Some great news for everyone wondering about this so called "SLC1" Panel update. A friend of mine has about four of these monitors, he decided to take a peak inside to find out which build date and rev have which Panel.

Would you look at that, the speculation is correct, there is a newer panel out "SLC1" and seems to come in May 2013 Rev A00 . I happened to receive one of these also and i can tell you the crosshatching is a night and day difference. It really isn't even noticeable anymore with the newer panel. i Have not noticed any inverse ghosting or ghosting issues at ALL. Have done many tests and things seem to be A okay. Also no color tint issues.
Newest Panels are in MAY/JUNE BUILD DATE and onward with a REV A00. Refurbished monitors with an A02 tag also have the newer panel in them.
