The Optoma HD71 projector is a high brightness HT-720p projector at a fairly low price. Specs say 2400 lumens I was able to register 2000 lumens for a 106" diag screen in it's brightest mode. You can tone it done to 800lumens by using the Cinema mode vs the bright mode menu choice. The projector uses a new color wheel that is (RGBCYM) at 4x speed with the new brilliant color 2 to reach this nigh level of brightness. What's very good is black level with this high brightness.

I got out HD-DVE and went to tune the BASICs but in each case no adjustment was needed. Looking of the graysteps pattern it showed the grayscale as looking very good and natural gray. I'll get around to trying to tune it with colorfacts later. Thought I should get the review started with some pictures.

Cool Features are,
It's has speaker sound that has volume and mute. HDMI will pick up the sound from your HDMI DVD Player, or HDMI SatTV/Cable TV.
A sliding Lens Cap.
Superwide feature for a 2.01 setup to eliminate the bars on 2.35 video.
The case is always good to have.
DVI and HDMI inputs.
Super quiet fan.

The bad, there's light spill out of the case that will reflect on the ceiling. Avoid looking at the ceiling.

Enjoy, travel case & projector

Thanks Tom for posting this review. I've been waiting for this as I'm trying to decide between the HD65 (which you also seems to think highly of) and the HD71. I have the HD65 now in a light controlled room. Just hope you might share your thoughts on how the two compare:

- Noise level - my guess is the HD71 is lower?
- Contrast / black level - would I have to worry about the HD71 being too bright? how do the two compare.
- I believe they are both the same throw distance?
- do you know if the HD71 VGA input will take a component video signal (HD65 does).
- The HD65 seems to be quite sensitive to "losing signal" (e.g. DVD cut from menu selection to start of movie; Wii goes from one game scense to another). It doesn't happen all the time but just annoying.


Thanks!!

They're really very close and I wouldn't trade up from a HD65 to the HD71. The HD71 is for new buyers to consider it's extra features and different style. They're both producing eye popping images, very very similar to each other.

I have a 106" diag dalite high power screen. The PJ is ceiling mounted so the gain is down thank goodness. You know when a bright scene hits the screen the whole room lights up. Brightest projector for me so far. I got 2,000 lumens out of it in the minimum zoom so we could add another 20% or more if the PJ is mounted closer and the zoom opened up. Imagine even brighter.
I think it's a good idea to start out with super high brightness because as we know the bulbs do taper down pretty fast. This way you should have a bright picture most of the bulb life.

It's quieter, comes with a travel bag, has sound, being brighter means images will stay brighter as the lamp ages. Things to consider

Tom,
Why dont you post contrast ratios, color space charts, and color temperature charts before and after calibration. I have seen you post these before.

Haven't got around to using colorfacts yet. Though mostly I find the machines with brilliant color bring out a red bias when you use the color meters. Then I prefer the OTB settings over the down tuning. I will check it though.

Guitarman, how the image quality of HD71 compare to HD73? I have a HD73 and I wan't to buy the HD71 so badly because of low light output from HD73. I litterly have to close my door, window, and turn off all light just to watch a vagely image from HD73. At night is when I can see the true pontentail of the HD73, but during the day, it straingling my eye. I don't know if the HD71 2400 lum would be sufficient enought for day time gameing and video with out trapping myself in darkness? Please let me know. Thank! I had a HD70 to, and the different between HD70 upgrade to HD73 is amost like just receive new eye glass. More detail start to review itself to me and all I have to do is just look and start noticing it.

This will blow your mind. The HD73 is a DC3 projector but I personally would buy the HD71 in a heart beat over the HD73. I've become a lumens junkie anything lower than 1700 or 2400 just leaves me bored with lack a brightness. As long as they can keep blacks looking good and they do, I'd pick one of these light cannons. Right now there are three with this new wheel RGBCYM, the Optoma HD81LV, HD71, HD65.

"night is when I can see the true potentail of the HD73"

But you're right in a bat cave the HD73 will show it's potential. I still prefer at night with TV shows like Lost, Prison break, American Idol a projector like the HD71. The shows at this level of bright are more fun to watch.

This is very tempting. I've got a Mits HD1000 with a noisy, and I mean NOISY color wheel, and this would solve my brightness issues as my bulbs have aged and give me a bigger picture as a bonus.

It's only $1,500 CDN too!

White wall or screen is a great match for these PJ's. Screens are better for the black surround border. Mat white will be just fine, plus it doesn't show waves when video is on it so you can use a low priced non-tensioned model. Plust mat white is a low priced texture. You can get Dalite's for just over a bill.

guitarman, I will have to shelf mount this PJ behind me near roof hight. Will there be issues with lying it on it's top/upside down?

I have to do that with my Mits HD1000 and it's a pita. The unit is curved on top, and has the power buttons protruding. When I shift it around to get it to fit my painted wall screen the thing powers off, won't stay where I put it, etc.

Thanks in advance.

Looks like you won't be hitting the power button it's out of the way, there's a center button that's much higher but it has no use it's just there, that would protect the power on button which is nearby and flat out of the way. But the focus and zoom rings will be hard to get at.

Many times new purchasers have had colored walls and were surprised how good a PJ image still looked. A Mat White screen is a better way to go, your projector receives it's just place for the great video it's doing for you. The black border makes a world of difference for a theater look.

Either of these methods should work. I mounted 3 pjs this way in 5 years without any problem.
1. Get some tiny rubber feet from Home Depot to stick to the top of the pj, then rest it upside down.
2. Nail together a square frame with 1x2s, slight smaller then the top of the pj, then rest the pj upside down on the frame.

Get a mat white dalite screen, they're very well built and will work perfect with the projector. To save money you can get a Model B pull down for cheap.

Hey Guitarman,

I'm seriously considering purchasing a HD71 soon after months of hesitation. My only concern now is with the sound. Does it come with something that has good sound or would I need to look into buying some speakers as well? Hope you're still around here! lol thanks in advance

Dude...
Projectors don't come with sound support. Video only, unless its an OLD business projector that has a one inch speaker to play the beeps and boops of your laptop powerpoint presentation.

Hi guitarman,

Have you ever seen or owned a Mits HC3000/HC3100?

Can the HD65 or HD71 compare to the Mits HC3000?
