-Samsung TV Line-up 2019-

Δεν φτανει που η samsung με τα φιλτρα για καλυτερη γωνια θεασης,χανει σε contrast modulation, τωρα και με την επεξεργασια A.I. οπου εφαρμοζει dynamic pixel quad rendering, της κοστιζει σε επιπλεον contrast, φωτεινοτητα.

Ομως σαν να μην εφταναν αυτα, τωρα μαθαινουμε πως εχουμε και "κλεψιμο" α λα Volkswagen gate.

Οταν η Α.Ι. της Tv αντιληφθει πως παιζει διαφορα test patterns οπως π.χ. 1:1 checkerboard, απενεργοποιει το dynamic pixel rendering, για να ανεβασει τα επιπεδα φωτεινοτητας και contrast, που ειχε χασει με αυτη την μεθοδο επεξεργασιας εικονας.
Στην ουσια οσες μετρησεις παιρνουν οι calibrators, αυτες ειναι λαθος, μιας και δεν υπαρχει μεχρι στιγμης κανενας τροπος να ξεγελαστει η Tv και να μην καταλαβει πως τρεχει test patterns.
Ετσι, με τα patterns απενεργοποιειται το dynamic pixel rendering και σε κανονικο υλικο ξανα ενεργοποιειται.

Although the TV does not officially have an LED blanking system, there is a hidden dimmer system in the background that manipulates the brightness curve. The graph below shows that the gamma parameter is much higher (2.8) in places than it should be (2.4), which in some scenes can lead to poorer visibility and even loss of detail in shadows. The ideal chart should basically coincide with the yellow line.
A stealthy dimmer cannot be turned off, which is a pity.

...As you can see, the Samsung 65RU8002 does very well in dark scenes - I'd say even better than the smaller 55RU8002. What unfortunately connects both models is the "secret dimmer". Well, like the smaller brother, 65RU8002 does not officially have a diode blanking system, which did not prevent the designers from implementing a hidden and out of user control (a fe Samsung!) Dimmer of the entire screen frame (frame / global dimming) manipulating the brightness curve. In order not to repeat, for details to what extent it negatively affects the brightness characteristics, I refer to my earlier review of the 55RU8002 model .

So in the black and contrast category, despite the similarities, the winner is the larger 65RU8002...

351 cd / m ^ 2 on the 10% board (305 cd / m ^ 2 on 55RU8002)
284 cd / m ^ 2 on the board 5% (247 cd / m ^ 2 on 55RU8002)

Warning! Samsung UE55RU8002 is a TV with two different matrices!...http://www.tvtest.pl/samsung-55ru8002-jeden-model-dwie-matryce/

Here is the evidence - comparison of matrices, their parameters and functions:

1.layout of subpixels
2.matrix designation in the service menu
3.label on the back
4.parameters and functions


1. Subpixel system
01-Samsung-55RU8002-panel-v1.jpg

version no. 1

02-Samsung-55RU8002-panel-v2.jpg

version no. 2


2. Matrix designation in the service menu
02-v1.jpg

version 1 (55A1AU0NR)

03-v2.jpg

version no. 2 (55L1AU0NR)


3. Label on the back
05-v1.jpg

version no. 1

06-v2.jpg

version No. 2


4. Parameters and functions

................................version no. 1 version No. 2
matrix manufacturer......Samsung...........AUO
contrast ANSI.................3815:1...........5061:1
UHDA-P3 cover (wide range of colors) according to CIE1931xy...85%.....91%
non-switchable dimming of the whole frame..so....no


-----------------------------

And one more thing. Just don't think that the 55RU8002 case I have described is isolated. Examples are:

Samsung 55Q60R - at least 2 matrix versions
Samsung 50RU7022 - at least 4 (in words: four) matrix versions (!!!)

The biggest (positive) surprise for me was, however, that Samsung engineers gave up the non- switchable (at least from the publicly available menu) global dimming of the entire picture frame ( frame dimming / global dimming ), which from the purist's point of view is obviously unacceptable. In the newer version of the 55RU8002 model (with software number 1335), fortunately, we do not have this poop anymore.

Όσα πάνελ Samsung έχω μετρήσει κι εγώ εκεί γύρω τα βρίσκω. Κι ο Vincent το ίδιο. Και άλλοι...

Μόνο στο rtings τα μετράνε πάντα στα 6000-8000:1 (που δεν υπάρχει single layer πάνελ LCD με τέτοιο native contrast)... :flute:
