So, I got a new TV today, a Sony KDL60EX645 and did a calibration using an i1Display Pro.

The Sony lacks a CMS, so I figured I'd go about and adjust the color and tint after I finished the brightness, picture and grayscale.

I remember I read before that to adjust color and tint on a TV using a meter, you pull up a 75% Red Saturation window for the color and adjust the Y value until it's 21% of a 100% White Y value.

To adjust Tint/Hue, you bring up a 75% Cyan Saturation and adjust the x and y until they are close to the proper Cyan value.

However, when I did it this way, my numbers for Color & Tint/Hue were 43 and R7 respectively.

I figured I'd humor myself and cross check the values using a Blue Filter and the Flashing Decoder Bars window... When I looked, the Color portion of the bars were flashing a bit, Tint not so much, but a little as well.

Adjusting using the filters and my eyes came to values of 52 and 0 for Color & Tint/Hue.

Which should I go with in this situation? Should I just keep the meter value? The picture didn't look bad with the 43/R7 from the meter reading... but the 52/0 one looks OK too, though a little punchier. I'm not sure if the 52/0 is an accurate picture, though, as I am trying to trust the meter more...

Please let me know your thoughts and thank you.

Current HT setup:

Samsung UN65F6300 65" LCD HDTV, Polk CS20 Center, 2x Polk Monitor 75T Fronts, 2x Polk TSI300 Backs, Polk PSW110 Subwoofer.

No. Adjust Red to 21% of the same relative luminance White. eg. 75% Red = 21% of 75% White, 100% Red = 21% of 100% White, etc..


Edit: Quote Huffman:

Relative luminance is the luminance of a color expressed as a percentage of the luminance
of white at the same level of stimulus. The relative luminance of reference white is always
represented as 1.0 and colors are shown as some percentage of that. For example, the
high-definition standard for the luminance of red is 0.2126. That means that red should
measure 21.26% as bright as white at the same level of stimulus. Relative luminance is
useful for gamut specifications and calculating the dE of color. For more information about
dE, refer to dE Method, p. 30.

So I should have done a 100% Red (Color and not Saturation) Window and adjusted to the 21% of the 100% White Window... I'll give it a whirl!

I see the problem with my display now.

Both results are accurate... in a way...

Checking the meter... when I adjust color to 43, the luminance of Red is correct... but then luminance of Blue and Green suffer.

Putting color at 52, luminance of Blue and Green are GREAT... but then luminance of Red is too strong.

In this situation, what would you do?

Also, re: the Tint/Hue control... Moving all the way to R7 gets Cyan as close as it's going to get... but then Magenta and Yellow aren't that great.

Magenta looks the closest at R1.

Yellow? Well, have to go to G2 and even then it's still not correct.

I'm probably not going to get a perfect setting for this, but was just wondering suggestions from you all.

I decided to adjust for getting red and yellow to be the most accurate.

If someone knows how to adjust the red luminance in the service menu, I'd be grateful if you could share. Then I could get the red luminance value to be accurate to the blue and green one when on the same color level. Right now, blue and green match when the levels adjust, but red is overpowering.

I used a service menu code I know, the Display, 5, Volume +, Power but I didn't see anything there. I know there was another service code for Sonys before, but I've lost it.

Thanks in advance again!

Found my old text file with another alternate service menu code: Left - Right - Mute - OK - Mute - Menu.

GOLDEN NOW, adjusting that Red Luminance now.

EDIT: Actually, I thought I was golden, but I can't get it to save my values.

EDIT2: NEVERMIND, figured that out too.

Don't leave us hanging, how do you save the settings? Is it MUTE - ENTER ?

I have a KDL55EX500 and have been trying to get into the service menu. I can get grey scale good, but I have been looking for the CMS controls.

It's still not a true CMS. You can go into the second service menu using the Left, Right, Mute, Enter, Mute, Menu combination, then go to "Color Temp" and make adjustments to R, G, B gains and offset. The precision is much more fine than the "White Balance" user version... but it's still no CMS.

If you improve your picture using that menu, BEFORE you press MENU or EXIT, go to the "Data Backup" option and select "W/B" then hit ENTER.

You can then exit the menu.
