That's why in the first poit I made in this forum, I said the correct setting for sharpness is OFF... but Off is just about impossible to find without a test pattern (gray background with black lines of different thicknesses)
. You need the gray background to see the white halos "sharpening" creates, and you need many thicknesses of black lines because the Sharpness control may not stop affecting all the thicknesses of black lines at the same time. So you want to find the setting where NONE of the black lines have white halos around them.
The test pattern also needs to have horizontal and vertical lines because some sharpening controls only control one of the two
... some displays and projectors have a SECOND control somewhere else that controls the white halos around the lines in the other direction, but it will be labeled something other than Sharpness.
That's why you use a pattern, and why you have to look for both horizontal and vertical lines.
First. . . I am not disputing what you are saying. We get the OFF thing.
If you take a look at the Disney WOW pattern it has both text and horizontal and vertical lines . . . . against a gray back ground. Exactly what you speak of. . . which is why I like it.
My LG has no OFF position. . . it starts at a center point of 50 as you may know. . . which has already been covered numerous times regarding this topic. However, as you say, each TV is different and difficult to determine where this OFF Point you describe is. Which is why I like the Disney WOW disc sharpness pattern. When I use AVS HD709, DVE, AVIA, etc. and cross checking them I get differing results. . . in other words what looks "right" on one disc pattern shows up as either softening or shows some haloing on another.
The Disney WOW disc having both lines and text of incrementally smaller lines plus fine horizontal and vertical line patterns against a gray background. Exactly what you mention . .. which is why I feel it is ideal and works best from the previous sources I've used.
I'm not disputing what you are saying, yes, the OFF point is what is desired. I just find that difficult to determine for all the reasons you and I have just stated. And the Disney WOW patterns give me the best results so far as Media Assisted Discs go.
Summarizing. . . we get it. .. . . OFF is where it should be. . .. but that can only be determined by the user on the particular display or TV they are viewing.
