No home theater projector will do good in those cases. You are talking about a severe drop in contrast ratio as soon as you allow ambient light to enter the room.

Could you image how 'fun' it would be to go to the movie theater and have them leave the lights on during the whole show? Front projection requires a room as dark as possible. If you want to view during the day, then invest in VERY good blackout curtains (commercial grade) which will make your room pitch black during the daytime.

Then, almost any projector listed above will suit you fine. I would likely go with the Optoma H79 or, if I wanted something nice, the Sim2 HT300. The projectors you are looking at offer superior resolution, but no real added brightness. They aren't SUPER bright, they are just 'bright'.

Super bright is the Sanyo HD-10. That is one crazy bright 1080p projector. With the WF-10 being a solid contender as well.

Would I recommend them? No, they are overkill for home theater in most cases.

Now, I'm not saying that the Sony isn't a killer unit. I've seen it, I think it looks great. But, it is not what I would call practical for all but a very few circumstances. The H79 and the HT300 both are great performers and I would consider them best-in-class at their price points.

I have no idea what sort of treatments or additional stuff is going on with your setup, but I know that the stuff I have worked on in my area has all been either dedicated home theaters with no windows, or rooms with true blackout curtains (motorized) that handled 100% light control for solid daytime viewing. The one (1) time that we did not have good blackout curtains the customer complained incessantly that the projector was no good.

Contrast, in a lit room, often drops to levels closer to 20 to 1. So instead of a 3,000:1 or higher ratio, you lose all the impact you had.

Hello again. Final question (hopefully): I know that the further away I put the throwback distance for any projector, the less the quality of the picture, but my question is that can I play around with the zoom? In other words, can I put the projector closer to the wall (20 ft instead of 25.3 ft) and increase the zoom to 1.27 instead of 1.00 and still get excellent quality picture while still keeping the 160 inch screen? Thanks.

Luong - It depends on the projector and the lens. But, with the exact projector you just listed, the answer is 'yes'. I would 100% get the Qualia over what you just listed though. 3LCD chips are really not for home theater use in about any way that I can think of at that price. The Qualia LCoS chipset blows it out of the water in many ways. 720p DLP also blows it away in my opinion.

BUT:

Why would you think that the further back you place your projector the worse the image is? Where did you hear this information?

The larger your SCREEN is, the worse the image appears or the closer you sit the worse the iamge appears. The bigger factor is the worse the source material, the worse the image actually is. If you had perfect optics, you could project from 1,000 feet and the image would look great. That is (obviously) an exageration, but with a good lens on a good projector, any distance they give you to project from is perfectly acceptable.

20 feet, 15 feet, or 30 feet... It won't make a huge difference in image quality. In my opinion, the further the projector is from the screen, the smoother the image will appear due to a smaller angle of incidence between the projector and the screen to all seating locations.

My contractor's friend who happens to own an entertainment store told me this. He said that the further back the projector is, the much you lose brightness and contrast, and hence, quality. He recommends no more than 23 ft back for my projector.


"...If you had perfect optics, you could project from 1,000 feet and the image would look great. That is (obviously) an exageration, but with a good lens on a good projector, any distance they give you to project from is perfectly acceptable."

Will you think my Fujitsu will work fine at that distance? I had to do a lot of investigation to get this throwback figure but I would like to get your opinions.

Thanks.

Yes, the projector will work absolutely fine at that distance. I have found that most A/V sales guys (especially sales guys) are clueless on the engineering side of A/V.

Good luck with the Fujitsu.
