Well I finally checked and it did have the convergence off slightly so I used the panel alignment and it honestly looks sharper. It may just be my imagination but I feel like the image looks better overall.
My question was about how many increments consisted of a whole pixel? I remember some back and forth about that so if anyone remembers the discussion and could help I'd appreciate it.
10 Increments make a whole pixel and I'm pretty sure that is mentioned in the Owners Manual. This is vital to know because then +7 has the same effect as -3 etc.
There's some debate as to the benefits of using panel alignment. Yes it will eliminate color fringing in most normal imaging and it can have a dramatic effect on how the internal menus look. However, it does reduce resolution in the affected color. This effect is more subtle but it can clearly be seen as introducing spurious color into1080P resolution patterns that consist of alternating black and white lines of a single pixel in width.
Personally, I recommend the following:
1. Adjust the panel alignment from up close to the screen to get as good a convergence as possible just using the whole panel adjustments (no zones)
2. Change +/- adjustments so that no adjustment has an absolute value greater than 5 (i.e if you have +8, change it to -2 and vice versa)
3. Watch for a few days/weeks with regular program material (not test patters)
4. Return to your adjustments and take two intervals of correction away to bring it closer to zero alignment adjustment (e.g if you have +5, change it to +3; if you have -4 change it to -2).
5. Don't stress about how it looks right up to the screen but instead watch a few more days/weeks with regular programing.
6. If the fringing really bothers you, return to the adjustment values from step 2, but otherwise leave things as they are.
My testings with 1080P test patterns, show that the "color shifts" that the panel alignment introduces is negligible at adjustments below 2 in value and almost completely imperceptible at a value of 1. As such, one should really use values greater than +2 or less than -2, ONLY if the color fringing is still really driving you mad with regular material when you constrain your adjustments within these limits (-2 to +2).
Otherwise, I think you can get the best of both worlds by limiting your adjustment between -2 and +2.
