I have read on here that the DVE blue filter glasses are not accurate. Should I buy the thx glasses, digital video essentials, or use both?

Greetings

All the blue filters are not accurate. They were designed for CRT phosphors.

The purpose of the filter is to get you into the ballpark of where correct should be. YOu use your eyes as the final determiner after that.

+1 with Michael, your eye is the final judge.
another option : some display have a "blue mode only" more "accurate" than blue filter

So, do I need to spend the money on blue filter glasses. Or should I do it by eyeball?

if you have a meter, just use that

color isolation modes in the TV are the next best option

color filters are the least reliable option

none of the options are 100% foolproof, though, so you need to verify skintones and other natural colors/objects with reference material

The Spears and Munsil disc came with a one eye filter that had three options - 1x, 2x, and 3x for their blue filter. I've never heard doubling or tripling the blue filters mentioned on these forums. What effect does that have as to accuracy?

Different displays need different levels of filtering to do a proper calibration, so the filter allows for 1, 2, or 3X filtering.

How useful are the green and red primary filters? Will they let you take it a step further?
