching the HD65?

Nope no eyestrain at all because of the high brightness, no rainbows either form me.

I am in the market to upgrade my Optoma 739. I had originally thought of either the Panasonic AX200 720p projector or the Mistubishi 4900 1080P unit. I am now thinking of the Optoma HD65 unit for several reasons; cheaper than both the others, have had good luck with my 739 and also I believe my 739 mount will still work on the HD65. Any input on these? I plan on using it mostly for movies using an Oppo 981 dvd player, some game play with the kids Wii and may add a blu ray player soon. I have it some light where the projector is located. but could have full light control if needed.

Umm .. there is no filament. These machines have short-arc lamps (invented by Philips). The bulbs are still VERY vulnerable when hot, tho. That's why the very short cooldown (with the lamp still lit!) on shutdown concerns me.

Right so they know what I mean. Be cool when first aligning the projector, easy movements.

Yesterday evening I set up my HD65, and here are the results.

Source: PS3
Software: DVE PAL + ColorFacts Professional™ 7.0 (with Eye-One Pro Spectrophotometer)
Cabling: 10 meter (3.3') HDMI (Jenving)
Signal: 576p upscaled to 1080p
Screen: 2 meter (6.6’/78.7”) wide Xus matt/white 1.0 gain
IRE100 (window): 16 fL (~387 calibrated lumens I guess)

Minor adjustments for the grayscale, but Brilliant Colour and TrueVivid at 0, otherwise my intensities went through the roof.

Worked with Display Mode Cinema and Degamma PC, which felt the best eye-wise.

What I like the best with this unit; it´s really bright, still fairly accurate colorwise, quiet and disappearingly small. Also no issues with 1080p/24!.

An idea of how the projector displays a SD content, then some pictures of Wii playing Excite Truck via Video Composite.

Just wondering if anyone can let me know a little about the vertical shift of the projector. My basement height is about 8 feet high and I would like to have about a 120 inch screen if possible and the bottom of the screen about 2.5 feet off the ground. Is it possible to have this kind of setup with this projector?? If not what is the largest screen that I could have with the sealing height??

Plus the vertical shift will raise or lower the image by 3.5" on my 106" diag screen.

Me too, but I am thinking of the HD71 instead. If you upgrade, I'd be very interested in the comparison with the 739. I too, have had great service from my 739 - made me a big fan of Optoma.

Yep some machines in all groups can give problems, thx for the warranties. But overall many a very many are just fine. Personally I haven't had hardly any that gave me a hard time. I have to say these new very low priced 720p machines with the RGBCYM colorwheels are the tops in in your face video. I think there's going to be a huge amount of happy customers with these machines. Count me in the the group, I plan on buying / owning the HD71, it's a killer machine for scraps of dough.

Okay, I am starting to love this projector. I am watching Back 2 the Future right now. SD_DVD with Toshiba a3 over component (480p). If I didn't know any better, you could tell me it was HD DVD and not only I would be impressed I wouldn't doubt the claim. The distant backgrounds are a bit soft, but for the most part...

HUBBA HUBBA!!!

Who needs HD when this looks so good!

And BTW
Tom,
Thanks for all of your support and help. It's people like you that keep this hobby fun for the average joe that really needs the help.

I need help.

Today I bought the cable Video Component for the Wii and the Wii set to 480p.

In all games presented the problem of the "hand shake".

Someone could help me? Please.

Even with the source lock on, the problem persists.

In Wii Sports, when I would Strike, the screen goes blue and after a few seconds it returns to normal.

If I set the Wii for 480i, the problem does not appear, but the sharpness is damaged. The signal of 480p Wii is better. More clear.

From 15' the HD65 will throw a 128" (+or-5") image. I don't think this projector will work for you.

Check the throw calculator here:

It has been found that extending the cool down until the lamp is room temp is actually cooling the lamp too quickly from the high temp and pressure state it is in while running and leads to micro-fractures in the lamp and a premature failure. A short cool down period will move enough heat out to protect the PJ but allow the lamp to cool naturally. Infocus found this to be happening on their PJs and started advising owners to just cut the power when they were done watching rather than run the cool down fan for several minutes. Scan the X1 and SP4805 threads and you will find owners who do just that and have had no problems.

The zoom on the HD65 is somewhat limited. At 15 feet you get a range of 122" to 134". The zoom on the Epson Powerlite Home Cinema 720 is much larger in comparison. At 15 feet the zoom gives you a range of 144" all the way down to... 68".

great info - thanks
Since you know about these lamps can you tell us how much time should go by for a restart? It was mentioned 8 hours here but I assume that is too long.

Your user manual should have this but usually it is 20 to 30 minutes.

Can somebody say which is better HDMI or Component for this projector when connecting it to a PC with good graphics card.

I plan to buy one of the 20 footers from monoprice. I cannot decide?
HDMI is costlier than component. But is the price difference worth it?
Please help.

Component does look great but HDMI/DVI has always been better.

I have wanted to get a projector for a number of years, but with everything always changing and advancing I never felt comfortable spending a couple of grand on one. Then I decided to just lower my budget to under a thousand just to get my feet wet and then not feel so bad if I trade up in a year or two. Reading this thread made me decide to take the plunge with the HD65. I had a 12% off one item coupon for BB and picked one up on Monday. Tuesday was my b-day and I ended the evening with setting up the projector. I love it and that's with it connected to my old pioneer 480I DVD player and projecting the image on white wall. The wife was also quite surprised by how bright the image is. I'm sitting here right now watching "Poseidon." My sincere thanks to all. I am looking for any suggestions where to order an extra bulb?

Decided to hook up the HD player. Wow! Just got done watching King Kong and it looked pretty darn good. I'm very pleased.

should have gotten bestbuys 4year extended warranty for a couple hundred bucks extra. it includes free bulb replacement and then also covers your projector. i, just last week, took my hd70 in for service cause it was messed up. i ended up getting to upgrade to the hd65 and didn't cost me a cent. unless replacement bulbs have come down in price, the extended warranty will likely cost less than your first replacement bulb. just my .02, enjoy your new pj!

They'll probably send me a warranty offer in the mail. It's certainly something to consider. Thanks for the info!

Yes it is compatible for constant height setups. Letterbox raises the image and the lens expands it out to fill a CH screen. About all the Optoma projectors do this, except for the dinosaurs.
