Die ersten Messwerte der neuen Samsung Plasmas sind da....
Vom C7000 gibts mal einen ersten Bericht. Relativ enttäuschend - SW
auf aktuellem LG Niveau, 2D to 3D nicht besonders. Farben beim LG
neutraler....
Also - der einzige 3D Plasma im Mittelsegment - aber bildtechnisch
nicht besser wie die Vorgänger B8507B680. Also das ist mal ne echte
Enttäuschung muss ich sagen. Mal gucken, was beim 8000er kommen
wird.
Nicht vergessen - kalibriert sind die ganzen LG Modelle gleichgut -
alle haben die selben Panels - nur die 750iger und 950iger haben
andere Filterscheiben. Diese wirken sich v.a. aber nur bei heller
Umgebung aus.

Earlier this week, I met with Chris from
Cleveland Plasma to take an in depth look at the new Samsung
PN50C7000 3D capable plasma and compare it’s performance to a
couple of other sets I had calibrated. The C7000 is a perfect
example of the new breed of sleek and slim plasmas, and it’s
profile looks fantastic from any angle. It seems to pick up an
average amount of glare compared to other plasmas, with the
reflections perhaps a bit more diffuse than on the LG
plasmas.
Though I did not have an opportunity to see the C7000’s 3D
processing, I wanted to see just how good it’s core performance
was. Unlike Samsung’s UN46C7000 LED LCD that I reviewed recently,
the picture mode is selectable even while in 3D mode, so you can
enjoy a more accurate picture in 3D.
I took measurements of different picture modes before making any
changes. Standard mode (not shown) was not very watchable in my
opinion, with a very blue/purplish cast to the white balance, poor
gamma that will give brightly lit faces a clayface or caked on
makeup look, and a low light output of only 19.4 fL. Samsung added
a new mode called Relax, and it’s performance is shown in
attachment 1. Relax’s measurements suggest a more watchable picture
than standard mode, though the white balance is still somewhat
purplish and the colors are pushed. Movie mode (attachment 2) shows
pretty good performance overall, though the color gamut is a bit
narrow and the green color luminance is pushed. Overall, movie mode
appeared to be a great starting point for calibration.
The C7000’s secret service menu was sparse, with little of interest
to calibrators that I could find. Thankfully, in movie mode a
fantastic selection of advanced calibration adjustments is
available. Samsung added a properly functioning 10 point white
balance/gamma adjustment, which can be used with the proper test
equipment to fine tune the performance. The C7000 also includes a
complete, properly functioning CMS (Color Management System)
adjustment, gamma presets, and a 2 point white balance control that
can be used in conjunction with the 10 point adjustment. The shadow
detail adjustment I saw on the UN46C7000 was missing. Fortunately,
it’s shadow detail was good enough already that I felt no need for
the missing adjustment. There is also a skin tone adjustment that
makes on the fly adjustments to make skin tones more or less
red.
The C7000, like many other Samsung sets, has a switchable black
level when fed an HDMI RGB colorspace signal. However, it has color
decoding discrepancies with RGB colorspace that are not there with
the more common YCbCr. That means some video games and DVI sources
may not have as accurate color as Blu Rays and other HDMI video
sources.
1080i and 1080P resolution in dot by dot mode was perfect and
strong. Black level, measured with a low light sensitive
colorimeter profiled off the Eye One Pro meter on this TV at the
time of calibration, measured .033 fL. Later, after a full cool
down period, the black level measured around .026 fL (see link
below). Black had a very slightly greenish cast. The modified ANSI
contrast ratio measured 958:1. The C7000 could be calibrated to be
nice and bright; I calibrated peak white to match 2 other plasmas
nearby to facilitate a three way comparison at around 45-47 fL,
though it could have easily gone higher.
The after calibration measurements are shown in attachment 3. The
10 point adjustment worked great to make the white balance and
gamma nearly perfect. Likewise, with the help of the CMS
adjustment, colors matched the HDTV standards to a degree that is
rarely, if ever, seen in other sets.
Te first thing that jumped out at me as I put some familiar
1080P/24 Blu Ray material on was the vibrant color. Initially, it
overshadowed everything else; those carrots in the DVE restaurant
scene jumped right out at me, and a few seconds later when the
flesh tones came into the scene they looked extremely rich but a
little too ruddy.
Shadow detail looked good; compared to some other sets the shadow
detail may appear a bit hard to see, but in my opinion it was
balanced perfectly. Shadow detail was noticeably better than on
Samsung’s previous models before they implemented the 10 point
adjustment. Resolution, detail, smoothness, and stability were all
great; there was no annoying graininess or pumping in the picture.
However, black level was noticeably not inky black. From the
material I looked at, it appeared that 1080P/24 was displayed at 60
Hz rather than a multiple of 24, though on most scenes it was hard
to tell. While the image was without question very impressive, I
decided I should recheck my CMS calibration to see if I could find
an explanation for the explosive colors.
Using the set’s color isolation controls, I discovered that the
C7000’s color decoding changed a bit with picture level. I redid
the CMS, starting with a lower overall color setting, and found
that eliminated the issue. I rechecked the demo material, and
things looked very similar; though I felt the flesh tones were a
little better controlled this time around. I felt that the flesh
tones at this point, though still overly ruddy, were reasonable
enough that I did not want to sacrifice accuracy or overall color
to try to make them more to my liking. The skin tone adjustment,
which I left at the neutral position, can be used to lessen the
sunburnt look while minimizing the compromise to other
colors.
I feel that Samsung may be doing a bit of behind the scenes color
processing that will make the C7000 stand out relative to the
competition. While I feel it is a bit overdone, I could understand
many people preferring it’s vibrant colors over a more accurate but
comparatively bland picture. In fact, I think it’s just the look
that will draw people to it. Fortunately, there’s enough color
adjustments that if you feel it is a bit overdone, as I did, it is
possible to bring them more in line with your taste.
Since I had two other recently released plasmas nearby that I had
just calibrated, I couldn’t resist doing a comparison between the
C7000, the LG PK750, and the Panasonic G25. While screen size
varied, I did calibrate all of them to a similar light output. This
particular LG PK750 was not the sample I originally reviewed; it
was the one on which I was able to successfully adjust it’s 20
point white balance/gamma adjustment. That will not be possible
most of the time unless LG makes a correction in it’s adjustments,
and it gave this particular PK750 an advantage. Please see my
review of the PK750 for the complete explanation.
With a 0% black signal, the G25 had the darkest, inkiest blacks in
a dark room. The PK750’s blacks were neutral toned but quite a bit
lighter than the G25. It is possible, however, that as the G25 ages
it’s black level would be more similar to the LG and Samsung
because of it’s allegedly rising black level. The C7000’s blacks
looked very close to the PK750’s, though a bit more greenish. With
the lights on, the G25 suppressed reflections better than the PK750
or the C7000. Looking at the demo material on the DVE Essentials
Blu Ray, I saw excellent skin tones on both the G25 and PK750,
while complexions looked a bit too red on the C7000. There was a
textured look on the PK750 that was only barely noticeable and was
probably a byproduct of some edge enhancement. All three sets
seemed to handle pans and motion about the same; there was a slight
jerkiness that seemed to suggest none of the sets were displaying
the 1080P/24 signal at a multiple of 24. The G25 and PK750 had good
depth and pop, while the C7000 had richer, more vibrant color. The
G25 had neutral toned but slightly overemphasized shadow detail.
The PK750’s shadow detail was a bit less neutral with a slightly
greenish tone, but also appeared a bit overemphasized. The C7000’s
shadow detail was probably the most neutral when both color tone
and visibility were taken into account. The G25’s image seemed just
a tiny bit crisper.
Overall, I think the C7000 is a very good set with textbook
measurements. It's color may be too vibrant for some while the
cat's meow for others; and it's black level is not as dark as I
would prefer, but in every other way it is a stand out set.
Edit: So, hab mich mal ein bisschen weiter eingelesen. Die 6000er
Serie zb soll ebenfalls nicht gut sein - ca gleichauf mit der
B680/850 Serie. SW teilweise schlechter.... Also wenn die 8000er
Serie das nicht rausreißt, bin ich doch etwas
enttäuscht/überrascht. Wer hätte das gedacht, dass LG Samsung
überholt.^^
Aber immerhin haben sie das Surrproblem unter Kontrolle
gebracht.
Btw - der C7790 ist ein Mix aus der 7er und der 8er Reihe, letztere
soll in Europa nicht erscheinen... kann doch nicht sein, dass das
alles war, was Samsung zu bieten hat?
Die 6er Serie braucht man sich garnicht kaufen - um nichts besser
als die 680/850iger Modelle (außer dass der 50hz Bug weg sein
soll), die 7000er Modelle nur Mittelmaß, aber mit 3D Funktion. Und
die 8er Serie erscheint bei uns nicht....
Lang lebe LG - einziger Herausforderer von Pana :rofl:
