True Contrast. Help Please. - Blu-ray Forum

Leapold BUTTERS · 05-28-2007, 08:46 PM

Okay, I am buying a new TV, and it will either be a 40" samgsung or a 42" sharp, they are both pretty much the same, except for 2 things. The samsung has a True contrast ratio of 10000:1 where the sharp has a True contrast ratio of 1000:1, which is better? and what does it mean? also, the sammy has a response time of 8ms whereas the sharp is 4ms.

10k:1 is far superior to 1k:1 in preserving black levels. 1k:1 was the standard for digitals five years ago. I'm almost surprised they're still even making them. 10k:1 is about the best you can hope for in the current market of digitals. But, they're pushing it higher every year.

Contrast

"Contrast is the difference in visual properties that makes an object (or its representation in an image) distinguishable from other objects and the background. In visual perception of the real world, contrast is determined by the difference in the color and brightness of the object and other objects within the same field of view."

Basically it is the total range from one end of the color spectrum (white) to the opposite end (black)...the greater the difference, the better the detail...

so to answer your question...

10,000:1 is much better than 1,000:1

although the new sammy`s lcd`s have 15000:1 which is even nicer lol and more hdmi inputs shop around a bit

10k is better than 1k IF it truly is 10k and 1k we're talking about. I seriously doubt that the two displays had CR measurements taken using the same method, equipment and test environment. While CR numbers were iffy a couple of years ago it's just gotten worse, and these days it's become a casualty of the marketing wars. Same for response times - you can't really trust the response time numbers as they'll do stuff like only list grayscale times, or only "on" not "off" etc.

The specs you should go by is size, resolution, type and number of connections (unless you have an AV switch), technology type (LCD, DLP, plasma etc), and sub-technology (what type of LCD panel, DLP chip etc). Once you know which displays have the features you want in that regard take a look at them in action, preferably in a calibrated environment with material you're familiar with.

Yeah, i have seen some at 15000:1, but they are out of my price. this one is a 40" 1080p, with 3 hdmi inputs. I looked at it a few times and from what i have seen it is one of the nicest. I will probably end up with the sammy.

What's your budget and how often do you see films (BD/DVD)?

I would go with a plasma if your watching alot of movies, and 1080p is not the most important feature. Better to make sure it accepts 24p input.

Good luck!

I watch my BDs/HD DVDs a lot, and my budget is 2500. http://www.futureshop.ca/catalog/pro...0079999&catid= that is the sharp i am looking at, and the samsung is this one http://www.futureshop.ca/catalog/pro...0086238&catid= both 1080p. I dunno how to tell if it supports 24p input.

Blackraven · 05-29-2007, 11:20 AM

If you want truer or more real-world contrast ratios, there are two ways on how this can be seen/measured:

-ANSI contrast
-full-on/full-off test

Hope that helps

www.onecall.com is selling the samsung you quoted for $1750. If you can spend $2500 then you should go for the 46" model.

BTW, I'm very happy with my 37D62U. Contrast is very good after I calibrated the set.

Leapold BUTTERS · 05-29-2007, 03:01 PM

^^ yeah, the samsung i am looking at is the same as my little 26" only its 1080p and 14" bigger. and i played with my settings until it looked amazing. but the sharp looks so damn good too. lol. at the store i am looking at they have a blu ray player hooked up to both, so i am just gonna ask them to put the same movie in both so i can look at the PQ and choose which one is best.

If you are gonna test the Sharp, make sure you watch it with an AV-mode (e.g. Standard, Dynamic) that has the "Enhanced Picture Contrast On". This gives you a dynamic contrast of around 8500 if I remember correctly. Not all AV-mode has this feature. I mistakenly set my Sharp to "movie" mode when I calibrate initially, I never get the PQ I wanted until I RTFM.

slee915 · 05-30-2007, 12:58 AM

Looking at the spec of the Samsung you quoted, the 10k:1 contrast ratio is only the dynamic contrast ratio, not the true contrast.

http://www.samsung.com/Products/TV/L...4061_final.pdf

The future shop spec is wrong.

darkpoet25 · 05-30-2007, 01:53 AM

If your budget is $2500 you should look into a Sony 50" SXRD 1080p LcOS tv. You can find one at Best Buy for less than that. My brother and I have one and the picture is amazingly clear. I personally wouldn't go with a plasma. Mainly due to the fact that they are filled with gas making them heavier and they don't last as long. I work for Wal-Mart and we get quite a few plasmas returned. LCD, DLP, and LcOS last longer, don't have as much of a chance as for screen burn in, and can have far superior picture quality.
