i have question about the viewing angle in samsung smart led tv model UA40D5500 because when i sitting in side view of TV the contrast of picture is changed than in front of TV? Is that normal
Thanks in advance
A friend's 46D7000 doesn't seem to have this problem at all.
This usually depends on panels used. Cheap panels (TN) have a very small vieweing cone. IPS and PVA panels have a wider angle.
The strange thing is that looking with a microscope at the 46 and 55 panels, they seem to be the same panel type.
I then guess it's a polarization effect due to different polarizers.
"Ultra clear" is probably a brand name.mo3taz wrote:My Panel is Ultra Clear Panel so is that cheap panel?
Panel types are:
TN (quick response <5ms) cheap and small viewing angle, only 262144 possible colors (6 bit)
PVA/S-PVA good color gamut, 8 bit color, medium-expensive
IPS/S-IPS expensive, 8 or 10 bit color depth, normal or wide gamut.
H2-IPS wide gamut, very expensive, best color depth 10 bit.
Thera re also some other panel types around.
The best way is to display a white or grey image and then take a picture of the panel (with a good zoom).mo3taz wrote:ok where i can get info about my tv panel ?

My TV Model: UA40D5500RR
Anyhow I checked 46" and 55" D series panels and they are both PVA HQ panels. I don't know about the 40".
To know that you must get a picture of the pixels like in this picture:
