Samsung 51D530 Plasma, can anything be done to rectify this without a meter and software ?

By oversaturated do you mean too bright?

Usually when people say oversaturated, I think of a primary that is too far out on the CIE color diagram. But it is also sometimes used to refer to how bright the color is.

If red is showing pink, it seems to me that it would be undersaturated on the CIE color chart.

It's hard to comment without more info...

You might try raising the gamma, if you can, to see if that makes any difference...

Thanks for the quick response, I apologize if my terminology is not correct, yes red appears to bright and has a pinkish hue. By raising Gamma do you mean gamma controls on the set itself ? Samsung has a control that goes from -3 to +3 would that mean an adjustment towards the negative or positive ?

It could be slight undersaturation, but assuming your grayscale is fairly accurate, it is more likely your hue setting for red that is causing you to shift toward magenta and blue, resulting in a pink cast. Can you detect any particular color cast in grayscale? As gremmy indicated, I'd venture your red luminance is too high. Adjusting gamma will impact all of your colors, not just red, but may be your only option if you don't have a 3D CMS.

Yeah no CMS on this set. I'm going to give the gamma adjustment a try see what effect that has. Thanks for the feedback.
