I’ll figure out the other picture, but may I assume you are talking about Ernest Borgnine (McHales Navy, etc.) (our image, from the movie Red). Lorne has been dead for some time, I believe (Bonanza). -a

The big differences are black level performance (the HD33′s pretty good, for the price, the GT750 – definitely not a match. And of course, the HD33 is going to be sharper, being a 1080p projector, not a 720p projector.

So, the real question is how much better, and what are you doing with your projector, the room, etc. For example, most non-enthusiasts – seeing two fairly similar projectors, one with just a slightly better picture, but not quite as bright, and the other – the opposite. Most folks will simply prefer the slightly brighter projector. But, if you are into movies, etc. you will really appreciate the black level differences. Now, budget allowing, if you are considering the HD33, definitely also consider the Epson 3010, which I’m working with. It’s got the HD33 beat in many ways, for the same money. (The HD33 has its strengths too, but I’m more impressed with the Epson as you will see from the write-up… -a

The two images should be bright enough to lift the darkest shadow detail and make it visible. In some photos of the train, the info just isn’t there, despite the overexposure. Especially on the shrubs on the right – behind the track.

The image can also be used to compare black level performance. Assuming two projectors have the same brightness to the letterboxing, then the one where the scene is the most overexposed, is the one with the better black level performance. OK? -art

and after taking a third look at the train shadow detail pictures, the hd33′s looks so much less natural and overly bright compared to the gt750…. i hope you take a third look at those pictures as well and can tell me how much i should value this particular picture comparison.

i just asked the following in hometheaterforum.com, but i would have posted the question in the comment section to your reviews first, if i had found one.

“thanks very much for the review(s), but i am really missing your subjective comparison of the hd750 and the hd33. i currently could have the hd33 for just a little bit more than the hd750, but many years ago i had a bad experience with a projector with very bad detail in the darker areas, and… generally no black level to speak of.

in Art Feierman’s review pictures (after calibration) of the hd33 seem to have a lot less detail than that of the hd750 (train in the woods example), but i just found the uncalibrated pictures of the hd33 as well, and there i see that much more detail than in the calibrated pictures is possible, probably at the cost of black levels.
also, for the review they never calibrated the hd750.

so… how fare the two compared to each other after your reviews?

thanks very much in advance for a quick reply, if possible, since i dont know if that low price for the hd33 stays for long in my currency.”

Couple of things I noticed :
- picture of Lorne Green links to a picture of a lion in the snow
- Under lamp life, eco mode is stated as 4000hrs, while in the overview more at the top it says 5000hrs
