What's the Real Deal with HDTV Contrast Ratio?...

Relating to this thread: http://forums.cnet.com/5208-7596_102-0.html?forumID=60&threadID=230937&messageID=2388497

I'd really like to understand the deal with Native contrast ratio vs. Dynamic contrast ratio...

I've noticed better pictures with higher contrast ratios, but I'm not certain of how each company typically calculates or designs for contrast ratio. And is Dynamic contrast ratio like some applification of natural contrast ratio, thus being very suseptable to "noise" like some digital zooms on digital cameras?

I'm trying to decide if I'd like to get a Samsung 32" or 40" LCD with at least 4000:1 contrast ratio or a Sharp 37" with 1200:1 native contrast ratio but a whopping 6000:1 Dynamic contrast ratio... The picture quality looks quite good on all these displays, but I do wonder if this "new" Dynamic contrast ratio technology has much longevity if done by one company or another...

Why am I picky about this, well I'm am ametuer photographer so that's basically why I'm a bit picky about picture quality - otherwise I would've just picked a Vizio and been done with it...

Best,
Shalin

Shalin,

i hope i learn it by the end of the year, i'm planning on buy a 19 inches lcd monitor...
it's 800 hundred bucks in Brazil, and getting cheaper!

plasma tvs are still a little expensive here, but affordable... the only thing i know is that in 2010 i'll be watching the world cup in a plasma tv at home!

thanks Shalin!
i have bookmarked it, for when i buy a lcd monitor later this year (contrast ratio will be one topic i'll evaluate, together with price, max resolution, refresh rate, and another one..)
price unfortunately comes first Sad

i'll probably buy a bestselling one, like a Samsung Syncmaster 793DF (it was/is very popular among the 17 inches CRT monitors in here, everyone has it!)

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
