This test does point out several things that are very important. Front projection is most demanding/least forgiving; it has many variables, each which makes maybe a small effect on its own, but can have a very large cumulative effect with other variables. The lesson learned is to keep each variable at the highest quality possible.
The interesting fact that is implied in the event, and one poster brought up, is how our visual perception and acuity relative to screen size/viewing distance and resolution is so important. http://www.carltonbale.com/blog/2006...p-does-matter/
Finally, what do you think the chances are that you will find many run of the mill installers/retailers who will look at your design, examine the visual acuity/screen size/distance factors verses resolution, find that you will not be able to detect the difference between 720 and 1080...and tell you about it?
Nah, most are going to sell you the 1080p for the $.
Nevermind about them properly considering all the other variables for you.
As I said in the beginning we tried to make this shoot-out as objective as possible.
It was not in any way a controlled scientific experiment
but more an honest attempt to see in real life the differences between the 720 and 1080 DLP panels.
In that respect we took all precautions we could think in order to make this test valid:
1) We used one screen in a tottaly light controlled environment
2) We had the projectors D65 calibrated and matched in brightness by an ISF certified professional.
3) We locked both projectors to their native resolution by 1:1 pixel mapping, avoiding thus the use of both projectors internal scaler/deinterlacer.
4)We used two HTPCs with the identical hardware and software configuration
5) We hand-picked the best out of dozens of High Quality HD 1080 clips available (I have around 800 gigabytes of HD material in my Hard discs) to ensure that, if there were any differences, the material would reveal them! Let me tell you, that the clips used are FAR better than the HD demo clips than the ones used to demonstrate the Sony, Samsung and Panasonic BluRay players.
So, I sincerely doubt that we would have different results if we had used pg. two BRays or HD DVDs.
