Contrast ratio is kind of sucky, unless Panasonic is changing their method of reporting it. Most manufacturers use a false "full on/full off" method of opening the iris completely and running the lamp a maximum brightness to get the brightest white image, and then they turn the projector off (as in powered off) to get the lowest setting, and come up with a contrast ratio. This isn't something that only Panasonic does, so I am not picking on them.
When they rate their other popular projectors at 500,000:1 and this one at only 20,000:1 I am concerned. Then again, if it is a REAL ratio, then that would be better than their 500,000:1 projectors (that really show about 10,000:1 in real world examples).
Either way, pretty darn cool if they get that tech going. It will make projectors potentially brighter and run a lot cooler (less fan noise).
