The Casio projectors are terrible for color quality and aren't just noisy, they are outright loud.
I've tested about 5 different Casio laser hybrid engines and they are a very unique breed of projector which Casio has absolutely fallen flat on its face to deliver the best possible product to consumers.
It is still an extremely budget friendly projector concept, but it absolutely has terrible colors on all their mid-sized models or smaller.
They have their A series, M series, and H series - small, medium, and standard size.
In a shootout between a properly color balanced projector, the Casios were way off on color in all modes, and this is a well documented fact from people who have tried to use them for home theater. Likewise, the high pitched whine from the tiny fans is extremely intrusive to any home theater viewing experience.
What's most unfortunate, is that their H series projector doesn't have this issue.
Why is that unfortunate?
Because every OTHER model they produce they have a 1280x800 native widescreen, but the H series is limited to a XGA (1024x768) projector only. The larger case of that model allows for the extra filters needed to produce a projector which has colors that are far more accurate across the board. As well, it gives room for a full sized fan which moves more air, with less noise.
The entire reason lamp based home theater projectors are so large is not because they have to be, but because the larger size allows for more airflow and less noise! Something Pico and micro projectors just don't deliver, yet no manufacturer has figured out that if you build a full size LED/laser projector with 500+ lumens, in at least 720p format, or better yet, 1080p, and get the colors close to accurate with low noise, that the home theater market is really dying to make it their go to product.
As much as I wish I could recommend the Casio projectors for home use, I simply can't, and I was very excited when I saw their projectors for the first time.
Hopefully Casio will release an H series projector with native HD resolution in the next year so I can test that out and start recommending it to those on a budget.
The hard part is that for about $1,000 you can pick up a true 1080p home theater projector with a lamp which will last about a year or two for typical home use. For those using it 'occassionally' then it could last 3-5 years on the first lamp, which means paying a few hundred dollar premium may not make sense for many at this time.
Still, I would like to see what Optoma will deliver with a follow up to their 500 lumen micro projector.
