Calibrating Sony Xbrite screen

Anyone with any tips for calibrating the Xbrite screen. Yellows are way too orange. Tried playing with the gamma profiles...no go. Downloaded "QuickGamma" and was able to get it closer but had to max out the Gamma settings all the way to 3.1 where ran out of adjustment and still a titch off. Any tips? Beautiful display but if I can't bring colors inline I will return it.

wow, that surprises me.. what drivers are you running, the calibration on my 260 seems spot on.. although i haven't run the gamut of testing.

Try looking at something that should be very yellow.

For example, go to generalmills.com and look at the Cheerios box. The page itself should be a fairly pure yellow.

http://www.cheerios.com/



check out the Honeynut version. The bee's face and lettering should be bright yellow with no orange tinge (I've got the actual box in front of me.)



another familiar image



Notice how orange it is. I noticed it first when viewing pictures of flowers I knew were nearly pure yellow...they had a distinct orange tinge to them. The default settings have great contrast without washing out any detail on either end of the spectrum but they are off. Perhaps I need more powerful tools than the freeware and shareware ones I tried but I'm concerned that I might just have hit the end of the adjustment range. On the other hand the Samsung display on my Dell 9300 calibrates nicely. Too bad it doesn't have the contrast and dynamic range of the Sony display. In the end I may just stick with the less striking Samsung display because color accuracy is more important than dpi.

Did a little more analysis and noticed a strange thing with the Sony.

As most people know, CRTs are much better for editing pics than LCDs. LCDs can give different colors from just moving your head around on the screen. Adjusting a gamma bar is only possible using the center of the bar...the upper and lower portions will be at a different angle and therefore cause a different correction factor. Bottom line, angle is critical when using LCDs. Whatever angle the LCD is to you when you adjust it must be the same angle you use for editing.

With the Sony display, moving your head down just a titch...or to the left or right, causes the yellow image to quickly turn orange. On the Dell display I have to move my head much lower for the same effect and there is barely any color transformation moving left and right. The Sony seems to drive the colors off as much to the left and right as it does up and down.

My sony was just way too bright and washed out. I needed it to match my desktop's screen which is properly set using a calibration device(Spyder). The Spyder for some reason doesn't work on the sony, so ended up just placing the two sceens side by side and eye balled it.

The screen on my A190 seems pretty accurate. There is a slight orange tinge to the packs in your photos, but that is because I have gamma and brightness down on my screen to improve black levels. I can easily adjust that out though. As for viewing angle, I have to really move my head or the display to do change the color in the way you describe.

Which video card do you have?

I have the ATI 9700, which allows me to adjust the gamma, brightness and contrast for Red Green and Blue individually or together. I can also load various color profiles from the Color Managment section of the Display Settings. I use the Adobe defaults, since I use Photoshop, but there are many others to choose from.

The A190 display isn't as accurate as a CRT or a really good graphics display, but I've not seen better in a notebook.

Cheers

Samsung LCD has much more accurate colors

I've got the same ATI graphics card and tried adjusting the settings with no joy. I may try it again now that I have a better idea what is necessary. The Samsung display on my Dell 9300 was much more accurate but not nearly as bright and sharp. If I could figure out how to calibrate the Sony I would keep it but it is essential that I can get somewhat close color accuracy from it.
