Yeah I knew the instant I posted that -someone- would try to make a pseudo claim that those aren't representative of "real-world" usage.
There are 3 points to consider ...
1. We can't even display lossless pictures such as .PNG or .TGA natively with the built-in firmware so .JPGs were used and saved with 100% Quality.
2. IIRC the YUV transencoding of the 8x8 macro blocks used in JPEG or MPEG are similar enough that the accuracy IS representative -- it doesn't matter if the content is a still image or moving pictures to stress test the PQ. Any other graphic programmers around here to confirm / deny?
3. The second radial gradient WAS inspired from actual content. I was watching this:
and noticed the horrible Mach Banding. I took a screenshot and converted it to .JPG to see how good (or bad) the Panny could display it.
There are tons of "special effects" being done in the grossly inadequate 8-bit / color channel (24-bit color, technically 32-bit with alpha) color depth instead of a proper 16-bit / color channel (48-bit -- technically 64-bit with alpha). Considering one of my 27" IPS monitors displays that yahoo_comcast_merger.jpg with less Mach Banding _inspite_ of the MPEG / JPEG quantization errors present I believe it IS fair to compare the PQ of a Plasma and Other displays. Think of it this way: The beauty is if we can get these "worse case" images to display properly imagine how good everything else looks !
I love my 60" VT60 as much as the next guy (last night I loved the opening panoramic shots of "The Shining"!) I just want the to understand the _limitations_ of the plasma display, see which ones are _still_ around from when I bought my 42" panny 10 years ago, how to work around the issues, and get the best picture possible. Posting screenshots that everyone can provide their collective wisdom is a good starting point. Sticking our head in the sand ignoring the problem does not make it go away.
THAT was the point, er, points. :-)
Edit.1 Added note about alpha channel
