it does have limited placement options. the pj lens has to centred for the horizontal plane to keep the image square.

the digital keystone correction allows some height adjustment at the expense of losing 1:1 pixel mapping for 1080p.

my diy mount has some minor adjustable parts to help me acheive the optimal placement.

Hi Custard,

I have tried both calibration methods and really prefer the 75% for its pop and life like quality. Keep us posted!

i did end up testing the 75% levels but found i could not improve on my settings.

i probably should have spent longer with it - i hope to have another bash at 75% once i reach 500hrs.

If they offer a rebate like they did on the HD70 when I bought it, I'm going to have to upgrade.

4000:1 CR sure ought to blow my 1000:1 out of the water.

Well firstly you're looking at two totally different projectors..

The HD20 is a DLP..and the HC720 is an LCD..
That's your first consideration, as to what type of system you prefer..

I've heard very good reports about both units, particularly for entry level projectors..
The HC720 is the brighter of the two, so if you have any ambient light considerations, or planning on using a grey screen, then that's something to take into account..

Optoma's certainly don't have a good reputation for lamp life..

The difference between 1080p and 720p. is debatable..
Some say that you can see the difference quite clearly, others say that they can't see any difference..particularly at this level of projector..with both types having low contrast ratio's..

If you're not able to see both units in operation (and then they would have to be viewed in the same environment) all you can do is go on other peoples experience with each type..

Well for better lamp life.First of all do not allow your projector to become overheated. The most frequently cause of lamp failure is excessive heat. Please follow the instructions in your user manual for powering down the projector and make sure that the projector has an adequate cool-down period. Operate your projector in a clean, relatively dust-free environment.Please make sure that you clean the air filters regularly. Utilize the "economy mode" if it is available with your projector model. Last Longer

Looks great 1080 is beautiful but i cant wait for 2560 x 1600 like the high end computer LCD's thats going to be the day nice set-up i like i think projectors are especially great for underground theaters where the light is not a factor that contributes to the pain received in watching movie.
