Hello,

I have been using warm setting since i know this should give me the more accurate temperature setting for 6500k. But i`m finding sometimes that the warm setting make the picture "flat" hard to explain. Is this how it should be?
Make sense what i`m saying?

The cooler the picture the more "pop" i`m seeing. while Normal is too blue to my taste and also feels artificial, the warm setting whiles looks more natural and i like it more, sometimes i feel it flat the picture.
I know i can`t do anyting since i don`t own a colorimeter but i was wondering if the flat "picture" feeling is normal with warmer settings.

Any comments?

Greetings

Is this like saying that 2+2=4 and four is kind of a small number. Maybe you like bigger numbers. You can have them, but the answer would be wrong.

On an LCD set, a calibrated image can have the backlight maxed out just like the vivid mode or any other mode. Whites simply are not blue tinted. But since our eyes see the blue whites better, we figure they have to be brighter as a result.

And of course the other modes like dynamic don't just give you a blue tint, they may also crank contrast way higher than it should be, You end up losing a lot of detail in the image, but if you didn't know that you were missing detail, you would not be missing it.

I understand your point. But maybe I explain myself wrong. Does a warmer setting gives you a flatter picture? Is this correct what I'm experiencing?.

I like warmer because it looks natural and also see a flatter picture compared to normal temperature.

This should be like that? Or there is something wrong with the warm setting on my display?

warmer shouldn't mean flatter, but there are many things a TV could be changing when you change picture modes or color temperatures.

It could be that the gamma shifts significantly, or perhaps a dynamic contrast setting changes.

Without some hardware to diagnose exactly what changes it's impossible to know exactly.

I think it's normal that warm2 looks more flat looking than cooler settings
Cablebox setting ycc444 givs more pop vs rgb which looks flat.
You could try lowering the red bias about 3-5 notches- if when you turn down color control to black and white you see too much red in the dark parts where it's suppose to be black(this is done later in evening in a black room).
Your gamma could be too bright. Try lowering it 1 notch.You have to turn brightnes up about 5 notches too

That shouldn't be true, ycc and RGB are just different ways of encoding a color. Something in your signal chain must be doing something it shouldn't or RGB is full range and ycc is video.

But this just reinforces my earlier point, that changes that shouldn't have any effect often times do. In order to figure out the why you'll need better diagnostic equipment.

I think plazmapz said he could calibrate and make rgb and ycc look the same? Ive no meter. I have mine set so it's flat looking(lower contrast), but it looks smooth/balanced.a bit on the dim side but not bad.

YCbCr (4:4:4 or 4:2:2) is always 16-235 (video levels)

RGB can be 16-235 (video levels) or 0-255 (PC levels)

If you want YCbCr and RGB to match, use RGB 16-235 (video levels)... that way both HDMI color spaces use the same levels.

Also, you can do the following on the Samsungs (and possibly other brands too that offer a similar control to 'HDMI Black Level'):

Set the source device to output PC levels and set the Samsung TV to HDMI Black Level 'Normal'... this will effectively give you the same picture as setting the source device to output video levels and setting the TV to HDMI Black Level 'Low' or setting the source device to output YCbCr (which is always video levels) and in that case, the HDMI Black Level is automatically correct and grayed out.

The idea behind all this is to be able to use the same picture settings on the TV for all three HDMI color space/level options. The only parameter needing to be changed would be 'HDMI Black Level'.
