Its great that your happy with the BV7 and that one considers it such a leap in LCD panel and technology that it renders all known LCD issues defunct. This will be of great comfort to the manufacturers of LCD

Lets leave it at that- its all down to personal preference at the end of the day and human nature dictates that once a purchase has been made one will do anything to defend that purchasing decision- we all do it!

I found a web page, which of course I can not find again now, that indicated the Beovision 9 had a standars contrast of 3000:1 with a maximum contrast of 10,000:1?

It depends hows its been meansured have a look here----

Contrast ratio is the difference between the brightest and darkest parts of an image, measured in discrete steps, at any given moment. Generally, the higher the contrast ratio, the more realistic the image is. Contrast ratios for plasma displays are often advertised as high as 20,000:1. On the surface, this is a significant advantage of plasma over other display technologies. Although there are no industry-wide guidelines for reporting contrast ratio, most manufacturers follow either the ANSI standard or perform a full-on-full-off test. The ANSI standard uses a checkered test pattern whereby the darkest blacks and the lightest whites are simultaneously measured, yielding the most accurate "real-world" ratings. In contrast, a full-on-full-off test measures the ratio using a pure black screen and a pure white screen, which gives higher values but does not represent a typical viewing scenario. Manufacturers can further artificially improve the reported contrast ratio by increasing the contrast and brightness settings to achieve the highest test values. However, a contrast ratio generated by this method is misleading, as content would be essentially unwatchable at such settings.

Plasma is often cited as having better black levels (and contrast ratios), although both plasma and LCD have their own technological challenges. Each cell on a plasma display has to be precharged before it is due to be illuminated (otherwise the cell would not respond quickly enough) and this precharging means the cells can achieve a true black. Some manufacturers have worked hard to reduce the precharge and the associated background glow, to the point where black levels on modern plasmas are starting to rival CRT. With LCD technology, black pixels are generated by a light polarization method and are unable to completely block the underlying backlight.

Hi all,

From this article:
http://forbruker.no/digital/tester/tv/article2002501.ece

The picture shows a comparison between a new pioneer and a panasonic plasma display(TH-42PX70).

I would have liked to se how the BV740 compares to these two.

 

I have always been given to understand that Manufacturers' quoted Contrast Ratios have been found to be grossly optimistic when the relevent TV has been tested in the lab.

Does B & O quote realistic data?

The BV7 Mk111 would have to be a significant improvement over the Mk11,which I found to be disappointing in it's PQ,to sway me away from a BV9.

I've seen them side by side, and the bottom line is that the BeoSystem 3 is great!

The 40" screen has an advantage when it comes to resolution - or it seems to have more detail - compared to the 50". Black is black on both models IMHO, but the BV9 gives me a "BeoLab 5"-feeling: not adding anything, very pure and true to the source. Look at skin tones, the BV9 has the edge. But given the price gap, the BV7 is the obvious winner unless money doesn't matter.

As someone of you know I worke as photographer and use highend camera Hasselblad with 39mpx

So for me right true color is very importent. Same way I look at LCD versus Plasma and if you want true color(realistic)

plasma is far better than LCD. Skintones etc. On the other hand LCD is more sharp and crispy, but little exxagerated color (right word?) 

So this is more a subjective feeling if you like LCD or Plasma. BUT plasma deliver the same picture as our eyes ses it, LCD not!
