Default dynamic vs normal contrast ratio

My family is considering getting a new TV, and are comparing these two:

Samsung PN58A550 58" 1080P Plasma HDTV

Pansonic TH-58PZ800U 58" 1080p Plasma HDTV

The Samsung says it has a dynamic contrast ratio of 1,000,000:1. What does dynamic contrast mean?

BTW, the Panasonic with it's THX mode is the clear winner when compared to that model Samsung.

Im not sure of the native CR on the 800u but my 80u is 1,000,000:1 dynamic with a 20,000:1 native CR. I think the dynamic is the best it can do and the native is what you see just while your watching it. Im probably wrong and would like to be corrected if I am. I have noticed that LCD's with a 50,000:1 dynamic CR usually have a 5000:1 native CR but they don't tell you that. At any rate the 800u is better than the samsung IMO.

Dynamic Contrast Ratio means absolutely nothing. The methods used are questionable and varies from model to model and brand to brand. All modern displays have a contrast ratio of between 350:1 to 600:1.

I was thinking of buying the Samsung 'PN58A550' tomorrow on sale for $1800(Open Box) or $2000 brand new.

Now I'll have to do some more research.
I don't think I can find the Panasonic for that price in my area.

Dos the THX mode make a big difference?

Sorry for the thread Highjack too..

Are you a diehard videophile? Are you so anal that the little things matter? If not, like I suspect, then go with the Panasonic. The THX stamp on that TV just means that George Lucas and his crew have a pproved this tv for meeting their standards for what a movie should look like. Since Star Wars is one of my faves, that would be a selling point for me. BUT, that stamp also means that the tv was in a certain environment to meet that standard. I doubt your living room will have the exact same lighting and whatnot as Lucas did when they threw that stamp on the tv. Overall, from what Ive read, Panasonics have a better track record than the Samsungs. But in the end, theyre like a Mustang and a Camaro. It just depends on which appeals to your eye that matters. The cheapest Ive seen that model of Panasonic going for is around the $2300-$2600 range.

You are spot on about George Lucas and THX Cert. Was watching The Empire Strikes Back over the weekend. Standard Def DVD, not blueray, using my Philips upconverting DVD player on my Vizio VO32 and this movie was as close as you can get to HD. The detail, the color and of course the sound was just beyond unbelievable. Absolutley amazing.

The THX mode on the pz800 series plasmas is just preset factory settings that are very good, and that is the important part IMO compared to just being THX certified.
