I upgraded to this projector from my HD20 and had a chance to compare them on my 150" 1.1 gain screen.

Out of the box the black levels looked slightly better than the HD20 but not enough to call it an improvement IMO. However, the contrast difference to me is a huge improvement. The picture looks much brighter and the higher end of the grey-scale has much more punch to it. I first A/B'd How To Train Your Dragon in 2D and it was immediately obvious that the HD33 outperformed it on contrast and overall color saturation. Much more WOW and POP to the picture.

The HD33 was a little quieter than the HD20 in both modes as well. Standing six feet from them while they were at idle, I could clearly tell which one was making more noise... that being the HD20, with the HD33 only emitting a faint whir from its fan. In 3D mode the HD33's fan kicks up a little but nothing too bad... the HD33 sounded just as loud in 3D mode as the HD20 in eco-mode for comparison.

I am not very sensitive to the rainbow-effect but I know several movies which I could go to several scenes or the end-credits and make it occur to my eyes. With the HD33, I could not produce the RBE through those examples as I had done with the HD20. On the HD20, I normally could see RBE sometimes on the end-credits to Avatar (white-text flowing over animation and then a black screen) but with the HD33, they were gone, no matter what I tried.

The projector has zero crosstalk or ghosting which was tested on several of my 3D Blu-rays. The 3D performance on this machine is phenomenal and to me well worth the money spent. One of my tests, How To Train Your Dragon in 3D, looked great. I only have one set of glasses but my friends (who are non-videophiles) tried it out and were both impressed with it.

Verified Purchase
Okay let me start off saying that like most I was sitting on the fence between 4 differant projectors for the last month. I thought and pondered and then thought some more, I frequented Projector central and amazon obsessively during this time.

I have a light controled environment from my previous projector so Based on the info about the epson 3010 and reviews saying it is just too bright in a cave and others costing more then double these two models prices I wound Up taking a gamble and decided I will try my first DLP unit. I ordered two pairs of the OPTOMA RF GLASSES and set this bad boy up.

Upon getting everything setup and without having fine tuned anything I turned it on and immediately began testing the unit with various 2d and 3d material via blu ray disc...I must say I cannot believe what I have witnessed and at this price point.. I was skeptical.. Not anymore...

I started off with despicable me 3d...Umm amazing...Then tron 3d.. Some scenes will possess you when the 3d is in full effect..Which is funny because I was hardly impressed with tron on my plasma...Then open season, and once again I am impressed..I cannot wait until my free copy of AVATAR gets here......

Now I Grab some good old anime..Yeah dont judge...I am an anime Nerd... Akira and neon genesis blurays totally got me back in the anime watching mode and looked fabulous..

Then I decided to make sure my WIFI was connected from the basement and tested out netflix.. The HD content usually looks close to a bluray or HDTV broadcast on my 50" plasma and although it was still pretty good it was more along the lines of 720p or 1080i at best. There just wasnt as much pop..

Just received my HD33 Saturday Sept. 3rd. I was not sure how good the 3D would look, now I cant believe how good this projector is. 2D images are very good, it reminds me the Sony I have and will continue to use it for regular movies, VPL-AW10, got this one back in 2007 it has 1024 hrs on the lamp, and it is still looking Very Good, I should change the lamp when reaches maybe 2000 hrs.
Back to the HD33, this is my second 3D pj, got last dec.2010 the LG BX327, but never liked, bad image contrast ratio, poor 2d, poor 3d and 4:3 native, just bad. I think it will be going to the trash tomorrow.
The HD33 is amazing! The 3D quality is impressive. I tested it in several movies I have and they came out excellent.
The unit is solid, and much better than from the pictures I've seen.
I was thinking to get the Sony 3D projector or the Panasonic model, but I am glad that I chose this one.
It will work just fine with the DLP Link glasses, I prefer this one over the RF glasses. I've tried those in the past, just couldn't bear the flickering, you wont see flickering on the DLP link ones.
When watching movies remember to turn the PureMotion off, it will give a more natural look to the movie. The PureMotion was meant for sports, races, otherwise your movie will look "speedy", the " soap opera effect ."
About brightness, in 3D mode images are perfect, did not think it was dim at all. You are able to control the brightness level as you like it, without living the movie!
Well, I am very happy with Optoma HD33, and would recommend to anyone considering a 3D Home Theater Projector.
I will be getting an Extended Service Warranty, 3 or 4 years would be reasonable, just in case.
