wich is the contrast ratio of this item?

It's completely adjustable. Best solution is to use one of the Blu-Ray calibration disks (Disney has one which is relatively low cost and is the easiest to use - Disney WOW) and to tune the projector to the individual screening environment (ie a dark room versus one with windows and curtains) which will have a much greater impact on contrast than the projector itself. The projector also allows for several different settings that can be saved ranging from Games to High chroma digital viewing to Digital Cinema.

I don't disagree that it is intended for close objects. That being said, the image at distance is remarkably clear.

It's important to note that there are two elements to the contrast ratio. There's the contrast provided by the 3 LCD screens, and then there is they "dynamic contrast" added by the auto iris that adjusts overall picture brightness. The 5030 is an advanced iris that boosts apparent contrast -- and I have to say it works pretty darn well. Even dark scenes have solid blacks and contrast. That said, it's almost impossible to set up a direct comparison (same lighting conditions, same materials). I'm very pleased with the 5030UB, but it's whatever you like/want to pay.

The 42RV530U dosn't have many reviews, Should I get this set or the 42RV530U? The 42RV530U supposedly has a contrast ratio of 15000:1, but its missing the colorburst tech and its cheaper on the Toshiba website.

The ratio of the luminance of the brightest color (white) to that of the darkest color (black). In simple words the more contrast you make in a projector the colours will become faded & vice versa. 300000 is the contrast of this projector which gives phenomenal blacks.

Color gamut and contrast ratio are actually about the same level of importance. You want both to be very good. They're also somewhat interrelated.Also, static contrast ratio is more important than dynamic contrast ratio (it's pretty easy to increase dynamic contrast ratio without improving actual picture quality one iota - just completely turn the backlight off when the screen goes black), and the difference between the 61 and the 65 isn't very significant in that regard.

The further back you put it, the larger the image. However, I have found: a "good" image around 48-52 inch diagonal on a real roll up screen in a very dark room. Anything else I said would be theory.

sorry have not had mine long enough to answer that. but i will tell you that the magnification is not what i expected.would have sent it back but my husband 'hard wired' it and i did not have the heart to tell him i was not happy with it. don't buy it!

According to Panasonic's website http://www.panasonic.com/business/projectors/pt-ae7000u.asp it says 300,000:1 contrast ratio and 2,000 lumens of brightness. It looks brilliant to me!

If you fins something please let me know. The contrast of the screen is terrible!!!

BB is correct. Think of it in the same manner as the way they sell a digital camera- optical zoom vs digital zoom. The difference between contrast ratio and dynamic ratio can be equally as confusing to the consumer, but still, the higher, the better. Just make sure you're comparing apples to apples.

The photos stacked to show color of lighting are wrong the others are correct! ? is also / Key and the \ is above the enter key. I hope this helps....Barry

I don't remember the resolution but they show very clear...only down side is, they aren't that bright.

Don't know, but the numbers are about an inch and a half tall - and there is very good contrast between the numbers and the background. It's much larger than other displays I've seen.

The reason is small... There is a 20000:1 Contrast Ratio but a 60000:1 Dynamic Contrast Ratio, aye, there's the rub as they must have something to do with settings as you'll notice when you pick a picture mode on a Samsung: There is a Dynamic setting as opposed to Cinema or Standard. That must allow for those differences. Thank you for making me realize the answer to my own question to someone else recently!!!

I believe the main difference is the dynamic contrast ratio 8,000,000:1 vs. 12,000,000:1

Toshiba doesn't reveal it. I believe the reason is because there is no universal standard inwhich to properly measure/ascertain the contrast ratio. However REGZA is Toshiba's top of the line LCD TV series, so estimates put it very high around 8500:1. I've seen this TV in person, looks gorgeous and the reviews are solid.
