Sure, perfect is not obtainable. I have seen some really bad examples where it is likely to show in actual content. It's hard to know what that threshold is but I have seen LCD's where I can clearly see it in actual content. I guess I'll just have to use may best judgement and as long as it does look like the really bad examples that will be good enough.No panel is perfect. I never bothered to run slides on my C8. The pq was gorgeous from any source on my C8. I'm sure the panel is not perfect but if I don't see problems with any content, then I'm not going to go looking for issues. The degree of "acceptability" is up to you. Obviously the really bad examples are not acceptable but anything less is your call.
Anything else I should look for that have been known issues?
