Yellowish tint

BossDogg · 07-12-2009, 04:52 PM

Hey everyone

I have calibrated my Sony XBR9 and I have a good picture.
The thing now is when I am watching a program some of the
people seem to have a yellowish tint to their face.
I used the Avia disk, everything else seems fine.
How can I get rid of this yellowish tint.

thanks,

Boss.

What user controls were adjusted?

Nice thing 'bout the high end sony's is the reset feature as well.

Cinema mode, warm 2 ct setting and a dark room gets you so close to d65 that further calibrations really necessitate a colorimeter to reduce Delta e error, and that improvement is marginal.

d6500k,

What settings would you recomend for my set on the color/picture/brightness and on the advance area there is R,G,B (red,green,blue?) and what is Hue?
this is a xbr9 television. your reply will be appreciated......Boss

First, hit the reset function to place the display back into its factory mode.

Then, if you do a lot of viewing in a darker room watching films, select the Cinema preset- Warm 2 color temperature.

Relax and watch a movie...

If, on the other hand there is a bunch of ambient light and your viewing mostly TV shows, select the Standard preset. Once again just enjoy it for a bit.

After a few days or hours, depending on your level of satisfaction with the built in presets...

Place the Avia disk in the bd-dvdplayer and set up the black and white levels first in your "custom" preset. Take your time and remember to be aware that the lights in the room will affect the outcome. (IIRC, the '9s have two custom settings available. You could use both for lighter and darker rooms). Dial in the black level with the "moving black bars and half gray" pattern. Nail it to where you can just barely see the left hand bar, then turn down the brightness control just one click.
Now adjust the white level with the "picture or contrast control" and the "10 step crossed gray scale" pattern. Be sure that you can see a finite difference between the brightest two rectangles. While there, you can also verify that the two darkest boxes are also differentiated. The Black and White level controls do interact to a degree, so some time spent here is most valuable.

OK, now for color and tint (saturation and phase).

With the SMPTE color bars up (blue) use the bit of blue plastic and adjust the "color" until you can barely see the blinking light boxes in the top of the pattern. Do the same for the tint. Again there may be a bit of interaction so get them as close as possible. Put in a film at this point and watch it for a bit pausing the picture when there are humans in a daylight scene. If they look like they are really sunburned, simply turn down the color control until skin tone appears natural.

Your done...

The RGB cuts and drives and the color management controls you found are for the correction of the gray scale and location to accurately measure each primary and secondary color. You need a specialized tool (read expensive for a good one) and some knowhow as to its implementation. Sony does an OUTSTANDING job with regards to the plotting of the Pri/sec's so touching anything there is a waste. The RGB controls can be used if you wish with that same 10 step crossed gray scale pattern on Avia, but.... using the "warm 2" preset gets you awfully close to spot on as well.

Dial in the B/W levels! Adjust the color and tint to suit.

A more complete "basic setup guide" is on my website.

Hire a pro if complete accuracy is demanded.

Have fun!

And how to make the bright colors better? My XBR9 is great, but I can not set the bright colors (white, bright yellow, bright blue (sky), etc.) better. Sometimes, I see them have light blue in my yellow and white.

Thanks alot!

Edit: I am watching BOLTS, so I can sse that bright color changed!

d6500k · 08-22-2009, 08:14 PM

You might try the same protocols as mentioned above, especially the cinema preset and warm 2 setting in the user menus.

If you indeed still have "light blue" tinting to the highlights of other colors... when the display is approaching max. white light output, then you could reduce the blue gain a notch and verify if that helps to reduce the anomaly. Run the test with the DVD/BD in still frame to check. You should be able to see any reduction in "blue tint" immediately.

I have a question on the Avia 2 calibration disc: in the setting for brightness/contrast, you have the stack of boxee and the 2 moving bars.
The left bar you adjust it until it is barely visible, the right side bar what do you do/adjust with it?

thanks

Boss

d6500k · 08-26-2009, 10:59 PM

Actually, adjust the black level (brightness) until the left hand bar just disappears. Give that a shot with a film. If you find that the picture seems to be just a tad too dark in the darkest areas, revert to the previous setting.

Each of my displays, from a small lcd to a 92" screen require that I adjust black levels occasionally with certain films. Pretty soon, you will make the adjustment without the use of a test pattern, and that is AOK.
