I used the blue filter on probably 20 or 30 different displays and not one time did any of them produce the proper settings for color and tint (more than one disc and filter were tried). the discs WAY over-state how accurate the blue filter method is. If that's the case, why not just use your eyes and forget the blue filter. In fact, every good setup disc will tell you that after you use the blue filter to set color and tint, if the picture doesn't look right to you, adjust color or tint until the picture DOES look right. Few of the setup discs even mention backlighting (aka bias light) as a means of improving apparent black level and reducing eyestrain at the same time.Įverything else on the disc, and even the 'blue filter' method for setting the color and tint controls fail so often that they are really no better than using your eyes to set those controls. They always tell you something very misleading and make you THINK that the highest Contrast setting you can use without clipping is the best Contrast setting. No setup disc I've ever seen tells you that. So lower it in steps till you no longer detect eyestrain. If you are in a dark room and your eyes feel strained after a couple of hours, chances are your Contrast setting is too high.

So all you can go by lacking a meter is to watch something for a couple of hours, like a movie. No setup disc on earth is going to tell you how to figure out (without a meter) which Contrast setting gets you 35 fL. You want roughly 35 foot-Lamberts for 100% white in a dark room. But that highest setting is not the RIGHT setting. All you can do with a setup disc is tell whether your display clips white or not and if it does clip white, you can learn the highest setting you can use where there is no clipping. Some may argue that you can set Contrast with a setup disc.

The only controls you can set with accuracy using a disc are Brightness and Sharpness.
