In my case, I update since I can roll with the changes and know how to yelp at the makers.
But in your case, you have no reason to let it update.
To update or not?
My tv picture is perfect !!!
I still have 1155 original firmware,
and have had multiple opportunities to update different software.
Should I update?
Is there any chance this will adversly affect my perfect picture?
Samsung says no, but I only trust CNET.
If so, what are the benifits to update?
PS. Internet stories claim detrimental effects.
